There is this famous YouTube content creator named James Rolfe. He does the "Angry Video Game Nerd" and other creations as "Cinemassacre". He is about 40.
In the last half year or so, he has uploaded a few videos where (allegedly) his three-year-old youngest daughter has created "Mario Maker" levels for him to try to beat. We don't get to see any of the "making of" (only him trying to beat them), and he does sometimes remark that "I think her 7-year-old sister helped her out a bit with this one", etc., but still, this blew me away when I saw it.
I'm ashamed to say that when I was three years old, I could barely walk/speak/do anything whatsoever. I certainly would never have known how to create custom levels for a video game, even if said game obviously is intended "for all ages" and engineered to be easy to use for most normal people. Still, at age three?
Perhaps I was just an unusually stupid boy, but I wonder if I could've done those level even at age 7.
Here are the videos (some start with ads):
I'm not saying that these are any kind of "masterpieces", or that James is making this up, but something about this seems strange to me. I guess it's possible that she might be some kind of prodigy due to being born by at least one parent with great genes, and perhaps these videos are him indirectly bragging about the intelligence of his child, but I was genuinely blown away that such a young kid could sit and create all these levels which (mostly) are actually playable and beatable. They aren't completely random button-mashes, as one might expect from a dog or something! Thought and effort has clearly been put into them, albeit from a very young mind.
Have I grossly underestimated how capable many/most/some such young children are?
