Re: Like those Chryogenic companies
Do we know that for sure? Is it possible that our personalities are coded into the connections in our brain, so that some future tech could sort of rebuild us from that info? Seems rather unlikely. Also, I'm not sure being frozen just as your hear is giving up the ghost is going to be all that much help either. Surely you need to be frozen with a couple of days left of life, so that future medical tech has a decent run at saving you.
Of course the this is all covered in Larry Niven's Known Space stories. He assumes rather more people froze themselves in the 20th Century than actually did. When the technology comes to revive them, the corpsicles as they're known, their bodies are still destroyed by formation of ice crystals. I can't now remember if it's brain transplant or some sort of hand-wavey personality transplant. But anyway they get revived, but into the bodies of executed criminals who've been mind-wiped and then enslaved until they've paid off the hideous cost of their medical bills. I didn't say it was a cheeful future, as it also involves forced organ harvesting for parking offenses...
