Slightly off-topic but I glad that the article mentions "Mother of all demos" [1] I watched this for the first time last year and I was shocked - Douglas Engelbart demonstrated what happens after 50 years. The mouse is the least amazing one but the demo featured real-time video conferencing and Google Docs-like real-time word editor with shared mouse pointers. It is hard to believe it's 1968 and he actually implemented them 50 years ahead. [1] https://youtu.be/yJDv-zdhzMY https://youtu.be/yJDv-zdhzMY
