Mark Rosenfelder (aka zompist, of language construction kit fame) writes about the advantages and drawbacks of mortality and its alternatives, in fiction and real life. Rosenfelder, as an author, clearly takes Fun Theory very seriously. After discussing the mental and physical decline that age usually entail, he assumes that the most difficult to surmount of these problems will be the loss of mental flexibility and tolerance of novelty. He then uses this obstacle to offer interesting fun-theoretic arguments against uploading and cryonics:
One futuristic approach to the problem: get yourself uploaded to a computer, so you can stay alive indefinitely. I think it’d be horrible to give up food, sex, exercise, and the rest of our bodily experience, even if we posit that you can still somehow retain your visual qualia. But I can see the attraction of wanting to find out what’s next. Perhaps you could hibernate for fifty years at a time, then wake up and avidly consume all the pop culture that’s been created since last time. Avoid Sturgeon’s Law and read just the best 10% of stuff, forever!
However, I suspect the plan would fall apart in under 200 years. How much really grabs us from that long ago? We do read stuff that old, of course, but it’s only a tiny fraction of our mental diet. The past is a strange world that takes some effort to immerse ourselves in– when it doesn’t repel us with a mindset that’s now confusing, boring, or vile. 400 years ago is even harder to grok, and 1000 is an alien world. And looking back, I’d maintain, is far easier than looking forward. We’re exposed to the past as history and literature– we can read Jane Austen or Jonathan Swift or Molière far easier than they’d be able to understand us.
Imagine Jules Verne, for instance, trying to make sense of a Laundry novel. The prose itself might not be too difficult. The idea of monsters and government bureaucracies would be understood. But he’d miss the allusions to Lovecraft and spy novels, and references to the Cold War and computers would require a whole education to follow. Something like an episode of The Simpsons would probably produce complete befuddlement.
I’m not saying it couldn’t be done, just that it’d require quite a bit more work than it sounds like. And just visiting the future in one-year reading binges, you’d never really fit into the culture– you’d be an increasingly alienated dinosaur.
And how he addressed the issue in his own far-future conworld:
In the Incatena, I posit that the problem is solved by people loosening up their brains once a century or two. Basically, you lose a bunch of memories, fade out some of the more habitual neural pathways, recover some of the intellectual flexibility (and ignorance) of adolescence. Maybe change your body type and/or sex while you’re at it. You want to be you just enough to feel continuity, but not enough to become a curmudgeon. (And becoming an AI, though it’s an option, is viewed as a form of death.)
