He's so good it's exhausting. Btw, life ain't zero-sum. Your skill isn't dependent upon how many grandmasters there are. If someone this good suddenly disappeared tomorrow, would you notice an improvement in your coding? Similarly, you are not any worse just because someone exceeds you. They don't have the power to set *your* goals. They cannot tell you how small you are. Only you can do these things. If you think you have to type this fast and have this intelligence to be "big," you are mistaken.

You have excellente problem solving-skills and you are very good at algorithms. I will not say that you are a programmer acording to this video. Whats is impressed, is note the code itself (you are very fast) but your capacity to think strongly fast. You are amazing for your age and i would be not surprised to see you win a gold medal in informatics olympiad. but it doesn't mean that you have strong knowledge about the structure of memory, about how works a computer. I say that only to clarify some commentaries that i have read.
