Hacker Lexicography
I've come to think that there are two main definitions of hacker. I had been concentrating on definition (2), one who hacks. There's also definition (1) which harkens back to the first definition I heard at MIT, one who is passionate about doing something.
A hacker (1) appreciates computers as an intellectual challenge and an art form and feels joy from working with them. ((1) subsequently omitted).
It seems to me that there are a lot of non-hackers, even in IT. These people may use computers, but they do not see beauty in them or feel joy from working with them. They may derive a certain amount of enjoyment, but no true joy, and the enjoyment is likely to be peripheral: the money, the things one can get done, the feeling of "professionalism." A hacker actually loves working with computers; a non-hacker does not.
Hypothesis: the demonization of hackers and the constant confusion with crackers may be due to a distrust on the part of non-hackers toward hackers, a feeling that they must be aberrant, crazy, or inhuman and are therefore "other." Though these people may see nothing wrong with feeling joy at driving a car or playing an instrument, the computer belongs to a special class of machine that they fear and/or loathe, and the people who love them must be bad.
Incidentally, people have objected to the word "cracker," claiming that "hacker" was the original term. Not so. "Cracker" seems clearly a back-formation of "safecracker," which has been around formore than a century. "Computercracker" is a bit much for the tongue, so it is shortened.
