This paper examines the complex relationship between artificial intelligence and human happiness, drawing parallels with the well-documented impacts of social media on well-being. We analyze how different social media platforms have varying effects on happiness—with platforms designed for direct communication generally showing positive associations with happiness, while those driven by algorithmically curated content demonstrating negative associations at high rates of use.
