I love this guy! He knows what he is talking about and presents his idea with sarcasm and humor. But I love his presentation at Ted for some other reason. Long time back when I was in High School, I had written a paper on future of human evolution, with naive mind set. I was wondering as to what humans would evolve into in the future. The evolution of humans from Apes took about 1.9 million yrs [SD .3 m yrs], which on Earthly time scale is very small. So where to from here?? Juan Enriquez has done a good job in showing a possible direction.
