Vim can be turned into an extremely powerful IDE that runs entirely in a terminal, that is incredibly powerful because, it makes it possible to do software development on any computer.
Emacs is a program without peers, there is nothing quite so extensible and powerful out there, there is no way you can replace it with an IDE.
By the way neither vim not Emacs ever were the default editor, that has been and still is VI or nano. Both of these are objectively inferior, and are chosen as good enough minimum. VI is something like a predecessor of vim.
Both VIM and Emacs are also the king of efficient work flow, if you can memorize enough key-bindings, you'll run circles around somebody using something like vscode.
While there are legit reasons to use an traditional IDE, it does not depreciate VIM nor Emacs in any way. Their are tangible benefits to using them instead.>>15726>argument from fortune 500 fallacy (derivation of authority fallacy)
You are making the argument that capitalists who have the most money, for some reason know better how to produce software, fortune 500 means the best at making money, not quality. But the reality is they do not make the best software. They are monopolies that make mediocre products.
