  1. Rethinking the Redlines Against AI Existential Risks.Yi Zeng, Xin Guan, Enmeng Lu & Jinyu Fan - manuscript
    The ongoing evolution of advanced AI systems will have profound, enduring, and significant impacts on human existence that must not be overlooked. These impacts range from empowering humanity to achieve unprecedented transcendence to potentially causing catastrophic threats to our existence. To proactively and preventively mitigate these potential threats, it is crucial to establish clear redlines to prevent AI-induced existential risks by constraining and regulating advanced AI and their related AI actors. This paper explores different concepts of AI existential risk, connects (...)

    Is moral relativism a good explanation of the existence of widespread moral disagreement?Xin Guan - manuscript
    Moral disagreement arises when two agents assign conflicting truth values to a moral statement, such as whether lying is ever permissible. While moral universalists argue that such disagreements result from at least one party being mistaken about an objective moral truth, their approach faces an epistemological challenge: the need to identify the true moral theory. In contrast, moral relativists claim that the truth of moral statements depends on the perspectives of attributors, enabling coexistence but raising questions about how to justify (...)

    Are current AIs moral agents?Xin Guan - manuscript
    In the following essay, I will argue that the current AIs are not moral agents. I will first criticize the influential argument from sentience accounted by Véliz. According to Véliz, AIs are not moral agents because AIs can not feel pleasure and pain. However, I will show that moral agency does not necessarily require the ability to be sentient and refute Véliz’s argument. Instead, I will propose an argument from responsibility. First, I will establish the truth that moral agents necessarily (...)

  4. Is AI intelligent because of its instrumental rationality?Xin Guan - 2023 - Dissertation, University of Oxford
    This thesis argues against the claim that AI is intelligent due to instrumental rationality, refuting both the reduction and emergence thesis. It contends that intelligence cannot be reduced to instrumental rationality and highlights issues in AI development and application. Instead, it proposes the motivation adaptation approach, where intelligence arises from network of generative motivations and the ability to adapt. This alternative is conceptually intuitive, avoids counterexamples, and provides clear development goals and foundations for ethical development. Thus, the thesis concludes that (...)
