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?

It reminds me of this, which talks about this exact scenario:

Tldr is that for some very limited tasks it might still be preferable to use a human mind, especially if you can run it at 1000x cognitive speed. Or.....it might not. It's sci-fi at this point.

		It shouldn't remind you of that, my point is there's little economic use for uploads like this: if thinking meat is cheaper than thinking silicon, train some fresh thinking meat with an electrode array or whatever; if thinking silicon is cheaper, train some fresh thinking silicon. Non-economic use, that's different of course. Digital afterlife and so on, but as a consumer, not a supplier of anything.
