Visual Studio is great for developing on Windows software that'll run on Windows or XBox.

Feels like a dead end to me. The ecosystem has colossal inertia, but it's easy to see the lack of future.

So, you propose to give up on Visual Studio because in 20 or so years maybe Windows and XBox won’t exist? Or?...

Also, speaking of IDEs. There are also Jetbrains’ IDEs and XCode. Can’t speak for XCode, but IDEA offers capabilities that Emacs can’t even begin to approach.

I have already given up Visual Studio because none of my work is intended to run only on Windows and Xbox.
