This really looks like the results suggests that UBI is actually not effective at all, but BBC tried to pick the nice bits and emphasize them. If 80% had jobs a year after they wouldn't be shy about it.
I've been using Vim and Neovim for about 10 years now, steadily improving my dev experience with plugins along the way. Still, being a Frontend developer I really have a weak spot for beautiful interfaces like you find in VSCode or Sublime Text, so I've been trying to migrate plenty of times. BUT. Vim is just sooo comfortable to use once you get used to it, so I always ended up going back to (Neo)Vim. Being able to do everything with just a few surprisingly easy to remember/remap keystrokes is not only satisfying, but in many cases really fast as well. Plus with coc.vim and vista.vim there's just nothing useful an IDE can offer anymore.
