BTW, if you think Bill Gates is ruthless, what about Jack Tramiel?
I have no love for Jack Tramiel - or any other head of a large corporation. They're not the creators, they're the people who provide the financing based on potential profits. They get the credit for doing great things when really their motivation was just based on greed. The actual creators are usually forgotten. Does anybody remember the guy who wrote QDOS/86-DOS which was the basis of MS-DOS and lead to Windows? I don't - but Bill Gates gets credit.
