I thought we were talking about creation of advances, not who is better at shady business practices. Dr. Kildall is the one who created the product. Bill Gates is the one who bought and marketed a ripoff of it. Why is the latter supposed to be viewed as the one who has advanced our technology and is so creative?
I also note that you neglected to mention a large trust fund of poor-little-rich-kid Bill Gates.
"Ask Bill why function code 6 (in DOS) ends with a dollar sign . . . . No one in the world knows that but me." --Gary Kildall, PhD
Who deserves the most credit for the automobile? The man who invented it -- Charles Duryea? Or the man who changed the way the world got around -- Henry Ford?
Don't dismiss what Gates did just because he didn't invent DOS.
