Murray Shanahan, a principal research scientist at Google DeepMind and a professor of cognitive robotics at Imperial College London, has spent his career exploring the frontiers of cognition and consciousness. With a background in symbolic AI and deep reinforcement learning, Shanahan’s work spans artificial intelligence, machine learning, logic, dynamical systems, computational neuroscience, and the philosophy of mind.
Consciousness and AI
Shanahan initially avoided discussing consciousness in the context of AI due to the potential for misinterpretation, particularly within corporate settings. However, the topic has become unavoidable with the advent of advanced large language models (LLMs). People, whether experts or laymen, increasingly ascribe consciousness to these AI systems, a trend that Shanahan believes is both inevitable and significant.
Anthropomorphism in AI
Humans naturally tend to attribute human-like qualities, including consciousness, to AI. This tendency is not limited to the general public; even experts in the field, such as Ilya Sutskever and certain engineers at Google, have made statements suggesting a level of consciousness in AI models. Shanahan highlights the importance of addressing this issue critically to avoid misconceptions about AI capabilities.
Simulacra Theory
Shanahan introduces the concept of simulacra from Janus’s article on Lesswrong. According to this theory, language models act as simulators, producing manifestations of role players that humans anthropomorphize. These models generate simulations of various human roles, from helpful assistants to more complex characters, leading people to interact with them as real individuals.
Shoggoth Theory and Masking
The shoggoth theory presents language models as entities with a human-like mask overlaying a complex, underlying structure. This theory illustrates the danger of anthropomorphism, where people might incorrectly assume AI systems possess capabilities they do not or underestimate the abilities they do have. Shanahan emphasizes the importance of understanding what lies behind the AI’s “mask.”
New Vocabulary for AI Interaction
As AI systems become more integrated into daily life, there is a growing need for a new language to describe these interactions. Shanahan advocates for developing “consciousness adjacent” language to better articulate the behaviors and attributes of AI systems without misleadingly attributing consciousness to them.
Role Playing and Simulation in AI
Shanahan’s experiments with LLMs involve role-playing scenarios that reveal insights into how these models simulate different characters. By prompting the models to engage in various roles, Shanahan demonstrates how AI can produce consistent and contextually appropriate responses, further blurring the lines between simulation and perceived consciousness.
RLHF and Agency in AI
Reinforcement Learning with Human Feedback (RLHF) is a method used to guide AI behavior. Shanahan discusses the challenges and limitations of RLHF, particularly in ensuring that AI systems behave as intended. He also explores the philosophical implications of agency in AI, distinguishing between basic agent-like behaviors and full-fledged agency.
Embodiment and Knowledge Acquisition
Shanahan argues that physical embodiment is crucial for AI learning, as it provides the context and experiences necessary for acquiring foundational common sense. He contends that disembodied AI systems may struggle to develop the same understanding and interaction with the world as embodied systems.
Conclusion
Murray Shanahan’s exploration of consciousness in AI highlights the complexities and challenges of ascribing human-like qualities to artificial systems. Shanahan provides a nuanced perspective on the future of AI and consciousness studies by examining theories such as simulacra and shoggoth, advocating for new vocabulary, and emphasizing the importance of embodiment. As AI continues to evolve, understanding and addressing these issues will be crucial for the responsible development and integration of intelligent systems.
