When someone has something like a learning disability which is relative to what we consider normal.
Different brain areas will come up to support his thinking as he struggle.
It takes a lot of energy and capacity.
But with a specific, efficient wiring, the effort is lower, the energy consumption lower, it feels seamless and somewhat obvious. The circuits gets you further faster and saves up other ressources and energy to keep thinking to a higher level.
More capacity left, more time left, more energy left.
You can also process information multiple times through the same areas. Itās not something that you would feel. It would be like finishing laps faster and faster progressively adding more details and complexity to your thought.
The wiring itself allows for the tasks to become more of an unconscious habit, something automatic. The difference between conscious struggling and subconscious mastery canāt be underestimated.
There are many more ways that leads to the compounding effects and it is of course simplified.
Of course, training requires some resistance, after a certain point what has been learned and mastered cannot be learned and mastered again.
