Can you quantify this? E.g. through https://typing-speed-test.aoeu.eu/?lang=en
I don't know how fast you think.
FWIW I find that my quicker-than-average typing is still definitely not always fast enough to keep up with what I want to write down.
My "cruising" typing speed is about 80WPM and I don't think I ever feel like I'm typing too slow, for instance while writing this comment I never felt like my mind was getting ahead of my fingers. Maybe I'm a bit slow in the head, who knows...
