IMO this comment goes too far in the other direction. There is a lot of "natural aptitude" in what we can learn, and more specifically, what we can learn to do well. I can theoretically learn ballet, but I have no "natural aptitude" and so I will never be even OK at it. Similarly, my wife could try to learn programming, but her brain isn't able to make sense of how programming works. The big thing is that just because you don't have "natural aptitude" for something doesn't make you a worse human. It just means your strengths are elsewhere.
