The world's biggest problems are the world's biggest market opportunities. And that's a huge thing. Solve hunger, literacy and energy problems, get the gratitude of the world and become a billionaire in the process.
With sufficient water on the Moon, solar energy can be used to split the water into hydrogen and oxygen. The oxygen is, of course, critical for humans to breathe and the water important for us to drink.
We live in a world bathed in 5,000 times more energy than we consume as a species in the year, in the form of solar energy. It's just not in usable form yet.
By 2020 the U.S. will be short 91,000 doctors. There's no way we can educate enough doctors to make up that shortfall, and other countries are far worse off.
As I've conducted my interviews with crowdsourcing entrepreneurs and experts, it's constantly hit me that your ability to do something big and bold is really a function of the size and quality of your crowd.
I was seeing a lot of entrepreneurs who were effectively working on the next photo-sharing app. I wanted to inspire them to go much bigger, bolder and more significant than that.
The rate of innovation is a function of the total number of people connected and exchanging ideas. It has gone up as population has gone up. It's gone up as people have concentrated in cities.
The reason I'm an I.B.M.-type guy today is that I really needed a laptop back in 1986, and I just couldn't wait for the Powerbook.
In a way, my father was lucky. He had a hunch that his vision of the National Gallery would interest other collectors and persuade them to come in with him, and that hunch proved to be right.
I had always been interested in markets - specifically, the theory that in financial markets, goods will trade at a fair value only when everyone has access to the same information.
As a philanthropist, I try to help people take ownership. Everything I've done is rooted in the notion that every human being is born equally capable. What people lack is equal opportunity.
I do like to fly under the radar. When I walk around town, the only people I want to recognise me and call me by my name are the folks at Starbucks.
When you have mass surveillance, it's impossible to meet the intent of the First Amendment because reporters can't talk to sources because sources are afraid to talk.
The Fed is the biggest enemy of this economy. In fact, Ben Bernanke, as far as I'm concerned, he's public enemy No. 1. We're never going to have a recovery while this guy's in charge.
Well, there's that girl on the Internet - although this isn't an example of someone who doesn't know they're on - but there's a girl on the Internet who posts one photograph every two minutes from her bedroom.
The factors that have been holding farmers back are similar to those that threaten other types of growth in Africa. Infrastructure and transport are in many cases quite poor, resulting in the losses of huge amounts of produce.
Africa's informal economy is one of the most innovative and inventive environments in the world. Yet it is an environment with little regulation in which workers are often exposed to hard conditions and live without a safety net.
I definitely think there was some overacting on the part of the customers and the wait staff. The people who came in during the shooting were clearly there to have a moment on television, and that's fine.
Just over 800 people were gathered around the cooking stage, all eager to learn about my five-minute flavor cooking. The demonstration had to be done right then and there, in front of everyone.
The 1,000 tasting portions were to be served over a period of six hours, starting at noon, so we would have to prep those another way, to keep them as fresh as possible.
We want to move along and make sure, both internally and externally, that people realize how the company is being run, and it's being run by a group of people now, not just me.
