I've said some stupid things and some wrong things, but not that. No one involved in computers would ever say that a certain amount of memory is enough for all time.

Polio's pretty special because once you get an eradication, you no longer have to spend money on it; it's just there as a gift for the rest of time.

I'm a big believer that as much as possible, and there's obviously political limitations, freedom of migration is a good thing.

If you believe that every life has equal value, it’s revolting to learn that some lives are seen as worth saving and others are not. We said to ourselves: “This can’t be true. But if it is true, it deserves to be the priority of our giving.”

The world today has 6.8 billion people...that's headed up to about 9 billion. If we do a really great job on vaccines, health care, reproductive health services, we could lower that by perhaps 10 to 15 percent.

You can go overboard in how quickly you might expect new technologies to transform people's lives. But I very much believe the way software is used, the way information gets distributed, will be dramatically different within 10 years. There is fire to go with all this smoke.

Microsoft does not dominate the software industry by any stretch of the imagination. We have lots of very able competitors who keep us constantly vigilant, and sometimes they beat us to the punch. Microsoft's success to date is based solely on the fact that people like Microsoft software.
