That makes only 2 of the original 8 founding scientists left. https://www.statnews.com/2020/08/25/elon-musk-neuralink-upda...

Elon Musk has been pretty successful at getting top talent to push the limits of engineering, but with neuroscience, it seems the research isn't there yet. What I'm really interested to see is how long Karpathy will stay at Tesla as other self driving projects drop like flies (ATG, Zoox, and most recently L5)

I dunno, self-driving is an interesting computer-vision / machine-learning problem and it is far more interesting than 90% of the stuff a lot of your FAANG companies are spending R&D dollars on. For anyone working in the field, the end goal is extremely rewarding in terms of the long-term beneficial impact on society it would have and the numerous lives it would save.

I don't think Tesla is going to drop FSD R&D anytime soon. They've also built out amazing software infrastructure under Karpathy's leadership to make use of their fleet of hundreds of thousands of cars to run shadow experiments with newer models in the background and continuously collect more difficult and interesting training data so they can improve their models and their internal test-sets for tracking metrics. They are also a relatively lean team from what I've heard, so it's not like they are bankrolling hundreds of very expensive ML PhDs at the moment. It is debatable if they (or anyone else) will "solve" FSD with current approaches, but I think the technology is already pretty fascinating and useful.

> it is far more interesting than 90% of the stuff a lot of your FAANG companies are spending R&D dollars on

Yup. “The best minds of my generation are thinking about how to make people click ads.”

Are they really the 'best' minds if that is what they choose to do? Not in my opinion.
That's not really fair.

If you want to do fundamental research, the jobs are very scarce and, in many cases, not particularly good in terms of salary, stability, or location. A postdoc in the life sciences makes $50-65k/year, often either in a) a high cost-of-living area (Boston, SF) or b) a land-grant institution in the middle of nowhere, which is tough with a partner. These are usually short contracts too--mine is renewed annually. Faculty and Pharma jobs pay better, obviously, but are also pretty thin on the ground.

I like doing research that makes the world better, but doing so is an incredible luxury, even coming from a decently middle-class background. If my family were even slightly poorer, there's no way this would be possible and if one of them were to get sick or hurt, I can't imagine how I'd be able to stick it out.

It doesn't have to be this way, obviously. We could fund more stable positions--and I think it'd probably work out to more/better science per dollar spent. But right now...we definitely don't.

I'd change "the best minds" to the "some of the most educated and technically prepared minds".

And it's not only to click ads, there is a whole lot of engineers (even more in poorer countries such as Brazil) who end up working in banks and finance, mostly to deal with complex spreadsheets.

It's a complete waste of educational investment.

Spreadsheets and finance has tremendous value!
If by "best" we mean, most educated, most capable of solving engineering problems, "highest IQ" etc. (Which is how we generally define best in this context) Then yes.

There used to be a big incentive for the smart scientific and engineering minded types to go into academia, but now the majority go into either financial services or tech work because that is where the high salaries and actual problem solving are.

I read the "best minds of my generation" comment as a reference to the opening line of Howl by Allen Ginsburg. https://www.poetryfoundation.org/poems/49303/howl

Though I don't know if it was an intentional reference or just a coincidence.

Of course it was an intentional reference! The meat of the meaning is in the reference, not the plain words!
Well, the idea is that they demand the highest salary and those who pay the highest salary are companies interested in improving ad-clicking. It's not "abstractly best" but "empirically best". If you get the most money, you are by some definition the best.
The companies might be interested in add clicking, but they are willing to hire extraordinary people who work on whatever they feel like.
I think their described as ‘best’ minds because they graduated top of their class at Ivy League, leading California school, etc.
It is the society failing them by not setting the right priorities.
But, indirectly it becomes an interesting problem (nlp research). If we didn't have people playing / making video games then we wouldn't have figured out GPU acceleration to use with deep networks (backpropagation is fast when you can do matrix multiplication fast).
I’ve heard it also as “making global scale dopamine delivery systems” when bringing in social media KPIs and other addiction-driven engagement like modern gaming monetization models
> Yup. “The best minds of my generation are thinking about how to make people click ads.”

That's better than when the best minds are thinking about how to kill people.

Anyways, it is a good thing that even if the end goal is far from noble, most of the times, invest enough in R&D and positive things come out of it.

On the other hand, “The average minds of my generation are thinking about Instagram.”
Yup double yup !

> numerous lives it would save

If you want to save lives, work on malnutrition, reducing coal energy, water access, basic vaccines, etc. You'll have a much greater impact.

Globally around 1.3 million people are killed in motor accidents yearly and tens of millions more are permanently disabled (https://www.cdc.gov/injury/features/global-road-safety/index...). In comparison there are around 0.4 million malaria deaths annually (https://www.who.int/news-room/fact-sheets/detail/malaria). So eliminating motor accidents would save around 3x more lives than curing malaria.
This is indeed a problem, but Denmark's highways right now have 1/6 of the death rate of US highways, so if saving lives actually was the goal, AI isn't exactly the low hanging fruit.
When I was in Sweden on vacation, I was surprised that almost all except the most minor roads have a central divider. To allow overtaking, they have 2+1 lanes, and then after a few km they switch to 1+2 lanes (extra lane in the other direction).

This eliminates the most deadly accidents (head on collisions) and makes overtaking completely stress free.

It's a simple intervention that you can do almost anywhere, and it saves lives immediately. You only need to invest a bit in concrete barriers and paint.

I wonder why almost no other country does that.

I think it would be a lot easier to develop full self-driving than to get Americans to accept and implement the road safety measures that are in place in Denmark. And that's not even counting if there are cultural factors that make Danes better drivers other things being equal. I can't even imagine how many billions of dollars it would take.
What’s the point of comparing the US to countries that are as populous as the DC metro area? There are so many factors at play the comparison is completely meaningless.
> So eliminating motor accidents would save around 3x more lives than curing malaria.

Indeed, a worthwhile intervention. But when do you think Tesla will be auto-updating the FSD rickshaws in Liberia?

The faster it gets solved in the first market the faster it gets solved in the last, so the point stands.
There’s also the time spent not driving. That counts as part of a life saved for every commuter
You could also achieve this with a bus.
If we just look at deaths then sure, this could be right. However malaria is something we know how to tackle and isn’t that expensive. It’d be much more efficient to cure malaria than to eliminate all motor accidents.
These are political problems, it's a different skillset.
How can we get jobs in these areas or do you mean to start businesses in these areas?
I'm sure there will be a ton of residual effects from FSD. One off the top of my head being Emergency Services will be able to respond to emergencies faster because of minimized road congestion.
History has shown that when you make driving easier, people drive more.
And? Does that matter if we have better capacity/congestion planning because all the cars are self driving. There's so much wasted time in traffic and excess congestion because humans are at the wheel creating chaotic traffic fluctuations by their driving.
Nope. The best minds work on whatever they're interested in (this includes making better ads):

https://ai.facebook.com/research

https://research.google/research-areas/

That’s definitely not true. The smartest (clearly not the best if you take conscience into account) minds of today work either in ad farms or as money movers. You can sugarcoat it however you want but if you work in google or Facebook you definitely are just farming ads but with extra steps.
Hinton and Lecun are two of the smartest people working at Google/FB, and they don't work in ad farms or as money movers.
Not directly but their work needs to benefit an ad company to be allowed to continue.

Or else it exists in some intersection of corporate benevolence and the work not actively harming the ad company. Which is just not an arrangement I trust sorry.

Plus I mean that's two people. How many people work at google and fb and how many who do get to decide they're going to do something more important than ads?

Maybe in tech, but not in bio.
Or nearly any other field, e.g., mechanical engineering, electrical engineering, chemistry/chemical engineering, nearly any of the sciences involved in the medical field (from pharmacology to psychology to name a few). Even "softer" fields like law and literature have present day geniuses pioneering new ground.

I understand that HackerNews is tech centered, but some times when I read "the best minds of my generation are doing X" I wonder if the commenter can see the flashes of brilliance shining beyond their field or what they know as "tech."

I just flicked through a few job ads on the career page of Google Research. All of them describe fundamental research oriented towards improving the commercial services of Google. It is very far from pursuing whatever one is interested in.
If you are one of the smartest people on the planet, you can work on whatever you're interested in. You can, if you want to, work on fundamental research at Google without any direct connections to commercial services of Google. Just look at their publications.
> it is far more interesting than 90% of the stuff a lot of your FAANG companies are spending R&D dollars on

It’s not really about interesting for most people, it’s about is there a market for this and ultimately can I pay my mortage with this? I’m all for noble pursuits but don’t put down the trillion dollar smartphone, social media, PC markets that have long established themselves for the product we don’t even know is possible yet

> It’s not really about interesting for most people

This is an absolutely ludicrous statement. A very large number of people absolutely do prioritize what is interesting to them when it comes to their career. No one is going to be dirt poor, busking on the streets to make ends meet because they decided to work on self-driving tech. Nor is Tesla in any dire situation that they can't afford to fund their well-paid team of 20-25 ML engineers.

> It’s not really about interesting for most people, it’s about is there a market for this and ultimately can I pay my mortage with this?

This is so asinine. Just because some R&D project is the most profitable thing FAANG companies can invest in doesn't mean it's actually the best allocation of resources for the people working on it.

Market fundamentalism is a brain disease.

> it’s about is there a market for this and ultimately can I pay my mortage with this?

I am sure Tesla employees can pay their mortgages.

I think Karpathy at Tesla has basically unlimited funding, Tesla is developing custom hardware. They've already deployed said hardware in the wild, and they're probably about as close to Waymo to true full self driving. We also don't know what his pay situation is, but I wouldn't be surprised if he had multimillion dollar bonuses tied to various milestones. I know if I were Elon Musk, I wouldn't want to lose the guy.

So sure, he could leave, but to do what? To start building something similar from scratch somewhere else? He could go to Waymo to find that he went from being the project leader to an underling, and that Waymo is not using the approach he wants to use (he designed the Tesla project, and it's close to pure deep learning). IMO, unless something goes really wrong at Tesla, he will stay, because they're so close to success, surely he wants to see what happens, because the payout will be huge.

> I think Karpathy at Tesla has basically unlimited funding,

Tesla's R&D spending in their earnings report was ~1.5 billion. That's a small number for unlimited. To contrast, their competitor at GM, with a significantly smaller market cap, is spending 6.2 billion.

> They've already deployed said hardware in the wild, and they're probably about as close to Waymo to true full self driving

Can you cite a source for this? Tesla is "probably about as close to Waymo to true full self driving" is an absurd claim. Waymo publicly states they're at level 4 autonomy (https://twitter.com/Waymo/status/1347286935535017986). Tesla states they're at level 2 autonomy (https://www.autoblog.com/2021/03/09/tesla-full-self-driving-...).

> and they're probably about as close to Waymo to true full self driving

Absolutely no one actually working on the autonomous side of the automotive industry, myself included, believes this. Tesla is around the middle-bottom of the pack in terms of actual driverless operating capabilities. They're at the top of the pack only in marketing and reckless deployment before the tech is ready.

If you work for a competitor, you are clearly biased. Show us some evidence, some uncut videos of GM's Cruise or whoever besides Waymo you believe is ahead of Tesla.
Waymo presumably also has custom AI hardware from their parent co. (TPUs). Also their own custom lidar hardware.
Are TPUs designed for low-power applications? You don't want to burn lots of power in an electric car.
They have both high precision training TPUs and low-precision low-power edge-TPUs.
I'd actually say they're closer than Waymo to FSD, given that Waymo's solution relies on much more expensive tech and high fidelity 3D mapping. To my mind you're not true FSD until your car can drive literally anywhere an average human could, and I'm not sure that's possible with Waymo's solution until they've mapped the entire world.
You don’t get to be closer to FSD just because you have a grander vision of driving everywhere a human could. They have to actually demonstrate it. It’s been years and Tesla still doesn’t have the confidence to let drivers take their hands off the wheel.. you know, the true test of self driving. So how exactly are they close?
I didn't say "close", I said closer. Full self-driving (e.g. "Level 5") is driving everywhere a human can. I have doubts that Waymo will ever get to Level 5 without 3D mapping the entire world, which (to me) sounds like a somewhat intractable problem. There is a lot of world, and it is constantly changing.

The problem here is the "level" system everyone has been told is the standard, which heavily implies that if you're at "3" while someone else is at "2", then you're closer to "5". This isn't really true though because solutions at Level X don't necessarily scale/work at Level Y. I dislike using the level system for this reason.

I think Tesla is closer because they are certainly getting there[1], and I believe their model (relying entirely on CV) is the one that has the greatest likelihood of stretching to FSD (Level 5 autonomy). Mostly because there is only one system we're aware of that can achieve FSD (humans), and the sensory package there is entirely visual.

> I have doubts that Waymo will ever get to Level 5 without 3D mapping the entire world

Waymo is not trying to get to L5 at all. They are a strictly L4 technology and their focus is clearly on servicing where the market is, metropolitan cities.

L5 is a pipe dream for anyone; it's a moving target no one can ever reach. It essentially means the car can drive anywhere, in all conditions and without the driver needing to take over at all. So it really means Tesla can't declare FSD as "done" until it works for everyone, everywhere and in every condition. How close do you think they are for that to happen? Does that also mean if it encounters a unique situation and gives up, their L5 claims fall flat? Given their current poor performance [1], they have a long way to go to even let drivers take their hands off the wheel, so I'm not holding my breath here (vision stack or not).

The real end game for self driving is L4 because that's what you can reasonably promise to your users. That it works in a defined, tested area and when required conditions are met. This is why literally every SDC company is L4-only, they never promise L5. Either Tesla is focusing on the wrong problem instead of providing value to its paying customers or they are blatantly misleading customers by promising "L5 by the end of the year" every year.

I agree that Tesla dropping FSD would take a while. In addition to the huge sunk-cost and investor expectations, they have an entire strategy (via 3 year vehicle leases which are currently offering no-buyout for customers at termination) of monetizing leased vehicles as robo-taxis.

Not saying they will succeed here, but just saying that to give up on FSD would be corporate suicide at this point.

Ever since I learned that Musk didn't found Tesla [0] or PayPal [1] I get really uncomfortable when reading news like this. It's clearly Musk doing another hostile take over of a company someone else started.

[0] https://en.wikipedia.org/wiki/Tesla,_Inc.#Founding_(2003–200...

[1] https://en.wikipedia.org/wiki/PayPal#Early_history

Hostile takeover seems like a stretch. Generally you use that phrasing when someone takes over a company in order to kill it and loot its corpse, not "invest heavily in the company and make it one of the most successful in the world".

A borderline non-sensical accusation w.r.t. PayPal, since he definitely didn't takeover PayPal, he founded X.com and got a payout through that after the merger and subsequent IPO + acquisition by eBay.

For Tesla, he was the first investor and took an active role in the company, starting in 2004 – less than a year after its inception and four years before they produced their first car (the Roadster). By the time the Roadster actually hit production, he was the CEO. Was the Roadster (a Li-ion sports car) Eberhard's idea? Absolutely. But it seems very unclear that it actually would have existed if not for Musk. And the rest of Tesla's vision/direction (that has made it the world's most valuable tech company) seems to have come almost entirely from Musk.

He wholly founded SpaceX and they're doing pretty well.

> Generally you use that phrasing when someone takes over a company in order to kill it and loot its corpse,

You may be thinking of a leveraged buyout or LBO.

A hostile takeoever is one where the management of the company are excluded from acquisition talks. The potential acquirer goes over their heads and proposes a deal with the shareholders directly.

An LBO is a type of hostile takeover. In either case, the motivation from the "aggressor" is not typically "gee I just really want this company to succeed".

In any case, I certainly don't think Musk's relationship with Tesla qualifies.

I mean tesla without Elon is not really tesla. I never really thought he FOUNDED PayPal, but rather part of the so-called PayPal mafia that was successful at starting other companies. I never heard that he didn’t pull his weight from Peter thiel or the others
I can't find a source right now, but I remember reading about that Elon Musk tried to fight for Paypal to use Microsoft software instead of Linux when he became the CEO after the X.com merge. Since Paypal wanted to continue using Linux (who wouldn't?) they instead switched CEOs.

Edit

> I never heard that he didn’t pull his weight from Peter thiel or the others

I don't know. A letter of no-confidence to the board in order to replace Musk with Thiel doesn't exactly shine a lot of good light on Musk. From https://www.cnbc.com/2019/11/02/why-elon-musk-says-taking-va...

> At the time, he was CEO of X.com, and company executives were not pleased with his leadership. While Musk was on the plane with Justine, executives delivered a letter of no-confidence to the company’s board, pushing Musk out as CEO, and replacing him with Peter Thiel.

As a big linux fan, Microsoft probably was the better choice 20 years ago.
As a Linux and Microsoft user for more than 20 years and dealing with hosting 20 years ago, I can say Microsoft was absolutely not the better choice.
2000 was the year of Windows 2000 and Windows ME. Did you ever use those in a professional capacity at the time? I think if you did, you wouldn't say you're a big Linux fan _and_ advice a company to use Windows. Or maybe we simply have different definitions of what a "fan" means.
I was more thinking in terms of what you could readily hire programmers for around that time. Definitely did not mean to imply that Windows was the actual better tech stack, just that for various business reasons going with Microsoft may well have been a better choice.

Though in regard to tech stacks, I also thought X.com might've been using .NET and (if that had been the case) then to my mind it was the better option, compared to what many people were using for scrappy Linux web backends in that era – PHP (which I say as someone who wrote his first web backend in PHP). But after looking up the timelines, I realize that this wasn't the case. Musk was replaced as CEO in 2000 and .NET was released in 2002.

This is also 20 years ago.
How does that change the fact that the statement was "he didn’t pull his weight from Peter thiel" and it seems that he meaninglessly fought existing culture and also was ousted, which seems to indicate that he did in fact not pull his weight according to the board?
I only wish I was slightly older during the dot com boom. I had to finish college and do it with flying colors, being from a poor family. If you had the means and some padding to take fairly reasonable risks, you walked away with riches. These people were at the right place and the right time, let's not lionize them as investment geniuses. They had money to put down on some horses, that is ALL.
That doesn’t line up with what I’ve read about that time period. A lot of the companies that were well funded by such bets went bankrupt. In all likelihood you would have lost money during the bust. The companies that weathered the storm were actually delivering good products and had cash flow. That takes a lot of work on the tech and business sides.

Maybe you could have timed the bubble and exited with a pile of cash, who knows. If you want to make those kinds of bets you could make them right now.

The far more common scenario in the dot-bomb era was that you lost your job (which almost certainly wasn't paying the kind of salary many developers expect today), were left with a pile of worthless stock options, and maybe spent a couple years asking people if they'd like fries with that. (That's only a slight exaggeration. I was very very lucky to almost immediately land another position--which then went through its own rough times but not to the point of being unemployed.)

Some people made out of course, but in general ~2001-2004 was not a great time to be in tech.

For this specifically, Musk was so immature and inexperienced that he was either kept away or removed from higher posts, but since the ideas themselves materialized and were successful (see Zip2. X dot com), he walked away with millions. He was the definition of failing upwards. And once you have 200 bars of walkaway money, it's really, really hard to fail.

Per Wikipedia: "Within the merged company [PayPal], Musk returned as CEO. Musk's preference for Microsoft software over Linux created a rift in the company and caused Thiel to resign. Due to resulting technological issues and lack of a cohesive business model, the board ousted Musk and replaced him with Thiel in September 2000."

Having been there as an adult, I can say right now is a far better time to walk away with riches. There were a lot of scams that made scammers money, but very few made real money if they were legitimately trying to build a business.
I agree with that. Certainly there were lottery winners who got in on the ground floor of ultimately very successful companies. And there were others who had disposable income who bought into companies like Yahoo early and got out in time.

But, in general, salaries were mostly unexceptional in tech even in Silicon Valley, a lot of companies went bust, and even most of the surviving firms--including the big systems/storage/chip/networking/etc. players--went through some very lean years with a bunch of layoffs.

True. I think there are more lottery winners today, but we know the names of the previous generation more.
It was certainly no sure thing, and it’s easy to say that in hindsight. There were definitely a lot of people who walked away from the dot-com era with worthless stock options and wounded egos. Plenty of people ended up taking the “safe” route too and getting a job at IBM.

We’re in the same place with crypto right now. People will look back and say “oh jeez if only”. The early bazillionaires are already minted but there are a lot of crypto millionaires made every day. It’s just a lot of people dumping their life savings into BTC/ETH and enjoying the ride.

Hindsight makes history look easy and obvious. It is far from the truth.
There's a strong survivorship bias in what you hear about. A few hundred folks made solid money, but many, many more had to go hunting for jobs after the bubble burst.
It was an exciting time in other ways, but not for making money.
Paypal was a merger between confinity payments and musks x.com
Perhaps a cliched comparison, but Adolf Hitler didn't found the NSDAP either.
I really wouldn't go far based on that list. It's mostly from the Waitbutwhy article from years ago when they were still basically a research/brainstorming group and hadn't even figured out what they wanted to do or what approach they wanted to take.

For comparison to Musk's other companies , it's analogous to Bill Cantrell or Mike Griffin or that guy from sea launch at SpaceX.

Some in this group were very briefly there like Tim Hanson.

Some I think are misreported to not be there , unless anyone has any extra information. For example , Paul Merolla was there at the last conference , even though he's reported as not being with the company.

Some I think are also advisors like Sabes , unless something has changed.

One of them is just a neurosurgeon , but they already have a whole surgery department with a lead now.

Am I imagining it, or have scientists across the board left lots of AI startups recently? OpenAI just had a big split too where a bunch left.
Yeah but in a lot of cases it's because money (especially AI fundraising money) is hella cheap and it's far more profitable (like, 10-100x) to co-found their own AI startup than to play senior scientist for someone else.
Capitalism truly is the most efficient way to allocate resources. ;)

Less snarky response, perhaps if we saw more worker coops we'd care less about being a founder and more about delivering a result.

Nothing in AI would pay a cent to a worker coop, because revenues are very small right now, it's all "potential".

So even though the expected value is (correctly, in the medium term, IMO) super high, everyone would get nothing based on current or near term revenues, which is exactly the situation VC exists to rectify. What you're seeing is the free market working correctly as more founders jump in to take VC money and make bets on their ability to execute.

Well, a "mostly worker coop" in the sense of a company that takes capital from elsewhere but where shares are otherwise spread out among the workers could still work as a VC funded company as long as they addressed the issue of how to make it possible for that VC to get an exit. It becomes easier to get to a middle ground the cheaper it becomes to take capital.

Interestingly one of the things Marx and Proudhon violently agreed on was that cheap credit is one of the most radical things you can create. The reasoning is simple: The cheaper credit is, the less power employers have over employees. To take a hypothetical extreme: if credit is free and guaranteed, an employee can walk out at any point and take whatever time they need to figure out what to do, at which point employer power of employees is nullified.

As such, at some point along a gradient of cost and access - and it may well be an impossible point to reach - capitalism becomes indistinguishable from socialism, in that capital ownership becomes a matter of choice.

Start one! Everyone who mentions them should start one. Work super hard to get it started, deal with all the politics and then get voted out.
There is no capitalism at work when there is no product sold.
Why? You can sell a dream.
Nobody seriously considers 'SV investors' to be a market. That is not how people get rich, anyway.
TLDR: This technology is in its infancy but is very much so in the R&D phase. He needs to retain top scientists and avoid making promises.

The research isn't there yet, which is why Elon should be trying to retain people who have deeply studied the hippocampus and brain. What the heck is he doing? Find the best people in this domain. The potential is there with the electrode technology he's built. It's an AI problem now, to make sense of the data. Supervised learning mostly. You can measure what the brain does when certain things happen. He needs more researchers in the fundamentals. I think if they've built the robot that inserts the electrodes non-invasively, they can continue to add additional electrodes and get an even more accurate measurement of what's happening elsewhere in the brain. This tech will takes years and years to master. Neuralink a science company. Or at least, it should be at this point if I'm taking it seriously. God knows there are hundreds of tech companies selling SAAS software for domains that have negligible research. Neuralink shouldn't be like that. Don't overpromise and underdeliver just yet, causing best people to leave. This company has tons of potential.

> The potential is there with the electrode technology he's built. It's an AI problem now, to make sense of the data. Supervised learning mostly. You can measure what the brain does when certain things happen.

This is an unproven hypothesis. Since we do not know how computation actually happens in the brain, we can't say for sure that electrical signals can be matched to the actual computations happening, even if they are correlated. It is still possible that the electrical signals we are measuring are just byproducts, and that the real compatation happens at a chemical level or inside each individual neuron or even in microtubules as Penrose believed.

The nice part is that this means that neuralink's attempts could be extremely useful to our understanding of the brain even if they fail - it would actually be an amazing discovery if they could show that you CAN'T deduce the brain's intent from observing electrical activities.

We do know for sure though that you can use electrical signals to interface with motor neurons, so at least improvements in prosthetics should be something that neuralink can realistically deliver.

Even if the electrical signals that are measured are only echos of the triggering signal, it can be utilised as a control signal.

The problem comes when you want to send a signal back into the brain - but even then there's a chance that the brain could rewire itself to take care of redirecting and reprocessing the fuzzy and inaccurate input.

Reasonably accurate output has the potential to revolutionise prosthetics (feedback aside).

> Even if the electrical signals that are measured are only echos of the triggering signal, it can be utilised as a control signal.

I'm not thinking of something like echos, but more of auxiliary signals - e.g. Perhaps they are signals to increase energy supply to a particular are of the brain, or for controlling 'peripherals', while the main computation happens in other channels.

It's also an interesting question to see whether the analysis techniques could work on a simpler and clearer machine, one where we know for sure that is controlled only by electrical signals - could we infer what a CPU is doing by just measuring electric currents in various areas, without any knowledge of the code running there? This is an experiment that is eminently doable, especially if we design a core specifically for this purpose (making a large and slow core in order to focus purely on the problem of analysis, not difficulties in probing and data collection).

> It's an AI problem now, to make sense of the data.

Not a neuroscientist, but it seems like the problem is more involved than just training a DL model on a data. We need detailed maps of the brain before we put any electrodes in it. Meanwhile, full mouse brain map is likely a decade away [0]. Humans have a bigger brain, imagine how long it’d take. It’s just a lot of manual labor which takes incredibly long time. Keep in mind that you also need to map thousands, if not millions of brains to model population heterogeneity.

Getting top talents or investing on top talents? He has the money and he has the guts to take big risks which is remarkable for an investor. I think any scientist with a "revolutionary" idea that requires lots of capital will proactively approach Elon Musk.
>but with neuroscience, it seems the research isn't there yet.

The interesting aspect of your comment is in fact: what is the capital outlay and time needed for the science to actually get there.

Elon has a track record of severely under-estimating those, but he is also smart enough (via PR / govt grants / leveraging past successes, etc ...) to stretch both beyond anything reasonable, to the point of actually reaching success (e.g. TESLA, SpaceX).

Good to know, I may have to give Neuralink another try. My previous experience with the original 8 a few years ago during the hiring process was overwhelmingly negative. I'm hoping their culture has changed to be more in line with Musk's public persona since then.
Musk's public persona is a nightmare, even if you only look at his public professional persona -- encouraging overwork, getting himself knowledgeable enough about a subject to fool laymen and investors but not deeply understanding it enough to provide reasonable estimates, a total disregard for safety of both his customers and his workers, and developing an unhealthy cult of personality.

I own a Tesla, I love SpaceX, I think Elon Musk is insufferable.

> getting himself knowledgeable enough about a subject to fool laymen and investors but not deeply understanding it enough to provide reasonable estimates

This is both a strength and weakness. How many times have people wished CEOs actually knew what they were talking about? As long as Elon knows enough to build a decent team and lead it well, he doesn't need to know everything.

From the outside it looks like he sees himself as 'one of the engineers' which is something I deeply respect, even if there's major issues as well (FSD and Hyperloop being the big ones).

Yeah, I appreciate any engineering firm that at least attempts to have some engineering leadership in charge.

> major issues as well (FSD and Hyperloop being the big ones).

That Vegas loop too... That's going to be a truly awful tunnel fire someday, and the safety systems there seem seriously lacking. (Also, the whole project feels like a grift.)

It’s in a conceptual prototyping stage, jeez. Criticism is fine but you gotta let the bud flower, come to fruition and then put regulations. That’s how literally every single world changing technology is invented. If Elon’s ideas don’t work out, fine. It was a boondoggle on his own dime, what’s anyone’s business in slamming down on the efforts?

Risk taking is amazing. I’m not sure if I want to live in a risk averse world where ideas are nipped in the bud by CEOs of GE and Honeywell.

"Tunnels" is not something that is at a "conceptual prototyping stage". We've built tunnels for hundreds of years. We know what the dangers are, we don't need a prototype to kill a bunch of people to find that out.
Ah yes, the world changing technology of putting a potential fire hazard in a narrow tunnel with no escape routes. What could possibly go wrong? [1]

Those that work for him call it "the impossible ask": Musk will basically spin through the engineering floors of SpaceX and push the team for something that's functionally impossible. Whether this strategy motivates brilliance to emerge is probably not _terribly_ in dispute: they do get results. The "at what cost" element and the burnout and other impacts... those are more tricky to weigh.
I don’t get Elon hate just the way I don’t get fanboyism and cult following. Neither side provides an objective and truthful representation of reality.

No single personality can be 100% perfect. Let’s not ignore pretty much the entire world changing revolution of EVs and reusable rocketry, while focusing on the guy’s public persona and how he behaves that’s apparent to us and project what he must be like in general. Seems deeply and profoundly unfair.

Why can’t someone have flaws which is ok to point out, but then ignore their accomplishments. Opposite also stands! Fanboys of Elon think he is some kind of a messiah to save the world from global collapse but turn a blind eye to his rather rude behavior?

It’s like populism has a reverse backside of the coin.

IMO silent majority has pretty balanced view of him and just doesn’t care to participate in a holy war praising or hating on the guy. Social media and regular media bias towards the polar opinions, as with anything else.

History respects Edison, Jobs, Tesla, Carnegie, Rockefeller, Hughes for what the accomplished while acknowledging their individual flaws. I think Musk will be remember similarly. Depending how successful his ventures are over the coming century he might even be remembered more than any of them.

It's an interesting observation. Personally, when I look back at giants and read their biographies, I find the most interesting bits usually about how they were motivated, what drove them, how they overcame challenges and hopelessness, how they forged business relations - I think the least interesting part is their personal life and what they did to piss someone off or what they tweeted/told publicly. The latter is just typical soap opera of details that provide little value to me. The latest Steve Jobs movie primarily focused on the melodrama of his personal relationships and offered literally nothing about what made Apple succesful.
Can I say, it's really refreshing to see your list of very apt comparisons to very smart and successful people. Many tech-heavy news sites (looking at you ArsTechnica) compare Musk to Newton and Einstein.
To me, Musk's flaws are much smaller than some of the others you mention. Namely: overly optimistic (some would say fraudulent but eh) timelines, a puerile sense of humor, and calling that diver a pedo.
It in response to a post in which the author said they wanted to revisit joining Neuralink because hopefully now their culture is more in line with Musk’s public persona. And the post ended with praise for Musk’s projects.

That doesn’t read as “haters gonna hate” to me, but rather as a narrow criticism of just the one aspect of Musk’s businesses that was brought up.

> Let’s not ignore pretty much the entire world changing revolution of EVs

Elon sure did. He decided, apparently out of pure greed, to invest big into Bitcoin, driving the price up and with it increasing the carbon emissions of it, enough to quickly wipe out basically all carbon savings Tesla has worked to achieve for its entire company lifetime.

Bitcoin can be entirely powered by (renewably sourced) electricity.

Our current financial system cannot.

It can, and when it does, it destroys that energy, and forces other users to use polluting energy.

The environmental cost of Bitcoin is not that of the energy it uses, it is the cost of the dirtiest energy it forces others to use.

" a total disregard for safety of both his customers and his workers"

At least in the case of SpaceX, they do not seem to be as reckless as you paint them. After 20 years in space industry, they have 0 fatalities on record, which is uncommon for a corporation of this size and history.

And they scrub launches whenever they are concerned about weather or anything off-nominal that their sensors indicate. Which led to an excellent safety record for Falcon 9s once the technology matured.

Gwynne Shotwell runs the day to day at SpaceX.

She hasn’t gotten a ton of press but it’s clear she is a key reason for the successes you described above.

Which Musk can take some credit for—-hiring well and not getting in her way.

> not deeply understanding it enough to provide reasonable estimates,

Reasonable estimates like what ? If your company works on something that has never been done before there is not much data at hand to make good estimates is it ?

I have so many colleagues with that sentiment who give terrible plans because ¯\_(ツ)_/¯ it’s research. They mostly talk about timelines for the big end goal pie in the sky, and they’re generally wrong. That was me when I was more junior.

I also have colleagues who promise small concrete incremental deliverables in predictable timelines. They rarely talk concretely about the big end goal pie in the sky’s timeline, but generally deliver the big thing sooner anyways.

The answer isn’t making reasonable estimates of an inestimable thing, it’s providing reasonable estimates for the reasonably estimable pieces. Instead of “we’ll have ultra mega science in three to five years!” it’s, “we’ll have this specific piece of the stack built by 2022 and we hope it’ll enable these other slightly less concrete things towards ultra mega science.”

Sadly, this is great for the actual working condition and environment, but nothing that attracts funding.
Fundraising isn’t some magical situation where bad behavior is suddenly acceptable because it works, but I understand your point.
The point is Elon knows exactly whether estimates are achievable or not, but does it anyways.

There is a reason why legally Autopilot/FSD is a driver-assist system, but for marketing purposes robotaxis are just around the corner.

There is a fine line between 'overly optimistic' and misleading, and more often than not, Elon crosses the line.

See https://elonmusk.today/ for an overview (if a bit biased).

Everything from self driving, to shipping cars, to moon and Mars missions. It's one thing to be an optimist. It's another to promise something you have no path to deliver.
SoaceX just got a sole-source contract with NASA to send humans to the moon in 3 years.
Musk said he'd be launching a mission to Mars every possible window starting 2024. Including manned missions. I believe he was going to send an experimental mission to Mars before that.

My point isn't that these companies don't get there, it's that they take much, much, much longer than estimated.

I agree with self driving... But Tesla IS shipping a heck of a lot of cars, now. And sending people to the Moon and Mars seem increasingly likely.
Yes, now they are. Tesla circa 2014 was very different.
Fair points, but one trait that I do admire is his lack of elitism. That was sorely missing at Neuralink when I visited.
Yeah he really fooled all those Tesla and spacex investors into those massive returns. They must be so pissed.
They might not be but the TSLAQ people are still chomping at the bit.
> but not deeply understanding it enough to provide reasonable estimates

There are enough senior software engineers in this world that will have a crazy hard time making a good estimate. There was this HN comment once that mentioned that learning how to estimate work is it's entire own discipline.

It can be done and trained, according to that comment, but the comment also seemed to imply that it seems very unusual to do so.

I can't find the comment unfortunately, I read it years ago here.

Elons estimates aren't about being accurate.
Musk’s public persona is: the guy without whom nobody would know the names Tesla and SpaceX. As noxious as his personality seems to be, he does deliver.
Zoox is very much still doing self driving...
