I've long been fascinated by the evolution of Bill Gates. I cut my teeth in this field as an engineer at Netscape, where I watched along with the rest of the industry as Microsoft did what they did to Netscape and all of the following legal proceedings and DoJ activities ensued. While I still respected the story and beginning of Gates (reading everything I could about him, when I was a teenager), I hated Mr. Borg with a passion and everything about Microsoft. It was what drove me to the arms of Linux and, ultimately, Unix (and my career therein).
Then, he decided to move on from just leading a tech and business army and raking in cash to making finding a way to properly use that cash for the betterment of man. We saw a completely different side of him. Perhaps a new side of the guy that game with maturity and wisdom. I gained a completely new respect for him. I still disagree with some of his views, completely disagree with some of his former business practices, am frustrated and dismayed with a lot of Microsoft's current endeavors and decisions . . . but as a man -- I've come to have a lot of admiration for what he's doing. He's a great example for the rest of the world's wealthiest in doing something truly constructive and beneficial with their unimaginable wealth.
Americans love a success story and we love a story of personal redemption. The only thing we love more than hating someone is them turning things around and giving us reasons to be in their corner. This is one of those stories. And, personally, I find his activities a solid reminder in my own personal life to remember how fortunate I am in my career. As a direct result, I make a point of doing what I can to support things like Engineers Without Borders. I bet many other engineers out there have found the same respect and inspiration.
I also find it sad that, for as inspiring as I found Jobs as far as business and design, there is simply no similar compelling feeling in that same way, after his passing.
