I agree with you and disagree with the OP in similar ways.

I work on my own "agentically-engineered" projects and the pursuit of certain ideas for what you're calling intrinsic motivation, and I don't particularly care if others find it interesting or even find it at all or not, because the ideas themselves are cool to me.

It's kind of like I can suddenly tinker at 2,000% efficiency and share what I'm doing, _and if someone else finds it interesting, that's cool too_

Isn’t the point you’re making what OP is saying - that there are of course some humans who have deep intrinsic motivation, and they’ll continue to do what they do, but most humans aren’t wired this way, and for that, society will collapse?
