Until we have a testable, falsifiable thesis of how consciousness forms in meat, it is rash to exclude that consciousness could arise from linear algebra. Our study of the brain has revealed an enormous amount about how our anatomy processes information, but nothing of substance on the relationship between matter and consciousness. The software and data of an operating LLM is not purely abstract, it has a physical embodiment as circuits and electrons. Until we understand how matter is connected to consciousness, we also cannot know whether the arrangements and movements of electrons meet the criteria for forming consciousness.
That’s largely a different topic from the article. Many people perfectly agree that consciousness can arise from computation, but don’t believe that current AI is anywhere near that, and also don’t believe that “thinking” requires consciousness (though if a mind is conscious, that certainly will affect its thinking).
