Not an hour ago, my wife, who uses GPT all day, both at her job and as as her auxiliary brain even when she's not working, was telling me about her colleague discovering it. She's been using it since it came out, but doesn't make a show of it, so she was quite tickled the hear him going on and on about how amazing it is, how he just did two days of work in an hour using it, etc. But as a person who has been using computers for forty years, I'm actually rather surprised at how quickly people are picking up on it. When computers first got popular, I knew a ton of very smart people in the arts, writers, etc., who were extremely slow to come around to typing on the computer. I was at a research lab in the late 80's and I'd come home and tell people about using the Internet to email back and forth with people across the country, text conversations in real time, logging in on machines across the continent, etc., and get blank looks in return. Even very intelligent people didn't get it at all. A couple of years later, the WWW came out (1991, I think) and people started to understand, but it was very unnatural for most people.
