As artificial intelligence becomes increasingly powerful, the question of AI safety and alignment becomes paramount. How do we ensure that advanced AI systems remain beneficial to humanity? How do we align AI goals with human values? How do we prevent unintended consequences from systems that can autonomously make decisions affecting millions of lives?
