> people who shouldn't be talking about CS.

Dijkstra said computer science is about computers as much as astronomy is about telescopes.

I am not sure I agree with that, but it's definitely not about text editor choice.

I have a .vimrc file with LSPs and whatnot. But it was from 3 years back. These days I use VSCode and IntelliJ (depending on language) because they do so many things out of the box. I would say the choice of editor is the least consequential thing in one's understanding of "CS" and programming methodologies. On the other hand, using debuggers, profilers, monitoring tooling can have a real impact on how you solve some problems.
