In search of a biological crux for AI consciousness

Whether AI systems could be conscious is often thought to turn on whether consciousness is closely linked to biology. The rough thought is that if consciousness is closely linked to biology, then AI consciousness is impossible, and if consciousness is not closely linked to biology, then AI consciousness is possible—or, at any rate, it’s more likely to be possible. A clearer specification of the kind of link between consciousness and biology that is crucial for the possibility of AI consciousness would help organize inquiry into the topic. However, I argue, proposed views about the relationship between consciousness and biology tend not to capture a link that is crucial for the possibility of AI consciousness. In addition, I offer a crucial thesis, namely the biological requirement according to which being consciousness at least nomically requires having biological states.
