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, [Vista development chief] 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?

The moral systems of religion, I think, are superimportant. We've raised our kids in a religious way; they've gone to the Catholic church that Melinda goes to and I participate in. 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.

Personal computing today is a rich ecosystem encompassing massive PC-based data centers, notebook and Tablet PCs, handheld devices, and smart cell phones. It has expanded from the desktop and the data center to wherever people need it — at their desks, in a meeting, on the road or even in the air.

If people had understood how patents would be granted when most of today's ideas were invented, and had taken out patents, the industry would be at a complete standstill today.... The solution to this is patent exchanges with large companies and patenting as much as we can.

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.

Deploying today’s renewables and improving transmission couldn’t be more important. . . . Unless we use large amounts of nuclear energy . . . every path to zero in the United States will require us to install as much wind and solar power as we can build and find room for. . . . [M]ost countries aren’t as lucky as the United States when it comes to solar and wind resources. . . . That’s why, even as we deploy, deploy, deploy solar and wind, the world is going to need some new clean electricity inventions too.

Usually, you'd expect the worst to be the "ground zero" country — in this case, China, then the next wave, which was all in Asia, and then in Europe, and then finally, the U.S. We had all this community spread. With a travel ban, where you actually force people to come back from China, you have to have a way to be able to either just assume they're infected and quarantine them, or test them. And then if they test positive, to have that enforced quarantine. We actually seeded a lot of infection by saying, 'Okay, everybody, residents and citizens come back (and not testing or quarantining).'

Before Paul and I started the company, we had been involved in some large-scale software projects that were real disasters. They just kept pouring people in, and nobody knew how they were going to stabilize the project. We swore to ourselves that we would do better.
