I'd be concerned about, it's something I'd call Wii-Sports-ification AI might be able to radically change sports like fencing and HEMA. I could see the development of match judging AIs trained by experts. Anyone who has fenced knows the frustration of the fallibility of human judges. It's also possible that AI judging could benefit martial arts, bringing them closer to their practical roots, by counteracting the rule-gaming competition rules. ("Sport-ification" of martial arts.) Instead of allowing just any touch to count as a point, only hits with enough body structure to allow damaging force could be allowed. Many HEMA competitions try to implement this, but expert calibrated judging AIs would make this an order of magnitude better.
