Yeah, that definitely won't work at scale. The bar for what constitutes being "educated" keeps increasing. Previously it was knowing how to code, now it is having an ML PhD, for example. At the same time, AI keeps getting more and more capable, so no matter how much "education" you have, AI will eventually get to you.

In any case, the argument won't work for majority of the population without a college degree. Are you going to have 50+ year old truck drivers upskilling in a fancy new tool to keep a job? And again, how long until that new skill you upgraded them to is now done by AI as well.
