I mean that the guy is a genius,
hahaha, genius?, do you really think that implementation, sota, is good?

Any implementation seems good when the amount of money you throw at it makes the bad efficiency irrelevant. Result? SOTA code! World record! In the same reasoning, everyone knows that Windows is a much better OS than Linux, if you throw billions in marketing. And Bill Gates was obviously the best coder that ever existed.
Money can't buy shortcuts in math.
