It's time to jump on the train. I'm a cranky, old, embedded SWE and claude 4.5 is changing how I work. Before that I laughed off LLMs. They were trash. Claude still has issues, but damn, I think if I don't integrate it into my workflow I'll be out of work or relegated to work in QA or devops(where I'd likely be forced to use it).

No, it's not going to write all your code for you. Yes your skills are still needed to design, debug, perform teamwork(selling your designs, building consensus, etc), etc.. But it's time to get on the train.

[friendzis]

The moment your code departs from typical patterns in the training set or ("agentic environment") LLMs fall over at best (i.e. can't even find the thing) or do some random nonsense at worst.

IMO LLMs are still at the point where they require significant handholding, showing what exactly to do, exactly where. Otherwise, it's constant review of random application of different random patterns, which may or may not satisfy requirements, goals and invariants.

[kakacik]

A contrarian opinion - I also didn't jump the train yet, its even forbidden in our part of company due to various regulations re data secrecy and generally slow adoption.

Also - for most seasoned developers, actual dev activity is miniscule part of overall efforts. If you are churning code like some sweatshop every single day at say 45 its by your own choice, you don't want to progress in career or career didn't push you up on its own.

What I want to say - that miniscule part of the day when I actually get my hands on the code are the best. Pure creativity, puzzle solving, learning new stuff (or relearning when looking at old code). Why the heck would I want to lose or dilute this and even run towards it? It makes sense if my performance is rated only based on code output, but its not... that would be a pretty toxic place to be polite.

Seniority doesn't come from churning out code quicker. Its more long the lines of communication, leading others, empathy, toughness when needed, not avoiding uncomfortable situations or discussions and so on. No room for llms there.

There have been times when something was very important and my ability to churn out quick proof of concept code (pre AI) made the difference. It has catapulted me. I thought talking was all-important, but turns out, there's already too much talk and not enough action in these working groups.

So now with AI, that's even quicker. And I can do it more easily during the half relevant part of meetings, which I have a lot more of nowadays. When I have real time to sit and code, I focus on the hardest and most interesting parts, which the AI can't do.

[friendzis]

> ability to churn out quick proof of concept code (pre AI) made the difference. It has catapulted me. I thought talking was all-important

It is always the talking that transitions "here's quick proof of concept" to "someone else will implement this fully and then maintain". One cannot be catapulted if they cannot offload the implementation and maintenance. Two quick proof of concept ideas you are stuck with and it's already your full capacity. one either talks their way out to having a team supporting them or they find themselves on a PIP with a regular backlog piling up.

[morshu9001]

Oh they hired some guys to productionize it, who did it manually back then but now delegate a lot of it to AI.

[01100011]

Your comment is basically paraphrasing my responses to older threads on HN telling me I needed to use vibe coding.

Most of my day isn't coding. But sometimes it is. On those days, AI helps me get back to doing the important stuff. Sure, I like solving problems and writing code, but where I add value to my company is in bringing solutions to users and getting them into production.

I'm a systems/embedded engineer. In my 30 years of being employed I've written very little code, relatively speaking. I am not a code monkey cranking out thousands of lines per day or even week. AI is like having an on-demand intern who can do that if I need to, however. I basically gained an employee for free. AI can also saving me time debugging because look, I'm old and I really don't write all that much code. I mess up syntax sometimes. I can't remember some stupid C++ rule or best-practice sometimes. Now I don't have to read a book or google it.

AI is letting me put my experience and intuition to work much more efficiently than ever before and it's pretty cool.

[aswegs8]

While I think that is true and this thread here is about senior productivity switching to LLMs, I can say from my experience that our juniors absolutely crush it using LLMs. They have to do pretty demanding and advanced stuff from the start and they are using LLMs nonstop. Not sure how that translates into long term learning but it definitely increases their output and makes them competent-enough developers to contribute right away.

[friendzis]

> Not sure how that translates into long term learning

I don't think that's a relevant metric. "learning" rate of humans versus LLMs. If you expect typical LLMs to grow from juniors to competent mids and maybe even seniors faster than typical human, then there is little point to learn to write code, but rather learn "software engineering with artificial code monkey". However, if that turns out to not be true, we have just broken the pipeline producing actual mids and seniors, who can actually oversee the LLMs.

they might be poor at it, but if you do everything you specified online and through a computer, then its in an LLMs domain. If we hadnt pushed so hard for work from home it might be a different story. LLMs are poor on soft skills but is that inherent or just a problem that can be refined away? i dont know

[friendzis]

> What I want to say - that miniscule part of the day when I actually get my hands on the code are the best.

And if you are not "churning code like some sweatshop every single day" those hours are not "hey, let's bang out something cool!", it's more like "here are 5 reasons we can't do the cool thing, young padawan".

[reactordev]

This has not been my experience as of late. If anything, they help steer us back on track when a SWE decides to be clever and introduce a footgun.

[erichocean]

Same, I have Gemini Pro 2.5 (now 3) exclusively implementing new designs that don't exist in the world and it's great at it! I do all the design work, it writes the code (and tests) and debugs the thing.

I'm happy, it's happy, I've never been more productive.

The longer I do this, the more likely it is to one-shot things across 5-10 files with testing passing on the first try.

[wiz21c]

> The moment your code departs from typical patterns

Using AI, I constantly realize that a-typical patterns are much rarer than I thought.

[butlike]

Yeah but don't let it prevent you from making a novel change just because no one else seems to be doing it. That's where innovation sleeps.

[wiz21c]

I was meaning: even if I do somehow "advanced" stuff that not many people do, much of it is pretty common.

Humbling.

[concats]

I don't think anyone disagrees with that. But it's a good time to learn now, to jump on the train and follow the progress.

It will give the developer a leg up in the future when the mature tools are ready. Just like the people who surfed the 90s internet seem to do better with advanced technology than the youngsters who've only seen the latest sleek modern GUI tools and apps of today.

[endymion-light]

Quite frankly - the majority of code is improved by integrating some sort of pattern. a LLM is great at bringing the pattern you may not have realized you are making into the forefront.

I think there's an obsession, especially in more veteran SWEs to think they are creating something one of a kind and special, when in reality, we're just iterating over the same patterns.

[rafaelmn]

This was true since Claude Sonnet 3.5, so over a year now. I was early on the LLM train building RAG tools and prototypes in the company I was working at the time, but pre Claude 3.5 all the models were just a complete waste of time for coding, except the inline autocomplete models saved you some typing.

Claude 3.5 was actually where it could generate simple stuff. Progress kind of tapered off since tho, Claude is still best but Sonnet 4.5 is disappointing in that it does't fundamentally bring me more than 3.5 did it's just a bit better at execution - but I still can't delegate higher level problems to it.

Top tier models are sometimes surprisingly good but they take forever.

[lomase]

This was true since ChatGPT-1, and I mean the lies.

[rafaelmn]

Not really - 3.5 was the first model where I could actually use it to vibe through CRUD without it vasting more time than it saves, I actually used it to deliver a MVP on a side gig I was working on. GPT 4 was nowhere near as useful at the time. And Sonnet 3 was also considerably worse.

And from reading through the forums and talking to co-workers this was a common experience.

[01100011]

Up until using claude 4.5 I had very poor experiences with C/C++. Sure, bash and python worked ok, albeit the occasional hallucination. ChatGPT-5 did ok with C/C++ and fairly well with python(again having issues with omitting code during iterations, requiring me to yell at it a lot). Claude 4.5 just works and it's crazy good.

[mattmanser]

It's just not true, it is not ready.

Especially Claude, where if you check the forums everyone is complaining that it's gone stupid the last few months.

Claude's code is all over the place, and if you can't see that and are putting it's code into production I pity your colleagues.

Try stopping. Honestly, just try. Just use claude as a super search engine. Though right now ChatGPT is better.

You won't see any drop in productivity.

[bratbag]

It's not about blindly accepting autogenerated code. Its using them for tooling integration.

Its like terminal autocomplete on steroids. Everything around the code is blazing fast.

[IshKebab]

This is far too simplistic a viewpoint. First of all it depends what you're trying to do. Web dev? AI works pretty well. CPU design? Yeah good luck with that.

Secondly it depends what you're using it for within web dev. One shot an entire app? I did that recently for a Chrome extension and while it got many things wrong that I had to learn and fix, it was still waaaaaay faster than doing it myself. Especially for solving stupid JS ecosystem bugs.

Nobody sane is suggesting you just generate code and put it straight into production. It isn't ready for that. It is ready for saving you a ton of time if you use it wisely.

[mattmanser]

I'd say it was pretty naunced. Use it, but don't vibe code. The crux of the issue is that unless you're still writing the code it's too hard to notice when Claude or Codex makes a mountain out of a mole hill, too easy to miss the subtle bugs, too easy to miss the easy abstractions which would have vastly simplified the code.

And I do web dev, the code is rubbish. It's actually got subtle problems, even though it fails less. It often munges together loads of old APIs or deprecated ways of doing things. God forbid you need to deal with something like react router or MUI as it will combine code from several different versions.

And yes, people are using these tools to directly put code in. I see devs DOING it. The code sucks.

Vibe coded PRs are a huge timesink that OTHER people end up fixing.

One guy let it run and it changed code in an entirely unrelated part of the system and he didn't even notice. Worse, when scanning the PR it looked reasonable, until I went to fix a 350 line service Claude or codex had puked out that could be rewritten in 20 lines, and realized the code files were in an entirely different search system.

They're also generally both terrible at abstracting code. So you end up with tons of code that does sweet FA over and over. And the constant over engineering and exception handling theatre it does makes it look like it's written a lot of code when it's basically turned what should be a 5 liner into an essay.

Ugh. This is like coding in the FactoryFactoryFactory days all over again.

[iammrpayments]

I don’t use AI for anything except translations and searching and I’d say 3 times out of 10 it gives me bad information, while translation only works ok if you use the most expensive models

[lomase]

I am an old SWE and claude 4.5 has not changed a thing on how we work.

The teams that have embraced AI in their worlflow have not increased their output compared with they ones that don't use it.

[wiz21c]

I'm like you. I'd say my productivity improved by 5-10%: Claude can make surprinsgly good code edits. For these, my subjective feeling is that claude does in 30 min what I'd have dont in one hour. It's a net gain. Now, my job is about communicating, understanding problems, learning, etc. So my overall productivity is not dramatically changing, but for things related to code, it's a net 5-10%

[dangus]

Which is where the AI investment disconnect is scary.

AI Companies have invested a crazy amount of money into a small productivity gain for their customers.

If AI was replacing developers it wouldn’t cost me $20-100/month to get a subscription.

[lomase]

If I had something that could replace developers I will not sell it.

I will get all the goverment IT contracts and make billions in a few months.

Nobody does it because LLMS are a fucking scam, like crypto, and I am tired of pretending is not.

[01100011]

Two things I solidly recommend it for are helper scripts and test code. Writing boilerplate tests is so much easier with it. I recently vibe coded an entire text-ui frontend to perforce, similar to tig for git, and it took about 2 hours. Yeah, I'm not ready to use it for our driver code yet but I would use it to check my work.

[oblio]

What you're doing there with Perforce sounds like procrastination to me.

Good for you, though.
