But cars, power tools, and firearms have significant potential for severe bodily harm.

Computers, assuming you're simply using the machine and not trying to stick objects into the power supply, don't. It's ridiculous the fear some people have of simply using a computer.

I remember a line from some short-lived sitcom Tony Danza once starred in. Speaking to his new computer, he says, "You look like a TV, but you're not a TV. You're an evil TV." There's an anxiety and apprehension with computers that, IMO, exceeds the bounds of rationality.
