I'm afraid it was no mistake that I used the word "faith"!
This belief does not appear to conflict with the truth (or at least that's a separate debate) but it is also difficult to find truthful support for it. Sure, I can wave my hands about complexity and entropy and how information can't be destroyed but only created, but I'll totally admit that this does not logically translate into "life will be good in the future."
The best argument I can give goes as follows. For the sake of discussion, at least, let's assume MWI. Then there is some population of alternate futures. Now let's assume that the only stable equilibria are entirely valueless state ensembles such as the heat death of the universe. With me so far? OK, now here's the first big leap: let's say that our quantification of value, from state ensembles to the nonnegative reals, can be approximated by a continuous function. Therefore, by application of Conley's theorem, the value trajectories of alternate futures fall into one of two categories: those which asymptotically approach 0, and those which asymptotically approach infinity. The second big leap involves disregarding those alternate futures which approach zero. Not only will you and I die in those futures, but we won't even be remembered; none of our actions or words will be observed beyond a finite time horizon along those trajectories. So I conclude that I should behave as if the only trajectories are those which asymptotically approach infinity.
Is this a variant of quantum suicide, with "suicide" part replaced by "dead and forgotten in long run, whatever the cause"?
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.
