There are a couple of people in the world who can really program in C or FØRTRAN. They write more code in less time than it takes for other programmers. Most programmers aren't that good. The problem is that those few programmers who crank out code aren't interested in maintaining it.

Interleaf is very nice. I expect there to be a lot of competition for programs like that.

I think multiple levels of undo would be wonderful, too.

Operating systems are like underwear — nobody really wants to look at them.

That lack of programmability is probably what ultimately will doom vi. It can't extend its domain.

The reason I use ed is that I don't want to lose what's on the screen.

Systems are going to get a lot more sophisticated.
