Last I checked, an IDE like Android Studio (based on IDEA) needs to download a hogshead of java before it can even begin to build anything. And if you switch compiler versions, it needs to download even more. Sure it makes installing java as easy as clicking a few buttons, and it'd be great if Emacs made it as easy, but still: it doesn't bundle every version. No one would have the drive space for that. And now consider that emacs has support for not just java/kotlin, but pretty much every programming language in existence..

Emacs is not a “modern IDE” and expecting it to be one is a recipe for not only confusion and irritation but also for watering down the goodness that it really is.

Except pycharm won't work with my erlang lsp.
