Learning vim was what convinced me that it's worth your time to learn tools. Far too many tools present themselves as "no manual required". It would almost be laughable for a phone app to require reading a manual, for example. But even developers these days refuse to read and just expect it to be obvious. What you end up with is VS Code, some of the good parts of vim, but still so far from what's possible if you spend the time to really learn your tools.
