Does neuroplasticity cancel the notion of "aptitudes" as a natural gift?
To elaborate upon @Rooirokbokkie's comment, neuroplasticity is not exactly like changing computer code, because the brain is not a computer. The brain performs computations, but thinking of it as analogical to consumer CPUs and their Von-Neumann architecture is limiting. For more information on this idea, see "Moving Beyond Metaphors: Understanding The Mind For What It Is" by Chris Eliasmith.

The most important difference is that not everything in your brain is re-wireable. Related questions that explore this are:


Does adult neurogenesis occur only in the olfactory bulb and the hippocampus?
What evidence is there that the adult brain can produce new neurons?
