What matters is an AI's ability to do things that human combatants cannot, and that which human opponents cannot effectively counter. As you refer to videogame AI, think back to the Berkeley Overmind, a Starcraft 1 Zerg AI that beat seasoned humans by the simple expedient of being able to shuffle around mutalisks [0] in such a way that no human micromanagement could efficiently kill any. The only realistic way to defeat the Berkeley Overmind, as I recall the decade-old coverage, was to attack the AI's base before it could build the tech necessary to spawn mutalisks. [0] Mutalisks are a Zerg air unit whose attack bounces from enemy to enemy. Like all Zerg units, it regenerates health gradually, so the AI's chief tactic of moving even slightly damaged units to the back of the battlegroup allowed surprising compounding benefits.
