Evolution has never found a way to be any speed but very slow.

Back in the 1980s, when the internet was only available to a small number of pioneers, I was often confronted by people who feared that the strange technologies I was working on, like virtual reality, might unleash the demons of human nature. For instance, would people become addicted to virtual reality as if it were a drug? Would they become trapped in it, unable to escape back to the physical world where the rest of us live? Some of the questions were silly, and others were prescient.

Separation anxiety is assuaged by constant connection. Young people announce every detail of their lives on services like Twitter not to show off, but to avoid the closed door at bedtime, the empty room, the screaming vacuum of an isolated mind.

Is war an inevitable outcome of competing interests in a complex society? In other words, would war be the same even if human nature were very different? There are mathematical models of large groups working together that lead to conflict on a reliable basis. So there's a whole other view of war that is not psychological at all.

There's no question that males are more violent and more prone to the type of hierarchical organizations that lead to war. War is largely a male activity. In fact, there is some correlation [between making war and] having an excess of males in the population.

In history, in most cultures, and at most points in time, if you want to find the most advanced technologies, you can look principally in two places. One is weapons and the other is musical instruments. My hypothesis is that instruments are usually ahead of weapons. In fact, I think you can find many examples of instruments being predecessors of weapons and very few in the reverse.

I'd much rather see a world where, when you make some quirky comment on a blog or news story or you upload a video clip, instead of just a moment of fame for your pseudonym, you'll get 50 bucks. The first time that happens, you'll realise that you're a full-class citizen. You have the potential to make money from the system.
