Yes. It's way cheaper. You can get a new CPU for $200, but you can't rewrite VSCode in the time that money would provide.

Why is the only other option to rewrite VSCode? How about another editor? Vim, <space, doom, etc>emacs...?

Okay then replace "rewrite VSCode" with "turn Vim/Emacs into the same IDE experience as VSCode/IntelliJ".
