Yes. A bunch. I worked for a utility, started as an EE eventually became a division manager with about 110 working under me. I found that there’s a lot of just stupid people out there. And then there’s those that are just “dumb like a fox”
But you gotta realize... at least half the people in the world have below average intelligence. That’s simple math.
A lot of these idiots were engineers also.
I worked with a few engineers who were "conveniently stupid". They would come around and ask me things that they should know just because they were too lazy to do it themselves. I told one of them early on that I would put as much effort into this as you do.
