I'm a two-fingers-and-a-thumb, look-at-the-keyboard, what's-the-home-row? typer, and I can still hit 70+ on a bad day. Still not sure what that has to do with 1) my ability to code, 2) my ability to communicate.
It's just an all-around upgrade to your personal ability. We all spend a lot of time at a computer. Why not try learning? The process of learning touch typing will make you better at two finger typing, if nothing else.
