Generally building something is not about "What does this teach us?" but rather "What can this be used for?". You don't build a house and as "What does this teach us?". It's honestly almost a perverse question to primarily ask for something that aims to have practical value.
The clear reason this has worth is that it's much faster than TSC.
I guess I’m just perverted then.
That's why the commenter said

Then they asked if it teaches something because it is a risky utility to them. You're trying to make it sound a lot weirder.
HN is going to be a weird place to be between people loving AI and the loss of loving tech. I don’t remember last time I watched a good tech dev video. At least the video game industry is a little bit shielded from this but soon it will be the same when we see the speed AI is advancing.
No more joy crafting things as a dev…!
