I remember seeing a TV show in the late 1960s, The 21st Century, where Walter Cronkite forecast or speculated about the future. I distinctly recall one episode where Mr. Cronkite predicted that the kitchen of the future would have a machine not to wash dishes, but melt them down and re-mold them into whatever you needed (bowls instead of plates, say). I recall in that same episode that he predicted that in the future, computers would be miniaturized to the point that it could sit on a desk, and this would revolutionize education. I was delighted this evening to happen across video clips from must have been that exact episode, which aired on March 12, 1967. One of them has Mr. Cronkite in the kitchen of the future; the other has him in the home office of the future. The latter is particularly amazing--the mockups are surprisingly similar to modern equipment, and the substance of the predictions, including information servers and video chat, are spot-on, as is the prediction that this equipment would be in everyone's home office.
