I love the idea (OK not really, it is cruel) that people that do not have an internal monologue are in fact NPCs... 🙂
I have an internal monologue, but also have other mental processes - seeing (computer) code in my head in, sort of, multiple layers, and debugging code in my sleep. My monologue comes in writing and reading, and planning what I will say/type, but I also am able to come up with ideas out of thin air without "wording" them through in my head.
