As promised, here is the "Q" part of the Less Wrong Video Q&A with Eliezer Yudkowsky.
The Rules
1) One question per comment (to allow voting to carry more information about people's preferences).
2) Try to be as clear and concise as possible. If your question can't be condensed to a few paragraphs, you should probably ask in a separate post. Make sure you have an actual question somewhere in there (you can bold it to make it easier to scan).
3) Eliezer hasn't been subpoenaed. He will simply ignore the questions he doesn't want to answer, even if they somehow received 3^^^3 votes.
4) If you reference certain things that are online in your question, provide a link.
5) This thread will be open to questions and votes for at least 7 days. After that, it is up to Eliezer to decide when the best time to film his answers will be. [Update: Today, November 18, marks the 7th day since this thread was posted. If you haven't already done so, now would be a good time to review the questions and vote for your favorites.]
Suggestions
Don't limit yourself to things that have been mentioned on OB/LW. I expect that this will be the majority of questions, but you shouldn't feel limited to these topics. I've always found that a wide variety of topics makes a Q&A more interesting. If you're uncertain, ask anyway and let the voting sort out the wheat from the chaff.
It's okay to attempt humor (but good luck, it's a tough crowd).
If a discussion breaks out about a question (f.ex. to ask for clarifications) and the original poster decides to modify the question, the top level comment should be updated with the modified question (make it easy to find your question, don't have the latest version buried in a long thread).
Update: Eliezer's video answers to 30 questions from this thread can be found here.
An over-generalisation of self-preservation instincts certainly seems to be part of it.
On the other hand, one of my interests is in the spread of ideas. Without cryonic medalions, cryonic bracelets, cryonic advertising and cryonic preachers there wouldn't be any cryonics movement. There seems to be a "show your friends how much you care - freeze them!" dynamic.
I have a similar theory about the pyramids. Not so much a real voyage to the afterlife, but a means of reinforcing the pecking order in everyone's minds.
I am contrasting this signaling perspective with Robin's views - in part because I am aware that he is sympathetic to signaling theories in other contexts.
I do think signaling is an important part of cryonics - but I was probably rash to attempt to quantify the effect. I don't pretend to have any good way of measuring its overall contribution relative to other factors.
