We are surrounded by technology of a kind that our great-grandparents could barely have conceived of. And now it's threatening to change all our lives in ways we still don't understand.
So much of the technology we take for granted today - the technology that has revolutionized every field of human endeavor - emerged from Bell Laboratories (later known as Lucent Technologies) in the quarter-century following World War II. Bell Labs was a division of AT&T, on whose Board of Directors the estimable Vannevar Bush sat, starting in 1947.
Many have claimed that our present technology arose from contact with alien intelligences. Whether you believe that or not, one thing is certain: the rate of technological progress shot up like a rocket shortly after the end of World War II.
