The greatest thing either of these men have done with their lives is commit to philanthropy. Everything else pales in comparison, and the biggest impact they will have on the world will have been through their philanthropy. They'll be remember for two things: being filthy rich, and what they did with those riches. Little will be remembered about either of the men personally, I dare say.

Tell me, downvoter, what Bill Gates and Warren Buffet have done that will be more memorable than perhaps in a few years having wiped out malaria? Windows Vista? The Zune? Buying Gillette and Geico?

Downvotes contribute nothing to a discussion, and without commentary they serve little purpose, save to inform the downvotee that you have something against what they said yet felt disinclined to share it..
