They’re both code/text editors, or what would you call VSCode instead? An IDE? you can make an IDE out of nvim if you want.
Yes, there is a vim mode in VSCode, but in some cases it can be very slow (like editing a few thousand columns at once), and is not as tightly integrated.
I find it really interesting that almost all of the recent comments on the YouTube video are 95% the same and praising “how great all this transparency” is, completely drowning out all other comments. They’re also worded very very similarly.
