Okay, let me put it this way:
The neurotypical brain is a forest. The autistic brain is a mountain range.
In order to learn something, the NT must make a path in their brain. They have to pick their way through the trees, maybe even chop a few down. They can go around tree trunks, they can duck through branches, they can worm their way through the undergrowth. They need to make a path to learn something new but their path is a flexible, organic one. It can be changed, they can take detours, it can be infinitely expanded, hell, maybe even rerouted entirely. This is because their brain is malleable and flexible, like a forest. Thoughts and memories are like animals making tunnels through the undergrowth.
The autistic brain, on the other hand, is made of stone and it's mountain shaped. To form a neural pathway, a new routine, a habit, they have to dig a passage through the mountain, one agonising swing of the pick axe after the other, and it can take years. This is why autistics often have a 'thing' that they obsess over and are sometimes very good at; it's a passage that they've carved out of the rock that they're very comfortable traversing. Carving a passage out of stone is incredibly hard work, and unlike the forest, the path is not flexible at its edges. Up is rock, sideways is rock, down is rock. You've two options, forward and back. To learn a new thing takes a long time and ambiguities really fuck the whole process up.
So you have the NT with their forest brain, and you have the autistic with their mountain range brain. Does that make any sense to you?
