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.
That's the whole point though - I can't, and I don't think anyone can. Right now the LLMs are just getting bigger and bigger, we're bruteforcing the way out of their stupidity by giving them bigger and bigger datasets - unless something fundamental changes soon that tech has an actual dead end. Hence my (joke-ish) prediction that you'll eventually need a 16PB GPU to run a basic gemini model, and such a thing will always be very expensive no matter how much our tech advances(especially since we are already hitting some technical limits). Human brains won't get any more expensive with time - they already contain all the hardware they are ever going to get - but what might get cheaper is the plumbing to make them "run" and interact with other systems.
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?
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.
Non-economic use, that's different of course. Digital afterlife and so on, but as a consumer, not a supplier of anything.
As the technology improves, it will be mostly just for the rich and less for prisoners, and as costs fall further there will even be financial pressure for the rest of the population to "go digital": insurance on digitized lifeforms will be much cheaper, replacement robot body parts, replacement electronics, versus expensive healthcare.
Look up the fraction of GDP in developed nations that goes to healthcare and insurance. People will be shamed by the economy as if they are uppity for hanging on to their slow, expensive to feed and maintain meatbag bodies.
