A bomb is blown up only once—but one bot can become many, and quickly get out of control.

I think it is no exaggeration to say we are on the cusp of the further perfection of extreme evil, an evil whose possibility spreads well beyond that which weapons of mass destruction bequeathed to the nation-states, on to a surprising and terrible empowerment of extreme individuals.

I think one of the interesting things is that vi is really a mode-based editor.

If you stay up late and you have another hour of work to do, you can just stay up another hour later without running into a wall and having to stop. Whereas it might take three or four hours if you start over, you might finish if you just work that extra hour. If you're a morning person, the day always intrudes a fixed amount of time in the future. So it's much less efficient. Which is why I think computer people tend to be night people - because a machine doesn't get sleepy.

And once an intelligent robot exists, it is only a small step to a robot species - to an intelligent robot that can make evolved copies of itself.

Systems are going to get a lot more sophisticated.

I was surprised about vi going in, though, I didn't know it was in System V.
