"Strongly-recursive self-improvement" is a figment of the imagination; among the logical errors involved is confusion between properties of a program and properties of the world.
As for the rest: do you believe humanity can survive permanently as we are now, confined to this planet? If you do, then I will point you to the geological evidence to the contrary. If not, then it follows that without more advanced technology, we are dead. Neither I nor anybody else can know what will be the proximate cause of death for the last individual, or in what century, but certain extinction is certain extinction nonetheless.
Let us briefly review the discussion up to now since many readers use the the comments page which does not provide much context. rwallace has been arguing that AI researchers are too concerned (or will become too concerned) about the existential risk from reimplementing EURISKO and things like that.
You have mentioned two or three times, rwallace, that without more advanced technology, humans will eventually go extinct. (I quote one of those 2 or 3 mentions below.) You mention that to create and to manage that future advanced technology, civilization w...
In the early 1980s Douglas Lenat wrote EURISKO, a program Eliezer called "[maybe] the most sophisticated self-improving AI ever built". The program reportedly had some high-profile successes in various domains, like becoming world champion at a certain wargame or designing good integrated circuits.
Despite requests Lenat never released the source code. You can download an introductory paper: "Why AM and EURISKO appear to work" [PDF]. Honestly, reading it leaves a programmer still mystified about the internal workings of the AI: for example, what does the main loop look like? Researchers supposedly answered such questions in a more detailed publication, "EURISKO: A program that learns new heuristics and domain concepts." Artificial Intelligence (21): pp. 61-98. I couldn't find that paper available for download anywhere, and being in Russia I found it quite tricky to get a paper version. Maybe you Americans will have better luck with your local library? And to the best of my knowledge no one ever succeeded in (or even seriously tried) confirming Lenat's EURISKO results.
Today in 2009 this state of affairs looks laughable. A 30-year-old pivotal breakthrough in a large and important field... that never even got reproduced. What if it was a gigantic case of Clever Hans? How do you know? You're supposed to be a scientist, little one.
So my proposal to the LessWrong community: let's reimplement EURISKO!
We have some competent programmers here, don't we? We have open source tools and languages that weren't around in 1980. We can build an open source implementation available for all to play. In my book this counts as solid progress in the AI field.
Hell, I'd do it on my own if I had the goddamn paper.
Update: RichardKennaway has put Lenat's detailed papers up online, see the comments.
