Well-spent aid money is saving lives for a few thousand dollars per life saved.

Expectations are a form of first-class truth: If people believe it, it's true.

The Global Fund is a central player in the progress being achieved on HIV, TB and malaria. It channels resources to help countries fight these diseases. I believe in its impact because I have seen it firsthand.

I've been very lucky, and therefore I owe it to try and reduce the inequity in the world. And that's kind of a religious belief. I mean, it's at least a moral belief.

I believe the returns on investment in the poor are just as exciting as successes achieved in the business arena, and they are even more meaningful!

The moral systems of religion, I think, are super important.

I can understand wanting to have millions of dollars; there's a certain freedom, meaningful freedom, that comes with that.

I think that society has to be careful not to shift all of its resources to the elderly versus the young.

The Center for Disease Control started out as the malaria war control board based in Atlanta. Partly because the head of Coke had some people out to his plantation, and they got infected with malaria, and partly 'cause all the military recruits were coming down and having a higher fatality rate from malaria while training than in the field.

The misconception that aid falls straight into the hands of dictators largely stems from the Cold War era.

People are going to buy cheap fertilizer so they can grow enough crops to feed themselves, which will be increasingly difficult with climate change.

Being flooded with information doesn't mean we have the right information or that we're in touch with the right people.

I meet people overseas that know five languages - that the only language I'm comfortable in is English.

The Internet is becoming the town square for the global village of tomorrow.

Technology is just a tool. In terms of getting the kids working together and motivating them, the teacher is the most important.

The first rule of any technology used in a business is that automation applied to an efficient operation will magnify the efficiency. The second is that automation applied to an inefficient operation will magnify the inefficiency.

I think it's fair to say that personal computers have become the most empowering tool we've ever created. They're tools of communication, they're tools of creativity, and they can be shaped by their user.

Information technology and business are becoming inextricably interwoven. I don't think anybody can talk meaningfully about one without the talking about the other.

We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten. Don't let yourself be lulled into inaction.

You know capitalism is this wonderful thing that motivates people, it causes wonderful inventions to be done. But in this area of diseases of the world at large, it's really let us down.

Today, we're very dependent on cheap energy. We just take it for granted - all the things you have in the house, the way industry works.

The trouble with energy farming is that the energy isn't always where you want to use it, and it isn't always when you want to use it.

Well, I don't think there's any need for people to focus on my career.

if I'd had some set idea of a finish line, don't you think I would have crossed it years ago?

I believe in innovation and that the way you get innovation is you fund research and you learn the basic facts.

Security is, I would say, our top priority because for all the exciting things you will be able to do with computers - organizing your lives, staying in touch with people, being creative - if we don't solve these security problems, then people will hold back.

When you want to do your homework, fill out your tax return, or see all the choices for a trip you want to take, you need a full-size screen.

I believe that if you show people the problems and you show them the solutions they will be moved to act.

If you can't make it good, at least make it look good.

In American math classes, we teach a lot of concepts poorly over many years. In the Asian systems they teach you very few concepts very well over a few years.

The trouble with energy farming is that the energy isn't always where you want to use it, and it isn't always when you want to use it.

If your culture doesn't like geeks, you are in real trouble.

I have an excellent memory, a most excellent memory.

I'm going to save my public voice largely for the issues where I have some depth.

Eradications are special. Zero is a magic number. You either do what it takes to get to zero and you're glad you did it; or you get close, give up and it goes back to where it was before, in which case you wasted all that credibility, activity, money that could have been applied to other things.

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.

There are websites that any government wants to block. The truth about the Internet is that it's extremely hard to block anything - extremely hard. You'll never get perfect blocking.

Eventually you won't think of 'the Internet business.' You'll think of it more like news, weather, sports, but even that taxonomy isn't clear.

The part of uranium that's fissile - when you hit it with a neutron, it splits in two - is about 0.7%. The reactors we have today are burning that 0.7%.

A lot of people assume that creating software is purely a solitary activity where you sit in an office with the door closed all day and write lots of code.

If you've found some way to educate yourself about engineering, stocks, or whatever it is, good employers will have some type of exam or interview and see a sample of your work.

The common thread for everything I do is this idea of a Web-services architecture. What does that mean? It means taking components of software and systems and having them be self-describing, so that you can aim them, ask them what their capabilities are, and communicate with them using a standard protocol.

If you count E-mail, I'm on the Internet all day, every day.

If you count E-mail, I'm on the Internet all day, every day.

I don't think culture is something you can describe

Living on $6 a day means you have a refrigerator, a TV, a cell phone, your children can go to school. That's not possible on $1 a day.

You're never going to get the amount of CO2 emitted to go down unless you deal with the one magic metric, which is CO2 per kilowatt-hour.

There is no doubt that as an economy grows in a great way like India has, that you have to step back and change your tax systems, because you start to get more disparities of wealth.

People want to watch whatever video they want to watch whenever they want to watch. If you provision your Internet infrastructure adequately, you can do that.

Should there be cameras everywhere in outdoor streets? My personal view is having cameras in inner cities is a very good thing. In the case of London, petty crime has gone down. They catch terrorists because of it. And if something really bad happens, most of the time you can figure out who did it.
