As artificial intelligence advances, we may face systems that approach or achieve human-like cognitive abilities. Develop a comprehensive ethical framework for determining what kinds of AI systems would warrant moral consideration and rights. Address questions such as: What properties would confer moral status to an artificial being? How would we verify or test for these properties? What responsibilities would humans have toward artificial minds? Consider theories of consciousness, functionalism, and the moral status of non-human animals in constructing your framework. Discuss practical implications and implementation challenges.
