I don’t have a problem with anything on vsc - in fact, I use it when I ssh into servers because I like the nice “at a glance” file UI, and I don’t have to cd & ls to see where and what everything is.
Unlearning all the vsc keystrokes, shortcuts, and tools is going to be a serious time commitment, but I’m a young guy and have a long career ahead of me. If vim is really that much faster, I’d be willing to take the performance hit for long term growth.
