How long did you try using Vi (or any other “mode-switch vietnam-era editors with cult like followings”)? Have you experimented with any starter kit/distribution/config (or whatever) to ease you in? What do you use now?
Btw, I agree that stand-alone Vi probably is too far of a departure from modern IDEs. As far as I know, it’s not even possible to give it IDE-like functionality apart from a few basic ones. Both Vim and especially Neovim do a better job at bridging the distance. FWIW, Vim only exists like for three decades now, while Neovim’s first release happened in 2014; almost 10 years ago.
