Watch 25 minutes of Nicholas Negroponte's 2 hour talk from the very first TED conference in 1984. The full talk will be made available, but needs to be restored.
This is absolutely fascinating, especially if you can remember back to 1984 and the sorts of technology that were available. I had an Apple II at the time and considered myself very sophisticated. We had no idea that this work existed or had even been thought of (outside of Science Fiction novels).
