Whenever I see these fear of the future pieces, I'm always amazed at the author's in ability to think about the future in any kind of practical terms. Like, if we no longer died of old age, it wouldn't just be some switch that got flipped in everyone. It would be a long, drawn out, cost prohibitive change that would take years if not generations to trickle out. In that time, legislation would certainly be passed to deal with major issues, but minor issues would be addressed by shifting cultural norms or individual psychological changes. It's like the people who write these things claim to be imagining a world that's completely different, but it's really exactly the same except this one thing that would change everything. On another note, I really hope Zuck doesn't run for office. The idea of the head (or former head) of facebook being any kind of public official just raises all kinds of privacy flags for me.
