Anyone here considered cryo? the only thing putting me off is being trapped in an infinite torture with some bitter robot overlord. The good thing about death is just that. No one can suffer infinitely. We get to die. I read a short story once where this kind of happens. It's the end of time and 3 people are stuck in an evil machine who keeps them alive. Then one guy kills/free's 2 of the others. Can't remember what…

Imagine donating your body to science and then waking up in a lab as a brain in a vat. "A Living Soul" by P. C. Jersild is amazing sci-fi book exploring this. https://www.amazon.com/Living-Norvik-Press-English-Swedish/d... https://en.wikipedia.org/wiki/P._C._Jersild

I can't wrap my head around what it would be like to exist merely as a consciousness within my brain, lacking any sensory organs to perceive the surrounding world. Of course, I've also never been in a sensory deprivation tank.

My naive guess is that, although very jarring at first, most people would actually get used to it in not too long of a time. Humans adapt easily. Also, if they can achieve that feat, they could probably also trick the brain into feeling like it has robotic or virtual body parts.

Maybe people with locked-in syndrome could provide some reports of what it's like. It's not the exact same, but it may be similar.

Earlier quoted context omitted.

All response experience exists within the brain, yes, but it is only ever made possible through external stimulus. The brain itself doesn't feel anything, but generates those feelings as a response to events outside of itself. "If it seems strange that nerve signals coming from the back can represent vision, bear in mind that your own sense of vision is carried by nothing but millions of nerve signals that just happe…

Your brain can't hurt, but presumably a phantom body could be made to hurt by providing the right neural stimulation.

It'd actually be fantastic. If I've donated my brain to anything like the modern research apparatus, I can be relatively sure of one of two possibilities: Either my brain was chosen as a test, in which case the project is on the news literally worldwide and the ethics have had the crap argued out of them and I can be sure that any limitations of the environment are due to technological shortcomings and I get to participate in fixing it, or I'm part of a follow-up trial or large-scale roll-out, in which case they'll have fixed up the rest of the issues. In the first case I get to be a grad student again, albeit with a bit of a disability. In the second case, I'm catching a rez from a reasonably reliable medical procedure and the major issues have already been worked out. In both cases I'm no longer dead, and these scenarios are nowhere near having enough downsides to outweigh that.

> Throwing it out there—when I'm dead, you are totally allowed to resuscitate my brain. Better than being dead. Are you comfortable with the possibility that those who are reviving you might not be doing it for your benefit?

I think so. Still better than being dead. (If they're explicitly trying to cause me pain, that would be a no.)

There won't be any pain as brains don't have nerve endings. But you won't have any other senses too. Just pitch blank, deathly silence, floating for eternity.

Nerve endings receive pain. The brain "feels it".

So it can easily be made to feel pain -- just pass in the same signals the nerves would have.

Sounds like a Lovecraft horror piece which is actually something of a trope at this point:

Throwing it out there—when I'm dead, you are totally allowed to resuscitate my brain. Better than being dead. Please make sure I am supplied with some good books to read, if at all possible.

In Blindsight by Peter Watts, there are a group of revived soldiers that serve as mercenaries. Upon dying, they are 'resurrected' and immediately given a choice to go back to being dead -or- pay off the resurrection fee by serving as a zombie soldier for 8-10 years. If they survive their service, they are free to continue living in whatever mangled state their body currently is. They unaware/unconscious while serving, so they won't have any memory of the horrors that they commit or are acted upon them.

It would be strange to return to your life after dying 10 years ago, but I'd probably take the deal.

I don’t see why they bothered drugging the brains. Even if they became conscious, the pig’s bodies are dead and gone. There is nothing to feel, one is simply alone with their thoughts, perhaps even dreams.

Perhaps the fact the the brain was disconnected from the body was a major factor in why no signs of consciousness were recorded. Consciousness may be the byproduct of a living body sending signals to a living brain.

> Consciousness may be the byproduct of a living body sending signals to a living brain.

Might be, but unlikely. Both our medical and legal (executions) experience shows that most parts of the body can be removed or paralyzed without impacting consciousness. It really seems like the obvious model - that the brain alone is the center of consciousness - is the correct one.

I have no mouth and I must scream https://en.m.wikipedia.org/wiki/I_Have_No_Mouth,_and_I_Must_... Is it this?

wow. amazing. so much came back to me reading that. was a long time ago. thanks!. But ye, before this book I was well up for cryo. Since, I've decided death is probably for me.
