JetBrains is not representative of every editor / dev. Language servers mean I can use Emacs / Vim / VSCode / whatever else I want and have IDE features for whatever language I want.
Just as JetBrains is not representative of every dev, neither are LSPs. Some developers want a specialized IDE for their language(s), some want a highly customized editor with their language servers. As long as you efficiently produce code that works, who cares what other people use?
That's a JetBrains plugin. It is just for JetBrains applications, and it closed source, right? Language servers are basically the metric system of IDEs. I can go from Emacs to Vim to VSCode and just use rust-analyzer for my IDE backend.
I don't understand the benefit of using JetBrains specific plugins that only work with JetBrains.
This. I'm using PyCharm with the new UI, and watching my colleagues struggle with VSCode is a bit painful to see. Not saying you can't be productive with it, but why make your life harder than it needs to be?
Tech has an abundance of people who really need to be right in an argument. I've had this same argument with a developer at a client company of mine. Just couldn't let it go when I said I was comfortable with the Jetbrains suite and used their language specific tooling instead of VSCode.
JetBrains users kind of live in their own weird bubble. Of the ones I've worked with, a decent number didn't even know how to use git, they just relied on the built in vcs tools
Almost all of these IDEs have language-specific features in them. PyCharm has Scientific tools (like SciView) for generating graphs using code and data. Rider features a pretty nice Windows Form builder for generating and creating GUIs for applications. Etc.
I can't imagine it being very useful or practical to unload all these language-specific plugins each time you open the program to write in a language that can't utilize those features.
You build workspaces with vscode but the real magic is you never have to switch to visual studio or spend time configuring plugins for a new workspace each time you start a new project
What I am saying is that I don't need an IDE to program stuff. I am fine with VSCode with extensions. With extensions, VSCode can be a multi(programming)language IDE. I don't see the need to have different IDEs for different programming languages. They do have their benefits.
