You're making so many wild assumptions in this comment without any scientific basis at all.

When does having aphantasia mean someone doesn't have a world model? Ditto for an internal monologue? Also the data on subjective experiences is notoriously flaky. I.e. it's highly likely that many people don't even know what an internal monologue actually means when they do in fact have something approximating that description.

Similarly for aphantasia. In fact, you can see a list of notable people with Aphantasia where you can see it includes professional sportspeople, writers, tech founders etc. I.e. you can have no "minds eye" and still reach the highest heights in our society, again, meaning that the mind is still constructing some model of the world and in fact our own understanding of how our brain works is just incredibly limited and basic.

In my opinion, everyone person has a model of the world (kind of obviously) but our brains are more idiosyncratic when we suppose and we represent things very differently to each other, and there is no "right brain" or "wrong brain".
