Sex. Touch. The novelty of knowing it's not AI. To feel the novelty of pain instead of pleasure, etc. Hedonic adaptation will eventually saturate and the only direction of novelty will be less not more. I see it like someone doing Cocaine or Heroin. Eventually you cannot take more. You just die/destruct.
Alan Watts hinted at the novelty portion of ^^:
So then, let’s suppose that you were able every night to dream any dream you wanted to dream, and that you could, for example, have the power within one night to dream 75 years of time, or any length of time you wanted to have.
And you would, naturally, as you began on this adventure of dreams, you would fulfill all your wishes. You would have every kind of pleasure you could conceive. And after several nights of 75 years of total pleasure each you would say “Well that was pretty great. But now let’s have a surprise, let’s have a dream which isn’t under control, where something is gonna happen to me that I don’t know what it's gonna be."
And you would dig that and would come out of that and you would say “Wow that was a close shave, wasn’t it?”. Then you would get more and more adventurous and you would make further- and further-out gambles what you would dream. And finally, you would dream where you are now. You would dream the dream of living the life that you are actually living today.
