I wish we hadn't used all the keys on the keyboard.

I think the wonderful thing about vi is that it has such a good market share because we gave it away.

- Bill Joy

So Chuck and I looked at that and we hacked on em for a while, and eventually we ripped the stuff out of em and put some of it into what was then called en, which was really ed with some em features.

- Bill Joy

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

The fundamental problem with vi is that it doesn't have a mouse and therefore you've got all these commands.

- Bill Joy

It is formatted, and I'm tired of using vi. I get really bored.

- Bill Joy

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

- Bill Joy

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

- Bill Joy

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

- Bill Joy

I think editors have to come out of a certain kind of community.

But with Interleaf I don't even have a spell program.

Bitmap display is media compatible with dot matrix or laser printers.

- Bill Joy

Interleaf is based on the formatting process.

I think it killed the performance on a lot of the systems in the Labs for years because everyone had their own copy of it, but it wasn't being shared, and so they wasted huge amounts of memory back when memory was expensive.

- Bill Joy

Well, limbo is not a good place to be.

I think the Macintosh proves that everyone can have a bitmapped display.

- Bill Joy

Document preparation systems will also require large screen displays.

- Bill Joy

But no, I don't generally have trouble with spelling mistakes.

- Bill Joy

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

- Bill Joy

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