This post is shameless self-promotion, but I'm told that's probably okay in the Discussion section. For context, as some of you are aware, I'm aiming to model C. elegans based on systematic high-throughput experiments - that is, to upload a worm. I'm still working on course requirements and lab training at Harvard's Biophysics Ph.D. program, but this remains the plan for my thesis.
Last semester I gave this lecture to Marvin Minsky's AI class, because Marvin professes disdain for everything neuroscience, and I wanted to give his students—and him—a fair perspective of how basic neuroscience might be changing for the better, and seems a particularly exciting field to be in right about now. The lecture is about 22 minutes long, followed by over an hour of questions and answers, which cover a lot of the memespace that surrounds this concept. Afterward, several students reported to me that their understanding of neuroscience was transformed.
I only just now got to encoding and uploading this recording; I believe that many of the topics covered could be of interest to the LW community (especially those with a background in AI and an interest in brains), perhaps worthy of discussion, and I hope you agree.
There's the rub! I happen to value technological progress as an intrinsic good, so classifying a Singularity as "positive" or "negative" is not easy for me. (I reject the notion that one can factorize intelligence from goals, so that one could take a superintelligence and fuse it with a goal to optimize for paperclips. Perhaps one could give it a compulsion to optimize for paperclips, but I'd expect it to either put the compulsion on hold while it develops amazing fabrication, mining and space travel technologies, and never completely turn its available resources into paperclips since that would mean no chance of more paperclips in the future; or better yet, rapidly expunge the compulsion through self-modification.) Furthermore, I favor Kurzweil's smooth exponentials over "FOOM": although it may be even harder to believe that not only will there be superintelligences in the future, but that at no point between now and then will an objectively identifiable discontinuity happen, it seems more consistent with history. Although I expect present-human culture to be preserved, as a matter of historical interest if not status quo, I'm not partisan enough to prioritize human values over the Darwinian imperative. (The questions linked seem very human-centric, and turn on how far you are willing to go in defining "human," suggesting a disguised query. Most science is arguably already performed by machines.) In summary, I'm just not worried about AI risk.
The good news for AI worriers is that Eliezer has personally approved my project as "just cool science, at least for now" -- not likely to lead to runaway intelligence any time soon, no matter how reckless I may be. Given that and the fact that I've heard many (probably most) AI-risk arguments, and failed to become worried (quite probably because I hold the cause of technological progress very dear to my heart and am thus heavily biased - at least I admit it!), your time may be better spent trying to convince Ben Goertzel that there's a problem, since at least he's an immediate threat. ;)
Why would you believe that? Evolution was more than capable of building an intelligence that optimized for whatever goals it needed, notable reproduction and personal survival. Granted its version was imperfect, since humans have enough conflicting goals that we can sometimes make moves that are objectively bad for the perpetuation of our gametes, not to mention the obvious failure cases lik...
