In almost every area of human endeavor, the practice improves over time. That hasn't been the case for teaching.

The typical project design time for a large company like IBM - and they keep track of this - is a little over four years.

The world at large is less inequitable today than at any time in history. Number of people in abject poverty, as a percentage, is at all-time low.

Over time, yes, countries will need to look at specific GMO products like they look at drugs today, where they don't approve them all. They look hard at the safety and the testing. And they make sure that the benefits far outweigh any of the downsides.

Bitcoin is mostly about anonymous transactions, and I don't think over time that's a good way to go. I'm a huge believe in digital currency... but doing it on an anonymous basis I think that leads to some abuses, so I'm not involved in Bitcoin.

Fortunately for India, it has got a growing economy. If it is doing the right things with taxation and focusing on the right areas for human development, it is going to have no problem, over a period of time, taking care of its own needs.

I didn't used to wear a watch. Now I have a SPOT watch, which I wear all the time.

We are not even close to finishing the basic dream of what the PC can be. 

I really had a lot of dreams when I was a kid, and I think a great deal of that grew out of the fact that I had a chance to read a lot. 

When Paul Allen and I started Microsoft over 30 years ago, we had big dreams about software. We had dreams about the impact it could have.

Given how few young people actually read the newspaper, it's a good thing they'll be reading a newspaper on a screen.

Software innovation, like almost every other kind of innovation, requires the ability to collaborate and share ideas with other people, and to sit down and talk with customers and get their feedback and understand their needs.

Governments will always play a huge part in solving big problems. They set public policy and are uniquely able to provide the resources to make sure solutions reach everyone who needs them. They also fund basic research, which is a crucial component of the innovation that improves life for everyone.

Energy innovation is not a nationalistic game.

When the PC was launched, people knew it was important.

Microsoft is not about greed. It's about innovation and fairness.

Almost every way we make electricity today, except for the emerging renewables and nuclear, puts out CO2. And so, what we're going to have to do at a global scale, is create a new system. And so, we need energy miracles.

Innovations that are guided by smallholder farmers, adapted to local circumstances, and sustainable for the economy and environment will be necessary to ensure food security in the future.

Innovation is a good thing. The human condition - put aside bioterrorism and a few footnotes - is improving because of innovation.

Harnessing steam power required many innovations, as William Rosen chronicles in the book 'The Most Powerful Idea in the World.'

The tool that's most associated with the recent progress against malaria is the long-lasting bed net. Bed nets are a fantastic innovation. But we can do even better. We can invent new ways to control the mosquitoes that carry the malaria parasite.

I'm sorry that we have to have a Washington presence. We thrived during our first 16 years without any of this. I never made a political visit to Washington and we had no people here. It wasn't on our radar screen. We were just making great software.

Well, no one gives aid to Zimbabwe through the Mugabe government.

Countries which receive aid do graduate. Within a generation, Korea went from being a big recipient to being a big aid donor. China used to get quite a bit of aid; now it's aid-neutral.

I'm sorry that we have to have a Washington presence. We thrived during our first 16 years without any of this. I never made a political visit to Washington and we had no people here. It wasn't on our radar screen. We were just making great software.

There's no such thing as going to a soapbox and saying, 'The government's corrupt,' and not having the intelligence service see your face. In the digital world, that can be done.

Netscape was able to get the government working on its behalf.

Money has always been in politics. And I'm not sure you'd want money to be completely out of politics.

The intersection of law, politics, and technology is going to force a lot of good thinking.

Corruption is one of the most common reasons I hear in views that criticize aid.

Antitrust is the way that the government promotes markets when there are market failures. It has nothing to do with the idea of free information

It's fine to celebrate success but it is more important to heed the lessons of failure.

In inner-city, low-income communities of color, there's such a high correlation in terms of educational quality and success.

Well I think any author or musician is anxious to have legitimate sales of their products, partly so they're rewarded for their success, partly so they can go on and do new things.

Success is a lousy teacher. It seduces smart people into thinking they can't lose.

I think when smallpox was eliminated, the whole world got pretty excited about that because it's just such a dramatic success.

People are always coming up to me and saying, 'I heard your dad's speech, and it's really great.' And they'll mention some place I didn't even know my dad was going to

I think the positive competition between states in India is one of the most positive dynamics that the country has.

 “Success is a lousy teacher. It seduces smart people into thinking they can’t lose.”

 “Patience is a key element of success.”

Our success has really been based on partnerships from the beginning.

Rich countries can afford to overpay for things.

We've got to put a lot of money into changing behavior.

Well private money can take risks in a way that government money often isn't willing to.

Money has no utility to me beyond a certain point.

My mom was on the United Way group that decides how to allocate the money and looks at all the different charities and makes the very hard decisions about where that pool of funds is going to go.

I think there will be PCs at every price point.

If I hadn't given my money away, I'd have had more than anyone else on the planet.

The most interesting biofuel efforts avoid using land that's expensive and has high opportunity costs. They do this by getting onto other types of land, or taking advantage of byproducts that aren't used in the food chain today, or by intercropping.

In low-income countries, getting to a health post is hard. It's very expensive.
