Indeed, being able to type quickly is invaluable in minimizing the time your mind is blocked from continuing onwards. Or, in general, being able to use keyboard quickly. I've seen a lot of people who, when troubleshooting some issue in a SSH session, are v e r y s l o w in shell (quick sequence of little tasks like: type a command, find a particular command in your recent shell history, bring it back up, change something in it, navigate to a different directory, grep some log output). If even the simplest of those tasks takes you a few seconds, you risk losing the train of thought.
