This whole AI is like humans thing is so exhausting. It's obviously not the same thing. A human can't ingest all of the library of Alexandria, and then generate dollars for their employer regurgitating those books.
I see AIs today who have done that. I am sympathetic to them because I wish I could have been them and achieved what they have. Don’t demean human learning just because we have systems that can learn like us.
You'd have to devour the library of congress, and every public scientific paper, and most of the text on the internet. Likely much more than you could read in a lifetime.
Then you'd have to be able to regenerate a realistic imitation of any book, on demand, in a minute, for a few cents.
