You can take ten seconds to see a long list of objections by googling “Cryonics is a scam”. You can go to Alcor and read a paper where a true believer suggests that the odds of revival are, at best, 15%, and that’s assuming magical nanomachines have a 99% chance of existing.
I’ll note here that the average estimated chance among regulars here for cryonics working is actually lower than that, and the difference in how seriously people on Less Wrong tend to take cryonics compared to the general population is less to do with thinking it’s much more likely than most people, and more to do with thinking that a chance of revival on that order is worth taking seriously.
