From the very beginning of the talk:
I don't have to persuade you that, for instance, life is better than death; and I don't have to explain exactly why knowledge is a good thing, and that the alleviation of suffering is good, and communication, and travel, and space exploration, and ever-faster computers, and excellence in art and design, all good.
One of these things is not like the others.
Ever-faster computers jumped out at me when I first heard that sentence.
