Almost anyone learn anything they want now. This all cuts both ways.
If security is a solved problem then anyone that wants to teach themselves enough can move to trying to solve disease, until disease is solved, then we all move on to building enough robots to mass produce enough food to solve world hunger and shelter... and once the needs of everyone on earth are solved at an ever cheaper price until it is free... then I guess we do whatever we want.
Only way to earn a good living is to pivot to solving diseases for a few years until robots solve world hunger and shelter. Then we can do what we want without the money to do it?
