And yet all the people who created all the advances in AI have extremely traditional, extremely good, fancy educations, and did absolutely bonkers amount of homework. The thing you are talking about is very aspirational.
There's some sad irony to that, making homework easier for future generations but those generations being worse off as a result on average. The lack of AI assistance was a forcing function to greater depth.
Outliers will still work hard and become even more valuable, AI won't affect them negatively.
I feel non outliers will be affected negatively on average in ability to learn/think.
With no confirming data, I feel those who got that fancy education would do so in any other institution. Just those fancy institutions draw in and filter for intelligent types, not teach them to be intelligent as it's practically a pre-requisite.
