Just some history ....Around 1982-83, a friend (future Microsoft coder) and me created a stock market game (semi-random number generator) using Basic and his family’s new IBM PC. We printed up and sold stock certificates to friends. He and I co-founded the Computer Science club at Santa Teresa High in 1987. I learned Pascal, apl, and HTML. APL when I worked in IBM at the Almaden Research Facility and Cottle Road campuses in HDA R&D circa 1989 to 1992. The internal IBM network was all terminal based, no WYSIWYG. Debugging was horrific. But we were used to using typewriters for long essays too. The first coding assistant I used was an HTML editor called HoT MetaL sometime in 1995. I worked just off Sandhill Road during the .com boom 1998-2000, though I was in medicine. And growing up and raising my kids in Silicon Valley means all my friends are/were semiconductor execs and successful founders. But I went on to other things, did not stay current, and haven’t coded in 3 decades. I also never took an accounting class, so none of this really means anything. Being a good investor in an industry does not require having worked in the industry. It just requires work.
