Sure. But once you know how everything works, you switch back to an IDE. Use the tools that make your life easier, and lose the elitism. There’s nothing more frustrating to me than watching junior engineers struggle to dig through a problem using Vim or Sublime because “That’s What Real Programmers Use”, thinking it’s somehow a crutch to have things like autocomplete or code click through. These tools were built by people far more talented and knowledgeable than you or I because professionals need productivity, not some ephemeral feeling of superiority or nerd cred.
Autocompletions are not limited to IDEs these days. With the advent of editor-agnostic language servers, I have high quality autocomplete in vim, with the bonus of not having to use a slow and clunky IDE.
