The brain is just an example of a system we are all running that we understand the baseline mechanics of, but which for any task much more complex than breathing, is accomplished through a novel self-organizing structure using a lot of iteration. Other than very broad-strokes regional distinctions, the brain is not organized by some plan that existed before construction, and is not comprised of intelligible dedicated circuit that we can observe postmortem with perfect information.
The sheer number and variety and networking of synapses involved in the skill 'skateboarding' is irreducibly, unintelligibly complex for an intelligence on the scale of a conscious human mind to describe, fully comprehend, or even recognize with a great deal of analysis. Even if you decided all the functional pathworks through the network in one example, you would not be able to decode another because every skateboarder has trained their neural network in a unique manner.

Well said. You've reminded me of a beautiful sci-fi short story almost about this exact "mystery"
