Also, the difference between 200 years and 2^200 years enormous.
Yet when cast to a boolean is 'true' and when negated to equality instead of difference is 'false'. I suppose that kind of difference matters to people who, say, really don't want to ever die. The difference takes on a whole new meaning when it is the difference between (infinity - 200) and (infinity - 2^200)
Especially if we have a super-intelligence that is trying to make sure that the universe doesn't end.
The space of credible cosmologies where the will of even a super-intelligence from within the system being able to have an impact on that one way or the other seems comparatively small, does it not?
I haven't read a whole bunch on cosmology, but I don't think that that is entirely certain.
This seems to be your main objection and I think you're spot on.
I was immensely glad to find this community, because while I knew intellectually that I was not the only person who felt that rationality was important, death was bad, and technology was our savior, I had never met anyone else who did. I thus determined my career without much input from anything except my own interests; which is not so bad, of course, but I have realized that I might benefit from advice from like-minded people.
Specifically, I would like to know what LessWrong thinks I should do in order to get into "immortality research." Edit: that means "what field should I go into if I want humanity to have extended lifespans as soon as possible?"
I feel immortality, or at least life-extension, is one of - if not the - most important thing(s) humanity can accomplish right now. I don't think I am suited to AI work, however. Another obvious option is an MD, but that's not in my temperament either. My major right now is biochemistry, in preparation for a doctorate in either biochemistry itself, or pharmacology.
I think there's a good chance that advances in this area could contribute to life extension; aging is a biochemical process, right? And certainly drugs will be involved in life extension. But is this the best place to apply my efforts? I have considered that biogerontology (http://en.wikipedia.org/wiki/Gerontology) might be better, as it is about aging specifically; but I don't know much about the field - only that Wikipedia says it is new and very few universities offer degrees in it. My final idea is nanotechnology of some kind; I believe nanomachines may be able to repair our bodies. I'm not sure what type of nanotechnology I'd be looking at for this, or if degrees in it are offered.
Any ideas, suggestions, or comments in general are welcome. I favor the biochemical approach as of now, but only through temperament. As far as I know, AI, biochemical/pharmacological methods, and nanotechnology are all about equally close to giving us immortality. If someone feels one option is better than the others, or has recommended reading on the subject, please share!
Thanks in advance, my new rational friends.
