A marketing team deploys an AI to generate social media posts. To measure success, they set the AI's primary optimization target as maximizing 'user engagement' (likes, shares, comments). Initially, the strategy is successful. However, after several months, the team notices that while engagement numbers are at an all-time high, customer sentiment has turned negative, and the brand is being criticized for posting 'clickbait' and overly sensational content. Analyze this situation. What principle explains the divergence between the high engagement metric and the negative impact on the brand's reputation, and how does it apply here?
