And I'm sure there are people who program in Notepad or nano. If you want to develop software like it's the 80s again, go ahead, the rest of us appreciates at least basic IDE support.
Not liking auto-complete is a far cry from nano. I like syntax highlighting, I like on-the-fly type checking, I like linters, etc.
I use Neovim and tmux because I value snappy performance, and never having to leave the keyboard.
The reason I don’t like auto-complete is that it interrupts my thoughts. Once I’m typing code, I know what I want to do, and having things pop up is distracting. Before I’m typing, I’ll think about the problem, look at other code in the codebase, and/or read docs. None of that requires autocomplete, nor would it help me.
If you like autocomplete, great, use it, but don’t assume that it’s a binary choice between plaintext editing and Copilot.
I program in Vim, after having tried multiple IDEs and finding them all to be annoying. In the few places where they were helpful, they only highlighted what I disliked about either the language or a particular library.
