From my experience, people are really wary of learning the tool they're using to code, because any editor similar to VSCode fulfills their needs.
However, as you said, mastering a proper IDE is a superpower and allows much more to be done in a single window in a shorter amount of time.
Also, since VSCode is everywhere, getting people off of it, or showing much capable software is a sad and moot effort, from my experience, again. KDEs humble KATE is much better than VSCode on many fronts.
