EMACS could not have been reached by a process of careful design, because such processes arrive only at goals which are visible at the outset, and whose desirability is established on the bottom line at the outset. Neither I nor anyone else visualized an extensible editor until I had made one, nor appreciated its value until he had experienced it. EMACS exists because I felt free to make individually useful small improvements on a path whose end was not in sight.

I have met bright students in computer science who have never seen the source code of a large program. They may be good at writing small programs, but they can't begin to learn the different skills of writing large ones if they can't see how others have done it.

Now that corporations dominate society and write the laws, each advance or change in technology is an opening for them to further restrict or mistreat its users.

Somebody is saying this is inevitable – and whenever you hear somebody saying that, it's very likely to be a set of businesses campaigning to make it true.

If you can find a host for me that has a friendly parrot, I will be very very glad… DON'T buy a parrot figuring that it will be a fun surprise for me. To acquire a parrot is a major decision: it is likely to outlive you. If you don't know how to treat the parrot, it could be emotionally scarred and spend many decades feeling frightened and unhappy. If you buy a captured wild parrot, you will promote a cruel and devastating practice, and the parrot will be emotionally scarred before you get it. Meeting that sad animal is not an agreeable surprise.

Anything that prevents you from being friendly, a good neighbour, is a terror tactic.
