Sure but the ratio of required neurologist and psychologist for a certain population is rather low, lower then IT specialist. The majority of people are fine socializing, memorizing without fully understanding the underlying mechanics. Its only when a complex problem arises that we need them.

I find there is a different between unnecessary and not required. For the most part, running and maintaining the day to day operations and code, humans wont be required, but in order to progress human society as a whole (a goal wich is not required but we will set regardless) we will find it necessary to have expert human overheersers. Aided by ai themselves we will really only need a few smart and dedicated people to help make a few rare decisions. The massas are free to do, play, learn or be blissful as they like

Provided with enough freedom to dedicate yourself to any possible education there will always be people who will be interested enough to become these experts. With personalized Ai teaching aids more people will also be able to become high level experts quicker. If not only because I myself have greatly own expertise because i recognize gpt4 as the forever patient and personal teacher i never had.

With ai polling and transparancy in who the experts are we can guarantee democratic trust.
