But time is running out! Unless we find a way to effectively create energy, or we find a way to upload onto a reversible computing substrate, or Dust Theory is real, or we learn how to do alpha-point/line computing, or something else that fixes the problem, our light cone of the universe is not going to be habitable for that much longer and every planck time step counts. While I can't speak for anyone else who wants to live well past 100 years, indeed well past a billion if physics permits it, at least for me it's quite the disturbing conclusion to believe "time isn't running out, just be happy and focus on the present mon!" I reject the notion that "being happy" is a binary thing or some plateau of state of mind one achieves for some duration, though I think the concept of happiness as a fuzzy cluster of feelings that make one say "I feel happy" is a useful simplification. There are many forms of happiness of many durations, some quite complex and dependent on many variables or past states of mind. The chemical soup in a happy brain has many possible configurations. Even when I feel super-happy I still wonder if perhaps there's a higher form of happiness I could achieve, and then I wonder what sorts of happiness I'd experience with a different mind design (which is why I won't wirehead indefinitely even though wireheading would give all possible forms of human happiness). To me this post really comes across not as championing "happiness is what matters", but rather the more depressing "be content with your lot in life." No sah! That's for religious folk and for people who just crossed Atheist River but haven't finished questioning all their religious indoctrination! A better message I think is simply "If you aren't feeling the way you want to feel, change something. You don't have to feel that way you know, even if changing is really hard and takes years." But that's not really profound...
