My daughter came home from school . . .
a few years ago (she was about 8). And asked me if most people are stupid. She had had to help a teacher get a document off a USB stick, powered on a monitor that 'wasn't working' and sorted out some printer issue. She is not a genius but just looks at things logically and starts with the simplest likely problem.
I had to tell her that, "Yes, sadly most people are stupid".
