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.
I'm not talking about old age, I'm talking about death. This includes death from plague, asteroid, LHC mishap, or paperclip maximizer. I didn't say "cure death" or "cure old age" but "[solve] the problem of death". And for the record, to my mind, the likeliest solution involves AGI, developed extremely carefully - but as quickly as possible under that condition.
Having refreshed, I see you've changed the course of your reply to some degree. I'd like to respond further but I don't have time to think it through right now. I will just add that while I don't assign intrinsic value to individuals not yet born, I do intrinsically value the human species as a present and future entity - but not as much as I value individuals currently alive. That said, I need to spend some time thinking about this before I add to my answer. I may have been too hasty and accidentally weakened the implication of "extinction" through a poor turn of phrase.
Note that this is dynamically inconsistent: given the opportunity, this value implies that at time T, you would want to bind yourself so that at all times greater than T, you would still only intrinsically care about people who were alive at time T. (Unless you have 'overriding' values of not modifying yourself, or of your intrinsic valuations changing in certain ways, etc., but that sounds awfully messy and possibly unstable.)
