That was before the year 2000. Ever since, you will no longer get above the $100B unless you are a programmer. Non-programmers no longer stand a chance. You need to eat, sleep, and breathe technology these days. We will soon see the very last non-technology billionaire. Of course, it is a matter of principle for programmers not to turn any non-programmer into a billionaire by doing all the hard work for him. Let him do it instead!
