>> We're actually on a trajectory for human brains becoming the most expensive option for basically any job.
Unless RTX9000 with 16PB of ram needed to run basic Gemini2077 model costs more than a house, but a brain jar with electrodes is cheaper than that. Then the economic incentives will shift the other way.
We can already grow brain organoids cheaply and easily enough to be a YouTuber's long-running series, so even if biological somehow gets cheaper than silicon, it still isn't going to be a revived complete human brain from someone who died 50 years earlier and probably retired 20 years before that.
I mean, imagine someone who got themselves cryonically preserved in 1976 getting either revived or uploaded today: what job would they be able to get? Almost no office job is the same now as then; manufacturing involves very different tools and a lot of CNC and robotic arms; agriculture is only getting more automated and we've had cow-milking robots for 20-30 years; cars may have changed the least in usage if not safety, performance, and power source; I suppose that leaves gardening… well, except for robot lawnmowers, anyone who can hire a gardener can probably afford a robo-mower?
No I don't think so. We can already create LLMs that are highly efficient and infinitely more knowledgeable than any single human being, completely tuned to the task, without ego or distractions, and they are cheap enough that you can run tens of them in parallel for a few hundred dollars per month. They are also way faster than any human being. And we're three/ four years in this. Imagine 50 years from now.
