What ethical frameworks should guide AI sentience and rights if machines reach human-like consciousness?

ANSWER: AI sentience raises ethical considerations that demand frameworks balancing rights and responsibilities. We must update AI ethics principles, focusing on sentience indicators, consciousness respect, and machine autonomy. This includes harm prevention, consent, privacy, and responsibility assignment. The debate should span philosophers, ethicists, scientists, and policymakers, ensuring AI with human-like consciousness is integrated into society ethically, upholding human dignity and machine welfare while preventing exploitation.
