Because everything else about coding that is not debugging is arguably better in vim/nvim.
I'm one of those. A happy user of IDEs for a decade, but after trying and embracing vim/nvim all the IDEs now feel slow, bloated and clunky. Even with vim/nvim plugins.
Sadly, the FKK seems to be in decline in Croatia. According to Slovenian newspapers the formerly FKK camping sites are slowly transitioning to clothed ones.
For me it is not about the speed of typing or not breaking the flow.
But after experimenting with home row mods and (split) keyboards with multiple thumb keys, regular keyboard layout usage just feels terribly inefficient.
While fast typing is not a bad thing it is definitely not necessary skill of good coder. But coding and using the terminal requires frequently using special keys and combinations, which on regular keyboard require constantly moving hands to access hard to reach keys.
Using home row mods (with a special keyboard) the hands are almost resting.
