I'm starting to worry that we're going to run pretty short of activities humans find fulfilling to do, that have any notable amount of extrinsic reward or value.
What happens when the computer does tell better stories to your kids than you do? When you turn the computer loose on them for a week and, well, god damn, by the end of the week they seem to have taken exactly the lessons they needed and are bringing them up in real-life situations and are even getting better at reading themselves, and raving about how good the stories are, and you can't deny that if you'd done it, the results wouldn't have been as good?
Now repeat for all the ways that humans find it satisfying to serve others using their creativity.
I very much doubt it's healthy for all the things we find fulfilling and enjoyable to have only intrinsic motivation to drive them.
It's hard to turn down better outcomes, but what if a side-effect is that as a species we become psychologically (even spiritually, if you will) lost? So kids are raised more effectively—but for what? So that all the things they enjoy doing are valuable to, and needed or wanted by, exactly no-one?
So we get more efficient at producing goods and entertainment—for what? So the brushes and paints we buy for our paintings that nobody cares to see and that your talentless cousin can outdo—in every way, including sublimity and mood and all that—with a lazy prompt on some future image generator, are somewhat cheaper? What's the point?
