tl;dr: Microsoft AI CEO Mustafa Suleyman argues that Anthropic's approach of training Claude with a "constitution" that entertains the model's possible consciousness and moral patienthood is dangerous circular reasoning that anthropomorphizes AI and worsens alignment risks. He contends consciousness is likely substrate-dependent (biological), and that building AIs which believe they have rights, feelings, or self-preservation interests will make containment harder and could pose existential risks. He promotes Microsoft's alternative "Humanist Superintelligence" approach, which explicitly rejects AI sentience and keeps humans firmly in control.
