I think that on this subject, I am most at odds with my Silicon Valley friends. Most people I talk to seem to want to live forever if possible.<p>I think this would be a disaster. We would create a race of ultra wealthy Methuselahs who dominate the world and prevent the very "creative distruction" that Valley types claim to worship.<p>Talking about this subject is very like talking about vegetarianism. Many people would admit the basic premises under the practice, yet find some reason to ignore those premises and just keep doing what they're doing.<p>Are we doomed to destroy the world in our selfishness? Or is there a hidden upside to everyone (or worse, a select few) living forever on a finite planet?
