city of the future

Here I sit, on a fully-automated robot train, typing a message that I will trnasmit by radio to in-turn be relayed by wire and light to San Francisco where it will be automatically published. The message will be read on cathode ray tubes and liquid crystal displays across the continent from Vancouver to Los Angeles to Miami to New York. It will be read at opposite ends of the earth, from Europe to Australia. And this is all a routine part of my Monday morning commute.
