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.
A friend of mine believes similar except it's that everything in Linux doesn't actually work and you have to fix it constantly. It's rather frustrating to deal with.
I spent the better part of my day debugging an python library no IDE issue no flathub issue causing certain shell commands to not run in the IDE's integrated terminal and confusing the living heck out of me. And I use Arch BTW so don't you go around spreading linux misinformation
I mean, there are many of us who live on the CLI and scripting world. Ask him what he wants to do and explain that for anything he wants to do, you can write a script and from that point forward you can do it by typing a word and pressing enter and sitting back and watching the computer do all the work
