I've used emacs successfully for decades without using LSP or Eglot. Tell me what I'm missing.

I had tried it some years ago and found that it was way more trouble than it was worth, had much overhead, and it was just adding chartjunk (visual noise). I've been happy with syntax highlighting for the last few years. Didn't even have that for decades (I'm old enough that my brain is a compiler,LOL).

I have built a new development computer and installed emacs 31 and I'm open to the possibility that I'm denying myself some useful tools. But everything I've read assumes that you know what eglot/lsp does useful - and I do not.
