So, Autocomplete, Lang Server and Copilot.

I don't use any of those, and I've never felt the need for them really. Is Make and Vim not an IDE?

None of those existed when I started to code at my first dayjob and I've never really seen the value in them.

I find it interesting you think that go-to-definition isn't possible without a language server. I was doing that long before lang servers existed.

When I want to look a function signature up, well there's two ways I do it.

1) vim + ctags and Ctrl-] will take you there (usually, sometimes it gets confused).

2) grep (or nowdays, ripgrep) the codebase for the name of the function (in another window).

As for remembering what is where. Good organization helps. After time I tend to develop a mental model of what is where and I'll just find myself popping over to the other terminal and opening a file in vim to find what I need.

You can take syntax highlighting from my cold dead hands, though.
