A downside that I haven't seen much attention paid to, although it does get mentioned from time to time, is the problem of having the organisation that has the care of your corpsicle surviving long enough, and taking good enough care. You can't freeze a social structure and put it in a vat for a century -- it has to live through all the time that you don't. What are the chances?
There's a flip side to that, which is that a cryonicist who takes the idea of reanimation seriously must also take the idea of future stability more seriously. Unlike any other living person they have reason to anticipate the long-term results of today's political stances, investments, and social developments in terms of actual sensory experiences. I'm not sure if this actually translates to increased rationality, but seems like should.
The Cambridge UK meet-up on Saturday 12 February went really well. Many thanks to everyone who came and provided a wonderful and entertaining discussion.
One of the topics that came up was that of cryonics. This is the idea of having your body (or maybe just your brain) frozen after death, to be thawed and revived in the far future when medical technology has advanced to the point where it can heal you. Is this a rational thing to do?
The argument I heard from some of the other attendants effectively boils down to “what have you got to lose?” In other words, have yourself frozen just in case it works and you can be resurrected.
This struck me as awfully reminiscent of Pascal’s Wager, which is similarly a “what have you got to lose?” type argument. Cited in its original form, it is about belief in a god and goes something like this:
This argument falls down on many counts, but I’ll concentrate on a specific one. It makes a far-fetched assumption about the set of possible outcomes. It assumes that there are only the two possibilities quoted and no others. It ignores the possibility of a god that only rewards sceptical atheists.
Coming back to cryonics, the argument seems to proceed approximately like this:
If I haven’t already made it abundantly clear, the assumption that the future you wake up in is at all desirable for you is a far-fetched one. It ignores the possibility of waking up as a slave with no opportunity for suicide.
What are everybody’s thoughts on this?
