Newt Gingrich said last night that the world will change more in the next 25yrs than it did in the last 100. We are just 100yrs from the Wright Brothers first flight, the mass production of automobiles, radio, tv, mirco electronics. But the next 25yrs will change more. He said there's more scientist alive today than at anytime in human history and they are all connected via the internet and instant communications. For better or worse the world will change, I believe biotechnology will spur huge advances in customized treatments for just about every disease known to man. Plus nanotechnology that will enable mico divices for the treatment of diseases.
