There's an urban legend that I once got into a fistfight with Marvin Minsky, which does about as well as anything to illustrate the crazy, crazy things that people have been known to believe about me.
We have temporarily misplaced a great mind. See you later, Professor Minsky.
This kind of statement gives me great hope, and in particular represents the kind of fundamental mindset change that helps counter many of the painful aphorisms commonly pulled out when someone dies. I find it deeply unfortunate how rarely it applies, but as mentioned elsewhere in the thread, it applies here. Thank you.
But, as someone who plans on being cryo-preserved eventually, I'd say that whatever chance there is of reviving whatever remains of this individual, it should be taken. I'd want to live in the future, even if that meant not having my full cognitive abilities. Maybe not as very cognitively-impaired individual, but I guess I'll put that type of stipulation in the contract if I was worried about it.
