I got tired of people complaining that it was too hard to use UNIX because the editor was too complicated.
The reason I use ed is that I don't want to lose what's on the screen.
I think the Macintosh proves that everyone can have a bitmapped display.
Today scientists, technologists, businessmen, engineers don't have any personal responsibility for the consequences of their actions.
But no, I don't generally have trouble with spelling mistakes.
I had almost rewritten all of the display code for windows, and that was when I gave up.
