I read "How I Found Freedom in an Unfree World" by Harry Brown in 1973. He mentions at one point that he is not a radical as Ayn Rand, so I looked her up. Been hooked ever since. I spent most of 25 years in large scale engineering and construction, got an Apple II in 1980, and have been hooked on computers since then. Now doing cyber security and still reading Ayn Rand.
