There have been lots of tools and resources that have promised (and delivered!) increased programming productivity.

Individual results may vary, but it seems credible that thoroughly learning and using an editor like Vim or Emacs could yield a 2x productivity boost. For the most part, this has never really been pushed. If a programmer wanted to use Nano (or Notepad!), some may have found that odd, but nobody really cared. Use whatever editor you like. Even if it means leaving a 2x productivity boost on the table!

Why is it being pushed so hard that AI coding tools in particular must be used?
