For a few minutes on Sunday afternoon, Wimbledon's Centre Court became the perfect encapsulation of the current tensions between humans and machines.
When Britain's Sonay Kartal hit a backhand long on a crucial point, her opponent Anastasia Pavlyuchenkova knew it had landed out. She said the umpire did too. Television replays proved it.
But the electronic line-calling system - which means humans have been fully replaced this year following earlier trials - remained silent.
Minutes ticked by. The human umpire eventually declared the point should be replayed.
This time Pavlyuchenkova lost it. She went on to win the match but, in that moment, she told the umpire the game had been 'stolen' from her. She wondered aloud if it might be because Kartal was British.
It later emerged the reason was a more mundane, but still quintessentially human reason: someone had accidentally switched the line judge off.
