Of course I don't know what's going on in that meeting on in the mind of Donald Trump. But I do know one of the things President Barack Obama was struck by was how much time he spent on cyber-security as president. And one of the things he said was that, in the years ahead, the next president will be spending even more time. And cyber-security isn't a thing that goes away after this election. It's a constant flow.

When you cover politics, you realize that knowing how to talk about character matters more and more. The way we hold ideas is more important than the ideas.

[Betsy DeVos] does care about charter schools, which are public schools. She does care about choice, which is a perfectly legitimate thing to care about. It's because it's the one issue where the Democratic donor base was really energized, which was the teacher unions.

We know the 65-point policy points, to the extent that they exist, but is Hillary Clinton willing to be vulnerable, is she willing to be funny, is she willing to be both authoritative, but also real? And so less what she says than the emotional tone she sets. It takes a lot of confidence to be a vulnerable speaker on this stage. And sometimes she hasn't always projected the confidence it takes to be in some ways weak. But that's what I think people were looking for, that moment of human connection.

The roots of great innovation are never just in the technology itself. They are always in the wider historical context. They require new ways of seeing. As Einstein put it, 'The significant problems we face cannot be solved at the same level of thinking we were at when we created them.'

Donald Trump understands sense of belonging. And a lot of people think globalization, any time you make any particularity, you're sort of offending some other group. And a lot of people in this country think they belong to America anymore, and he at least appeals to some sense of belonging. I like the idea that we belong to Western traditions, so I'm glad he appeals to that sort of thing.

If we're in some sort of Hobbesian state of nature, where you just want a strong man who has no compassion Donald Trump is going to do a little better. So, we will figure out what game we're playing.
