You've got plenty of examples of how the command line is more than jus a "cool" way to do things. So I'll address a couple other issues.

On windows you are discouraged to use command line because that way windows gets more control over what you can do or can't do. Remember windows is not a neutral piece of software, it's a company's business model. On Linux there's no reason to impede using the command line, all the power to you.

(because let's be honest, it makes us feel superior)

I don't know if it's because of my autism, but this strike me as odd. Do people really think like this? I have a certain expertise, that's computers, and I can use a bunch of different tools to the best of my knowledge to do things. I choose command line or GUI depending on how easy the task is to do in each or the time it takes. Not everyone is trying to show off, it's just the best tool to use sometimes.
