Please do Cryonics. If you're skeptical read this: http://waitbutwhy.com/2016/03/cryonics.html

Cryostasis still seems to be a thing:https://www.cryonics.org/ci-landing/human-cryostasis/

I'm a keen transhumanist, so yes I am familiar with the state of cryonics. I'm not a cryogenicist and couldn't put an actual number on the probability of success (neither could anyone else) but I'm aware of the serious challenges that face cryonics. For example, while the current chemical cocktail they're using as antifreeze is much more effective than the original solutions, the problem of cell deterioration due to cell membrane rupture still prevents the brain from bei

There's a genuine plausibility difference between inventing new surgical techniques and freezing corpses in liquid nitrogen hoping that future generations will resurrect them. In terms of the high certain burden on the rest of society (in terms of expending resources, denying others the use of one's organs, denying the use of one's remains for medical research or education, etc.) and the very outside chance that one will be successfully and happily resurrected (which is itself the product of sev

Cryonics may turn out to be easier :)

Cryonics could be made pretty cheap if lots more people signed up. It's only expensive because it's an extremely niche market. It's really a tragedy that cryonics isn't the default option. Even if you think it's unlikely to work, even a small chance at saving so many lives is worth it.Cryonics almost certainly works. They use chemicals which prevent the formation of ice crystals. Which is like 90% of the reason most animals can't survive being frozen. They'v

Invest in cryonics and be able to wake up in time.

You can sign up for cryogenic conservation of your body in case your near death so that you can be woken up when scientists find a way to revive you.

There absolutely no hope right now. The idea (for better or worse) is that there will be some scientific breakthrough in the future (e.g., nano-scale medical robots) that will make it possible to repair the damage done by the current, very crude, freezing technology. You're taking a gamble on future technology. My impression is that the typical person signing up for cryonics thinks that there's a small chance of success, but almost no downside if it fails (you're already de

Why crazy? There's good supporting evidence for sufficient preservation of fine neural structure via vitrification. The oldest existing cryopreservation organizations have lasted 40 years since their formation as professional groups. There is no known obstacle in the laws of physics to developing molecular nanotechnology capable of restoring a cryopreserved individual: it's just a technology challenge in organization at the nanoscale, related to well-funded and widespread current work
