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.
Let E(t) be the set of historical information available up until some time t, where t is some date (e.g. 1934). Let p(A|E) be your estimate of the probability an optimally rational Bayesian agent would assign to the event "Self-improving artificial general intelligence is discovered before 2100" given a certain set of historical information.
Consider the function p(t)=p(A|E(t)). Presumably as t approaches 2009, p(t) approaches your own current estimate of p(A).
Describe the function p(t) since about 1900. What events - research discoveries, economic trends, technological developments, sci-fi novel publications, etc, caused the largest changes in p(t)? Is it strictly increasing, or does it fluctuate substantially? Did the publication of any impossibility proofs (e.g. No Free Lunch) cause strong decreases in p(t)? Can you point to any specific research results that increased p(t)? What about the "AI winter" and related setbacks?
I'd guess that WWII and particularly the Holocaust set it back rather a lot. How likely were they in 1934 though, possibly quite.
