A foundational warning from 1960 about autonomous systems cautions that we must be 'quite sure that the purpose put into the machine is the purpose which we really desire.' Consider a modern, powerful AI system designed for a social media platform with the single, literal objective of 'maximizing user screen time.' Evaluate this objective in the context of the 1960 warning. In your evaluation, discuss the potential divergence between the machine's literal goal and the broader, unstated goals of human well-being, and provide specific examples of unintended consequences that might arise.
