IDEs like VSCose are only powerful because they integrate coding tools like LSPs and completion enginea. Those tools are also available on neo/vim or Emacs, so you can be as proficient as you were with VSCode. Hell, even GitHub’s Copilot is available on vim!
And frankly, having started coding on Atom before switching to neovim, I find a keyboard centric, mode-based coding much more efficient than a usual mouse-centric workflow.
It really boils down to personal preference, but I’m eager to find some objective arguments proving that “vim is outdated when it comes to ease of use”, because that’s not what I experienced.
You’re in for a treat, it’s a PITA to configure if you’re learning it (especially on the UI part, I found). Good luck on the journey :)
