It’s funny, OP. I mean your point #4.
I’m a professor, I teach programming at a fairly high level. I’m trying to convey certain key topics, and I’ll stop and ask the class if they understand, if everything is clear, if there’s any questions.
There is nothing worse than silence.
You’ve got people in the middle of the lecture with their laptops open, playing computer games. They pretend like they’re working but I know, I’m not a dummy.
You’ve got people in the back of the lecture who are just talking amongst themselves. They may be pretending otherwise, but come on.
So sometimes I can stand there, and when I get crickets, I can ask myself, “What am I doing with my life?” Why bother giving a lecture when nobody’s listening?
So if somebody actually has good questions, and we wind up discussing those things… frankly, my friend, that’s awesome. They’re paying attention. That’s what I live for.
Now, if they have idiot questions because they weren’t paying attention, that’s another matter. But that’s still better than silence. Even if you just shake your head at your prof, like no, you don’t have questions, that’s better than just kind of looking like a deer in headlights. Oh, he’s stopped talking, better pretend to pay attention. Derp.
