Then you're not comparing old and new software. You're comparing apples and oranges. Neovim is comparable to VS Code in only the most superficial terms.

Oh no. It can be compared in more than superficial terms. E.g. their team struggled to create a performant terminal in VS Code. Because the tech they chose (and the tech a lot of the world is using) is incapable of outputting text to the screen fast enough. Where "fast enough" is "with minimal acceptable speed which is still hundreds of times slower than a modern machine is capable of": https://code.visualstudio.com/blogs/2017/10/03/terminal-rend...
