The curve could definitely be S shaped, but it's hard to say.
I think that I would be really unhappy/bored in a world where I got to experience "everything" I wanted to do. In fact, just the idea of not having to make any trade offs/compromises is incredibly paralyzing to think about right now lol
If the clones don't allow me to live forever, eventually dying would be the most interesting thing for me to do because it would be the only "new" thing left to experience in my lifetime.
