Interesting how he was kind of, but not quite, on the right track in terms of predicting where technology would go. Small "wearable" (in the sense that you carry them on your person) computers obviously became huge, but not in the way that he was thinking. I was a kid back then, so wasn't thinking too deeply about the future of technology, but mobile phones were already a thing and some were becoming internet-compatible, so in hindsight smartphones seem a more obvious next step than "a special glove that can recognize a digital sign language". Maybe not at the time though.
