Oh, and the extreme brain drain the west imposed on everyone else, from South Africa to China, resulting in no available "brains", let's say, in those countries, and in the rich countries only brains available that aren't invested in making westerners smart, along with a disdain among existing populations of professions that require brains.
This is a huge assumption and not one I’m sure holds up. In my experience gaining competence is often more a matter of hands on experimentation and experience, and the thousands of pages of reference material are there to get you to the point where you can start getting hands on experience, and debug your experiments when they don’t work. If AI can meaningfully cut back on that by more efficiently getting people to the experimentation stage, it absolutely will be more effective. And so far in my limited experience, it seems extremely promising.
