This is a good article in some ways and a not so good article in others. We do now know how brains compute and we can readily get this "neurodivergent" pattern of computations. But there are many, many, other types of normal "neurodivergence." The stone analogy is good because first no two people can possibly think the same way. It is just not possible.
In the following article is the proof of that, and it comes from the computational cognitive neuroscience of lies.
Language is a window on this computational divergence. But the divergence is both nature and nurture in complicated ways. Darwin put it best when he noted that as you go down the tree of life to individual species, the competition for survival grows more severely in detail. Life of the same species compete against each other more than life of different species. Essentially worms are more "neurodivergent" than a worm and a man. However, for metazoans, animals with brains, we see that all brains compute in fundamentally the same way because neurons, diverse as they are, all do the same thing for a living.
We see this clearly, not so oddly, in the computational cognitive neuroscience of natural language.
(P.S. I always tested about the same on the three types of neurodivergence noted in this article. There are many many other types. You can go for hours listing different types of human genius. I'm a Ph.D. in this stuff. We are still a ways from operational definitions of every form of 'neuroplasticity' but are getting there. Read Terry Sejnowski (one of our greatest minds on this stuff: https://www.amazon.com/Deep-Learning-Revolution-audiobook/dp/B07MM8F42R/.)
But the stones brick analogy is a sweet analogy. The Tower of Babel idea is good and bad. UNIVERSALS of natural language are empirical facts about all the different natural languages humans speak. It is this common compendium of observable facts that reveal the most about how neurons compute. We are far more similar to each other than the Tower of Babel would imply. We are not just stones, we are all stones. Studies of vision computation and other modalities neural computation are simply not as rich a resource in the details of universal metazoan computation as language. This includes visual computation, motor skills computation, and many many others including emotional, social computation, and such. Literally thousands of natural, necessary, inevitable, and evident skill variation evident between your ears. Look to what you can talk about, and lie about, to see how people are different and the same.
Here is another hugely important type differentiation but this is almost purely nurture, not nature, yet just as incurable, once learned for survival:
All these differences are computed by what amounts to the same computer architecture. They are all stones of uncountable diversity.
