David Brin has given this speech, or one like it, to a great many groups. He has finally written it up, cleaned it up, and published it. In it he posits that security v. freedom is a false dichotomy, and damn we've come a long way from feudalism, and more; all topics he covers in more detail in his book The Transparent Society. I must admit that I was a bit taken aback when I first read the book, because I had bought into most of the unspoken assumptions. I'm delighted, though, because I want to think that my daughters will have a better life than I have, in mostly the same way that my life is better than my parents', and theirs was better than my grandparents', etc ad infinitum.
