If VS Code is an endpoint to incremental improvements in text editing, then the next big thing that appears will involve a revolutionary approach.
Like in unix tools or other text editors?
I used to think like that but imho when you learn Vim registers it totally makes sense, plus if you're using it in a terminal emulator you can use ctrl-shift-c ctrl-shift-v. Now about Emacs I don't have much experience, but Doom-Emacs and Spacemacs use the System's clipboard by default.
Solving a boring problem better is a thing new technology often does.
