How Do You Know if Someone Uses Vim?

There's definitely a bit of a Vim culture and there are some great YouTubers out there the primary gen is one and you watch him editing and it's just mind blowing. I don't feel that I get a huge productivity boost from using Vim in the same ways as if I'm using an IDE. For me it's kind of I've got my hands in the touch typing position I don't need to move my hands to the cursor key back again to the mouse back again doing that all day long. Maybe for some of the listeners we could go back and give them a bit of context on what Vim is and how to quit it oh can you tell me?
