"We would like every country to be self-sufficient so that both in terms of running a good primary health care system and funding a good primary health care system, it's all OK, and they just participate in regional bodies that have standby capacity to deal with these things. Africa, of all the places in the world, is the furthest behind on being able to do that. And through aid, health and health systems in Africa have improved very, very dramatically."

“The harsh mathematics of polio makes it clear: We cannot maintain a level of one thousand or two thousand cases a year. Either we eradicate polio, or we return to the days of tens of thousands of cases per year. That is no alternative at all. We don't let children die because it is fatiguing to save them. Our commitment as a foundation is to work with partners until no children die from polio.”

“Unfortunately, many programs are so big that there is no one individual who really knows all the pieces, and so the amount of code sharing you get isn't as great. Also, the opportunity to go back and really rewrite something isn't quite as great, because there's always a new set of features that you're adding on to the same program.”

“We're no longer in the days where everything is super well crafted. But at the heart of the programs that make it to the top, you'll find that the key internal code was done by a few people who really know what they were doing.”

“Understand that this is the last physical format there will ever be.”

“There are no significant bugs in our released software that any significant number of users want fixed. ... I'm saying we don't do a new version to fix bugs. We don't. Not enough people would buy it. You can take a hundred people using Microsoft Word. Call them up and say "Would you buy a new version because of bugs?" You won't get a single person to say they'd buy a new version because of bugs. We'd never be able to sell a release on that basis.”

“If you just want to say, "Steve Jobs invented the world, and then the rest of us came along," that's fine. If you're interested, Jim Allchin will be glad to educate you feature by feature what the truth is. ... Let's be realistic, who came up with "File/Edit/View/Help"? Do you want to go back to the original Mac and think about where those interface concepts came from?”
