Everyone was excited that Walter Cronkite was giving our high school commencement speech. He talked to us about robots. The entire class’s eyes glazed over. He told us that by the time our children graduated from college, the world would be run by robots. We wanted him to tell us that the world was our oyster, that we had infinite possibilities. And he was talking to us about robots. The girls in the class wanted him to talk about equality, how we could break the glass ceiling, and that there was a place for us in the work force. And he was talking to us about robots.
