There are lots of ways to live a great life and relatively few of them involve fame and fortune.
Also there are many people who make a big difference without achieving fame and fortune. Even within the tech industry I would argue that, for example, Dennis Ritchie's contributions were far more fundamentally important than any of the people you listed, yet he never achieved the massive wealth or mainstream fame of those you've mentioned.
I didn't say that you had to achieve massive wealth or fame. I said being that "idolizing someone for writing great code" isn't a worthwhile goal. Dennis Ritchie created two important products that are still used today: C and Unix. I think you'd find plenty of people would have a lot of bad things to say about C, for example, but it did solve a problem and help move the world forward.
By the way, why wouldn't you mention Bertrand Meyer or Niklaus Wirth?
