Other editors don't require nearly the same effort to learn because features are (typically) easily discoverable via the menu bar, or use standard shortcuts. I've never used VSCode in my life, but I bet you a dollar that control-C copies, control-V pastes, and control-F brings up a search dialogue. I also would bet that if I want to split a pane, I can figure out how to do that my mousing around the menu in under ~30 seconds.

Whereas, trying to do pane-like things in vim requires Googling (more efficient in my experience than trying to use the built-in manual) and then reading some stackexchange answer that devolves into a philosophical discussion about the merits of buffers versus tabs.
