I can already imagine the lesswronger response: Something something bad comparison between neural nets and biological neurons, something something bad comparison with how the brain processes pain that fails at neuroscience, something something more rhetorical patter, in conclusion: but achkshually what if the neural network does feel pain.
They know just enough neuroscience to use it for bad comparisons and hyping up their ML approaches but not enough to actually draw any legitimate conclusions.
As to cryonics… for both LLM doomers and accelerationists, they have no need for a frozen purgatory when the techno-rapture is just a few years around the corner.
As for the rest of the shiny futuristic dreams, they have give way to ugly practical realities:
no magic nootropics, just Scott telling people to take adderal and other rationalists telling people to micro dose on LSD
no low hanging fruit in terms of gene editing (as epistaxis pointed out over on reddit) so they’re left with eugenics and GeneSmith’s insanity
no drexler nanotech so they are left hoping (or fearing) the god-AI can figure it (which is also a problem for ever reviving cryonically frozen people)
no exocortex, just over priced google glasses and a hallucinating LLM “assistant”
no neural jacks (or neural lace or whatever the cyberpunk term for them is), just Elon murdering a bunch of lab animals and trying out (temporary) hope on paralyzed people
The future is here, and it’s subpar compared to the early 2000s fantasies. But hey, you can rip off Ghibli’s style for your shitty fanfic projects, so there are a few upsides.
