One example I encountered was with someone I know who mentioned Linux, and I said I use it and he suddenly got fascinated and started asking me how I get anything done when all I have is just a command prompt and how does that work. Somewhere along the way he’d gotten the idea that Linux has no GUI at all and you just do everything in the terminal. Not sure where that idea came from but I was like no dude, it works pretty much like any other OS, it has Firefox and Chrome and stuff. I think he was a bit disappointed lol.
