Experience is just data. So one day when you go to Everest hiring a sherpa might not be needed. Why? Because a simulator can be created, based on his knowledge and all the other knowledge about Everest.

Regarding your other questions: Humans will build the machines that build the machines. In fact they do it now. Then we will build machines that can build machines based only on a design. That's the future.

The thing with the machines is a little bit different, but essentially it is much better to work from an office 2-4 hours a day, controlling a mining machine compared to actually mining.

Once a person can read there is almost no need for anyone else to teach him anything. I never listened in class, didn't have a notebook and got A's when I wanted to. I was reading the books that we were supposed to, but I prefered to explore them my way and I usually read them before it was needed. I know other people like me. I also know that people are curious in general and like to explore if given the opportunity.

And here comes my last answer - these people will do that because they want to see the result. Because they will enjoy doing it. And when they no longer find it interesting they will move on to something else. Because not doing anything is depressing. Doing it against your will - even more.
