(credit: Meta AI) On Tuesday, Meta AI announced the development of Cicero, which it clams is the first AI to achieve human-level performance in the strategic board game Diplomacy. It's a notable achievement because the game requires deep interpersonal negotiation skills, which implies that Cicero has obtained a certain mastery of language necessary to win the game. Even before Deep Blue beat Garry Kasparov at chess in 1997, board games were a useful measure of AI achievement.
