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

Systems are going to get a lot more sophisticated.

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.

Given the incredible power of these new technologies, shouldn't we be asking how we can best coexist with them? And if our own extinction is a likely, or even possible, outcome of our technological development, shouldn't we proceed with great caution?

Sometimes the easiest way to get something done is to be a little naive about it.

Take responsibility for the things you build and invent.

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