September 11 and the Rise of Robots : Discovery News

September 11 had quite a different meaning for me before it became 9/11. And early on that cool blue morning I took my daily run from our Chelsea apartment down the West Side Highway past the World Trade Center to South Ferry and back. I never thought much about the Twin Towers then, except sometimes to remember the convoluted history of how they got built in the first place, or to feel their overwhelming presence in what was then a low-rise part of Manhattan as I breezed past, with no sense of how gigantic their absence might become. At work later that morning, when the news came in, we first thought "accident." After all, in 1945 a B-25 bomber had crashed into the 79th floor of New York City's Empire State Building.
