Idunno. I think you end up teaching them nothing and just doing it for them. I mentor plenty folks without learning more than basics of vscode/cursor, and the most important lesson for them is always how to figure out how to do stuff (which has never been easier than today).
Yeah, I kinda feel like when you're mentoring people, you should let them drive. If you're going to do it for them, you might as well just record a training video.
