So this guy is a sudoku master. Cus of the diffrenent rules he got to experience what doing a normal sudoku is like for someone for the 1st time.. When u 1st see a suduko, it seems impossible, but then you get one square, and another and so on.
What I think is interesting is that when he 1st saw it, he was like pissed off! He thought it was impossible. I dont think a normal person seeing a normal sudoku for the 1st time would react so negatively.
I think it shows something interesting. That getting super involved in something can make u less open minded about it. You see greater detail but sacrifice your ability to see the big picture. Like anything, its a tradeoff.
