From semiconductors to the internet, thanks folks. I have many mentors from this generation and I find a common thread of extreme discipline and rigor in their work - this is largely lost in my own generation (millenial).
Transfer of knowledge needs to be from prev to next gen. Unlike tutorials on YT teaching horrible practices, which is exactly the opposite. Experienced people from Gen X doesn't have the time, motivation, etc to go on YT with full blast click bait tutorials and compete with user engagement tactics. They write books. They're better than edu-entertainment IMO.
