They use a tunnel boring machine to bore a tunnel with a 45° slope.
They do go into the mechanics of how they make this insanely massive machine drive up a grade that steep, and how they ensure it doesn't slide backward.
I was glued to the screen more than with most movies.

The boring company isn't move fast and break things. They literally just bought a drill and use it like any other construction company. There's no innovation at all.
They started that way, just buying a drill, but are now trying to innovate and build their own one. They are just starting using Prufrock-3. The Prufrocks are machines the Boring company have made themselves. They say "Prufrock's medium-term goal is to exceed 1/10 of human walking speed, which is 7 miles per day." which is way faster than anyone else. The Swiss machine in the video did 400m in 4 months. They are also experimenting with evacuated tunnels (https://youtu.be/nV07jqwCy0A?t=879) which may not go anywhere but is at least an attempt at innovation.
"7 miles per day" is all talk and no proof it can actually be done. The Swiss dig a lot of holes from easy to very complex terrain. If there was an easy way go that much faster they would.
There was a derailment of a cargo train the the Gotthard base tunnel last year [1]. It caused a huge amount of damage and one tunnel will be close until September this year. They need to replace 7km of track. If there way anyone to do this correctly faster they would as it is costing millions not having this route open. Concrete needs time to cure etc. some things you can't just make faster because someone said so.
It’s incredible how defensive people get around others’ ambitious goals.
Every Elon company sets super high goal targets. They are often completely unrealistic with current technology but it inspires certain types of people to innovate and it works quite well.

Nobody said anything about “easy”. Also, The argument of “the established players don’t work on X so X isn’t possible” doesn’t work.
If the Swiss are happy with their industry the industry isn’t going to risk really capital intense experimentation to do better. See: Innovator’s dilemma

No, a lot of the time the machine was stationary because the needed to manually reinforce what they were about to drill through, so the machine wouldn't get trapped and buried in gravel. Wouldn't Prufrock-3 be similarly slowed down!
In addition to that I assume that the 7 miles a day claim assumes 24/7 drilling, whereas I wouldn't be surprised if the swiss were doing 8/5 drilling.
Nobody said “break things”. Making one specific thing reliably, quickly and cheap is a completely different approach to the “move fast and break things” approach.
Fast. Fast always wins. Trying something, regardless of outcome teaches something about the world. The more trials, the more you roll the dice, the more you learn.
I really hate being wrong, but it is much better to be wrong a lot, and quickly understand why. The alternative is to try nothing. It’s kinda sad.
Fast wins for something like mobile apps but not infrastructure where safety matters and you can’t just shrug off liability. The Boring Company is a great example: fast to market themselves but almost all of their projects have fallen through.
Which nascent technologies have became common, dominant by innovators unilaterally adhering to the precautionary principle?
The cliché "Worse is better" describes this (turrible) phenomenon. (The flip side being "safety regulations are written in blood.")
I really wish this wasn't the world we live in. I want to live in a world with consequences (and justice). I've been railing against it my whole career. And judging from my meager savings, failing in my efforts.
Iteration always wins. There may be other constraining factors, but if you can violate those to iterate more (i.e. cheat), you’ll beat your competitors who honor those constraints.
This has nothing to do with the success or failure of any given company.
It does depend on the domain though. Sometimes moving slowly and carefully can result in a faster successful outcome than throwing shit at a wall and seeing what sticks.
> The more trials, the more you roll the dice, the more you learn.
If you have infinite dice rolls this is obviously true. If every dice roll costs you something or indeed everything... heh. Maybe don't just roll it to see what happens?
Yes, sure fast wins when building a bridge. Or a tunnel. Which then collapses. Safe wins, this is not Facebook where people share some holiday pictures.
"but it is much better to be wrong a lot"
I disagree, "Oh the bridge collapesed, I was wrong! But this is much better than being right" - Nope.
... which has its own reasons, namely regulations (you know, every time there was a new disaster they added another one) or maybe some corruption. You don't see bridges falling in US regularly killing tons of folks, do you.
I am not saying its ideal and there is no room for improvement, nothing in real world is, but please consider other, 'fast' scenarios for long term (100+ years) existence when not only many lives are at stake.
