I don't use the social media but I can see the effects in my own correspondence. I get a ton of correspondence. It used to be hard copy and now it's a very limited amount of actual letters people write. So it's mostly email.

From now on I will consider a language to be a set (finite or infinite) of sentences, each finite in length and constructed out ofa finite set of elements. All natural languages in their spoken or written form are languages in this sense.

I don't know what it means to say that 'the internet should have a voice in Washington'.

Occupy was not a movement, it was a tactic. You can't sit forever in a park near Wall Street. You can't do it for more than a few months. It was a tactic I had not predicted. If people asked me, I would have said "don't do it." But it was a great success, an enormous success, with a big impact on people's thinking, on people's actions.

We have to remember that literally within months after Castro's taking office the planes from Florida were beginning to bomb Cuba. Within a year, the Eisenhower administration secretly, but formally, decided to overthrow the government. Then came the Bay of Pigs invasion. The Kennedy administration was furious about the failure of the invasion and immediately launched a major terrorist war and economic war that got harsher through the years. Under these conditions it is kind of amazing that Cuba survived.

The beauty of our system is that it isolates everybody. Each person is sitting alone in front of the tube, you know. It's very hard to have ideas or thoughts under those circumstances. You can't fight the world alone.
