LOL!
On a China salary given all the life extension that's going on, if you start saving now you'll be able to buy your grandkids those new brains they've been wanting while they'll still relatively young.
Man, the future is so weird. I notice in those prediction pages they say a reasonable few things about military technology into the future, but they don't predict what kinds of wars will exist. Big or little? Territorial/political or resource-driven? They do say that robots will eventually be fielded in warzones, and whichever side (the US) builds them firstest and bestest will enjoy a renewed boost in world power status. On the question of world population they do mention the possibility of calamitous natural disaster, but, as far as I could see, nothing too much about human-caused sudden population declines.
Actually someone somewhere said that as human life extends, so eventually the suicide rate goes up.
