I think you mean to say that your ability to type at 45 wpm has a minimal impact on your ability to be a good developer. To me, 45 wpm is moderate but not slow. I have seen developers who type at around 10-15 wpm.
I have noticed that developers who are slower typers are more likely to fight back on simple changes and writing documentation. It just takes them more time to do the same amount of work that a faster typist will take. In my experience, slow typer are great at reasoning about the code base and coming up with designs in their head, but poor at writing code and communicating with text either through email/slack or documentation.
People who are not fast typist can be very smart but will always be at a disadvantage when it comes to using the keyboard.
