Yeah, that’s pretty much what I was thinking of.

Let’s say your borrow a bunch of books from the local library and read them in order to refine your writing skills. Later, you’ll write a book that is more or less inspired by all of the books you’ve previously read. Do you owe something to the hundreds of authors you got inspired by? Even if you bought those books, do you think the other authors would could still demand something extra because clearly those books weren’t really used for mere entertainment. Instead, they were used to train a new writer.

If it hasn’t happened already, I’m pretty sure there’s going to be a lawsuit about this sort of thing. Then the judge would need to figure out if there’s a difference between a human reading a book for entertainment and training to become a writer.

There's only so many jobs that can be automated before there simply aren't enough jobs. We're about to reach that point.

Once you automate intelligent jobs, what jobs are left?

A better metaphor is the car putting horses out of a job. What happened to horses? They didn't all magically get new jobs to replace their old ones. What is stopping the same thing happening to humans? Except the people who owned the horses are instead the owner class that owns the robots/AIs.

Once many struggle with finding a job (not to mention.. many already are), what will happen on a societal level? Will we be willing to redistribute wealth to make sure everyone has a decent standard of living even if they can't find a job? We haven't been willing to do that so far.
