I think this is catching me off guard. Especially in the past 5 years there are Neovim distributions that make this extremely easy to configure.
I am not disagreeing that many (most?) developers don't want to spend time debugging their editor - they just want it to work batteries included (or a simple button click to install). I think this is why JetBrains products are so popular (I still don't understand VS Code - it's the worst of all worlds between vim/emacs and Jetbrains).
But if you've been a (neo)vim user for 20 years, it sounds very odd that you haven't successfully gotten LSP to work in a way that feels comfortable. I don't want to assume things about the author because I do not know them, but it feels unfair to say for vim and doesn't strike me as honest.
