[Cooper watches you walk away] "Joe's path is a strange and difficult one..." - and I agree 1000% with your thoughts here.
I think part of this is about accepting the finiteness of the self. I am almost certainly well more than halfway through my time on this planet. There are a lot of things I wished I could have done, things I could have learned. And I will manage to do some of them, hopefully the ones that I feel would most fulfill and enrich me as a human being. But the stuff I don't get around to, I can't get too sad about. That's a nearly infinite reservoir of possible regret, and unlike so many of the regrets fate saddles us with, these you can usually simply opt out of.
And it's certainly not worth pretending that I did actually get around to those things, when I didn't. That would be like lying that I speak a language or play some instrument that I can't really... to, what? Impress someone at a party? I want them to be impressed with (well, I'd settle for just "like" / "tolerate") the person I actually am, not some fabrication.
So I think AI generators are mostly things that help you pretend, pretty unconvincingly, that you are infinite, did everything, knew everything. But the beauty of a life is in its finiteness, its specificities, its utterly unique rainbow scribble across time and space.
