a root could be better than us at baseball soccer etc. in the future. Right now, chess is dominated by computers, but 50 years ago, that wasn't even considered a possibility.
Chess isn't a sport

The International Olympic Committee (IOC) defines a sport as a competitive physical activity or game that uses or improves physical fitness and skills. Sports are also meant to be fun and entertaining for participants and spectators.

I've directly proven that chess needs no physical activity, only mental, if it required physical then a piece of metal the size of a potato chip wouldn't be better that every human put together

A piece of metal is better at online chess, not OTB

Just because a definition isn't the most widely accepted doesn't mean its wrong, words ca have many different meanings, and language is complex and nuanced. Therefore, it follows that chess is a sport, because it meets one of the widely accepted definitions.

The IOC recognizes FIDE as the governing body of the SPORT of chess.
