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.

I think seeking perfection in human affairs is a perfect way to destroy them.

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'm not in any sense anti-Facebook.

Individual web pages as they first appeared in the early 1990s had the flavour of person-hood. MySpace preserved some of that flavour, though a process of regularized formatting had begun. Facebook went further, organizing people into multiple-choice identities while Wikipedia seeks to erase point of view entirely. If a church or government were doing these things, it would feel authoritarian, but when technologists are the culprits, we seem hip, fresh, and inventive. People accept ideas presented in technological form that would be abhorrent in any other forms

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.

We have repeatedly demonstrated our species's bottomless ability to lower our standards to make information technology look good.
