I've taken to using both vim and nvim, with nvim having copilot. There are times when I'm going in, knowing that I'm re-inventing the wheel, or that I'm refactoring. For those times when I feel like copilot would just get in the way there's vim.

Both copilot and GPT4 have been wonderful 80/20 tools in different ways, and give a remarkable new way to learn.
