I didn't know that. Thanks for the info. And I don't know why AI is involved. The NFL has used a version of the challenge system involving replays for years. Those are still judgement calls made by humans - at Wimbledon and in the NFL.
For tennis, I could see a laser-like system to determine if a ball is inside or outside a line. That might already be in use. In the NFL, I could see ball placement done with technology, rather than an official. I'm no Luddite, but only so much judgement can be removed from the game. Regardless, changes are coming.
