I think Trump's attention span is super low. I don't think he has the expertise to actually run a foreign policy.

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.

I learned I'm not a science writer. I'm not very good at describing how something is happening. I try to describe "So What?"

Maybe you're willing to tolerate a lot of bigotry from Donald Trump if you say, just change things, just change things.

Things that change history tend to be organized.

It’s easy to see why politicians would be drawn to the populist pose. First, it makes everything so simple. The economic crisis was caused by a complex web of factors, including global imbalances caused by the rise of China. But with the populist narrative, you can just blame Goldman Sachs.

Some children lack tools to see their course in the world in far-sighted ways. Just introducing school vouchers won't change that. You have to have nurse-home partnerships, early childhood education, mentoring programs and so on. People learn from people they love.
