To support the grand-post but reword it: we're on the verge of AI becoming a "great creativity equalizer". It used to be that each individual had a "skill level" on a scale from 0-100 for each practice, where very few people were above level 60. But now everyone can be a level 60+ artist, if they want to be. This lower limit will keep rising and, at a certain point (and maybe were talking 1000 years) it will be hard for anyone to differentiate any everyday media from human- vs AI-generated.

Maybe equality is good? For utilities like locomotion, that sounds great. But for creativity?

I think what will happen is a later generation will grow up bombarded by level-100 art and music. I guess that sounds net positive...right?

As a musician, I can tell you one thing: part of what gives me drive to make music is knowing that what I'm creating is a scarce resource. (For example, if I realize one of my songs sounds like another existing song, it stops sounding good to me.) If it comes that AI can generate new songs for me, all of that value I assign to creating music is lost.
