Careful. You're in a linux-heavy audience. They're the kinda people who would spend a few weeks setting up systems to use it for a few minutes.

Who doesn't want to go through learning of text editor and pain of configuring instead of actually coding?

That's fine too. Use whatever does the job for you, but give alternatives a try if you ever have the time.

Well, if you learned emacs, you could do everything in it and won't have to change ever again! /s kinda

Same reason why a carpenter should learn to properly use hand tools, or a teacher should keep up on literature. In other words, master your tools. It doesn't matter which tool you use, provided you can use it to its full potential.

I occasionally use VSCode, but I mostly use ViM because that's my tool of choice.

For another reason, if your ever in the situation where you need to work on something on a remote server or an unfamiliar machine, knowing ViM means you can at least be somewhat productive when you don't have your normal tools available.
