Lawrence, Paul, I cheer to see this conversation joined. It's perhaps the most important of all. The boomers, like we subsequent generations, seem unfairly fated to die. But there's a solution for that, too.
Philip Rieff, whose tocsin I shall keep sounding, refers us to Donner Professor of Science at MIT, and founder of that school's Artificial Intelligence Laboratories, Marvin Minsky:
"Should we robotize ourselves and stop dying? I think the answer is clear for the long run because in a few billion years the sun will eventually burn out and everything we've done will go to waste. [...] Is it possible, with artificial intelligence, to conquer death? [...] Then eventually there'd be no room for more new people, and that would raise more problems."
Minsky gave us that little wonder of scientific fantasizing back in 1985, a year that science itself has since left deep in the dust. Fukuyama too predicted "our posthuman future," but science, like always, lends only a helping hand. Posthumanity is, in fact, just a culture away.
