I loooooved the electricity

I loooooved the electricity metaphor. So simple, so powerful. Except that "exploring and creative" use of electricity will, uh, kill. Without pushing the metaphor too far, while we might not need to know everything that electricity can do, we should at least take a good look at where it can go wrong, especially on inexpert, childish hands. Same with letting kids lose in the Internet with no supervision or no empowered teachers.
