Absolutely, I think the author did a magnificent job!. Reading the article, all the intricacies (P/NP, polynomial/exponential, blind test, graph coloring) are quite clear and easy to comprehend.

Here are some gentle articles on the zero-knowledge in case anyone is curious:

This is such a good rule. The biggest things I learned from this thread:

- Stop worrying about how I sound to other people, make as many mistakes as possible to receive feedback

- Stop being over-polite by not correcting others, this is how they get their feedback

As an adult who just started picking up a new language as well as piano, I agree with you. But still, as in the article showed, it might be harder for adults to achieve mastery given the same amount of practice.

I have a hypothesis that given the same practice regime, adults started learning much faster because they had so much more experience with other related things (e.g., another language, years of listening to music, etc) . These knowledge can be transferred up to a certain point. But after that point, the kids do better because they are not bounded by previous experiences.
