| Interestingly, living forever is not a common desire among humans. As we age, our desire for longevity generally diminishes. Having children also seems to satiate some kind of internal biological self-preservation instinct, reducing the fear of death. (Which makes biological sense.) The simple fact is that we only fear death because our genes want to survive. Once that is accomplished -- or once we pass the age of reproduction -- the alien goddess of biology stops whispering that terror into our hindbrains. Myths of hells and grave-monsters and rotting corpses cease to haunt us so deeply. The desire to just be here becomes less intense. I would like to extend my life, but not because I fear death. I have children. It doesn't scare me all that much, really, though I would of course be afraid if it were staring me in the face. But I'd like to extend my life so that I could experience a kind of extended late-life in order to pursue intellectual ventures of high value and long-term focus. I'd love it if after kids, after ordinary biological life, I could basically become a monk-academic-entrepreneur and dedicate a century or two to art, science, philosophy, etc. Edit: In addition, through Gates' philanthropy, his selfish genes are in fact increasing their fitness. All those people in Africa are walking around with 99.999999% the same genetic material that's inside Bill Gates. He is them from a genetic point of view. So his actions are "genetically rational" from a perspective of selfish-gene self-preservation. Lots of human behavior makes more sense through this lens. Why, for example, do we exercise moderation in war? Because the enemy carries our genes. The whole point of war is probably evolutionary stimulation from a perspective of selfish-gene logic. My guess is that if we went to war against hostile aliens there would be absolutely no mercy or moderation. It would be all-out war, no holds barred. I do not disagree with the parent poster though. Such investments would have follow-on benefits and the technology would trickle down to us eventually, so I wish there was more money being put into those areas. |
