The "witch" comment reminded me of the shift in the term "hacker" to refer to criminal behavior. A lot of people distrust cleverness. I've always suspected that if another term was adopted for positive hacking, such as "tinkerer", it too would be shifted to have a negative or criminal connotation.

It was frustrating that in high school, whenever any computer shenanigans went down, I would always be the one who was automatically called to the principal's office. And some of those times, I wasn't even the one responsible. ;)
