Scientists can now keep brains alive without a body

Sometimes even consent doesn't work very well. Roald Dahl described just this situation (for a human) back in 1959 in this story: https://en.wikipedia.org/wiki/William_and_Mary_(short_story)

Perhaps they would need to send false sensory stimuli to emulate a ghost-like body illusion and maintain the isolated brain in an induced state of normalcy.

Or better yet, an underground vault, connected to the Internet. Our brain is our most valuable possession; it seems silly to carry it around with us if we didn't need to.

If this were Reddit that'd earn gold. Brilliant idea. I mean the brain is what we are essentially... If we just ditched the bodies and stored our brains forever, my mind is blown by this. This would be a great company to start, would probably get tons of funding by sv too. We could still experience life especially if we can create bodies that feel like human ones. Even immortals could get hot by a bus, but not if the brain is miles away in a nuclear bunker...

I think we’d soon find out that a brain without a body operates very differently than when the brain is in the body. The brain relies on the body’s sensory organs for much of its decisions, how can it compute things when these are removed?

And also - if we managed to extract data from a brain, could we hold someone guilty for what we pull out? Would the brain say different things than the mouth? Which one is correct?

I don't really see what impact this has on our ability to extract information from a person's brain. We can already stick brain-computer interfaces into a brain while it's attached to the rest of a body. The significance of this technology combined with BCIs is in my opinion positive; that people may be able to have a meaningful conscious existence without a body, beyond their natural death.
