Child Prodigies

Recently, I've been looking up a lot of the pieces I play or have played on YouTube, and always discover some little five or six-year-old music genius who has already perfectly mastered it. It always gets me down in the dumps, because, obviously, I know that a little kid can play the same pieces I can. But sometimes, though, I have the reassurance from some YouTuber's comment that, actually, the little kid just plays the piece fast, and doesn't actually put any dynamics (that's loud and soft, etc. for all those people who don't know music very well) or emotion into the pieces. So that makes me feel a little bit better.
But, in any case, this brings up the interesting topic of child prodigies. After doing some research, I've found that basically anyone can force a little kid to play well and not stop until they play perfectly, but what actually defines a child prodigy is that they themselves have the ability to play greatly, and work hard enough that they can do well in the music world. This could mean that, for instance, maybe they can play with the same level of dynamics and emotions and near perfection of a music expert, or simply that they can compose some really wonderful music. And I found a video with several comments from people who are very...passionate about the subject of child prodigies. So pay special attention to the comments on the video, but before you do, take a look at the definition of the word "prodigy," then go to the link below and compare it to the comments the people posted on the video:
