Typing speed might not seem that important if you're looking at the speed of typing and the overall amount of code that an engineer produces that ends up in a PR. But it might take 10x more code that are ephemeral versions that lead up to the full solution. If you're very comfortable with typing and editor commands to manipulate code efficiently then you can iterate faster, creating more intermediate versions of the code that then lead to better overall solutions just because you've tried out more stuff.
