What changed exactly? Humans are still competing in chess, earning livelihoods, building fan bases. The ELO world rankings don't have any machines because the International Chess Federation only allows humans to enter competitions, just like all the other IOC sanctioned sports governing bodies. I'm sure Boston Dynamics has long been able to make a robot that can run faster than Usain Bolt, but nobody cared and it didn't matter because robots aren't allowed to compete in officially sanctioned track events. Similar to why MLB teams can't use pitching machines instead of pitchers. A Phalanx can't enter a shooting competition. Wrestling federations don't actually allow man versus car like in Rick and Morty's interdimensional cable.

In some endeavors, humans doing it is the entire point.
