Sprinting is a weird sport. I think it exists because running is a natural human skill that many people care about beyond running contests, because they can't thrive with complete dependence on machines for locomotion. In most people's lives, there are times where the ability to run actually matters.
But the ability to play Go never matters outside of playing Go, and we know who is the best at playing Go.
Ah yes, the ability to use your brain competitively is completely useless in the day to day lives of humans. It's much more important to everyone's day to day life that they can occasionally sprint 30 feet to the bus because they snoozed their alarm one too many times, and that is of course a completely comparable skill to a 100m dash.
