MIT researchers predict 'global economic collapse' by 2030

Ray Kurzweil:

"At what point do humans cease proliferating? How many humans can Earth reasonably accommodate?

We can actually accommodate a greatly expanded biological population. We have 10,000 times more sunlight than we need to meet 100 percent of our energy needs. The total amount of solar energy produced each year is doubling every two years and has been for thirty years and is only about seven doublings from meeting all of our energy needs. There is a similar analysis with water and food and production of housing. The vast majority of land is not used today for human habitation. But ultimately – about a century from now – we will be more concerned with resources for our non-biological brains and bodies than our biological ones."

Won't someone please think of the robot bodies!?!

This is based on a report from the 1970s, and it assumes continued population growth. We've been watching our population growth decline for years, and now we're seeing human energy usage begin to decline as well from economies of energy efficiency.
