I think it ultimately just comes down to laziness. People are increasingly loathe to make multi-year plans and stick to them, for various reasons.

Building something like a YouTube competitor is theoretically doable by a small team. It’s vastly more possible with AI tools than it was a decade ago.

But the “muscle” of doing difficult things has atrophied for many people, in large part because the AI tools themselves reduce your ability to actually do the work. If day after day, you just prompt an AI to make things for you, do research for you, etc. then you gradually stop working that muscle yourself.

It makes me think that the ideal usage of AI tools might be a deliberately limited one: do everything on your own, but check in with the AI once a week for review.
