The Evolution of GUIs and Input Devices

Stephen Wolfram answers questions from his viewers about the history of science and technology as part of an unscripted livestream series, also available on YouTube here: https://wolfr.am/youtube-sw-qa

Questions include: Is there much history on scientists (well known or not) starting companies? - If Leibniz was around today, where do you think he would be working, what would he be doing if he was not in academia? - Any interesting suggestions for history to research? - What's the history of walking meetings? Were there notable practitioners before you? - Was the first GUI+mouse+keyboard predictable beforehand or was it a surprise at the time?
