as with every discipline that AI and therefore computers can reason through suddenly:

you could always do the discipline you liked before for self fulfillment purposes, and you can still do it for self fulfillment purposes now

But most people who want to get good at their main discipline, even for self-fulfillment purposes, have been gaining the necessary experience through their job, because an unrelated job takes away too much time to do so.

its a good motivator and looks like we'll be returning to the more feudal version where just that class was focusing on the arts, only because everyone else is preoccupied with doing the things that pays the bills

unless they're actually serfs again and won't have bills to pay, but no access to anything outside of the fiefdom that they maintain all day
