Nature commentary questions the brain-as-computer metaphor and AI consciousness claims

On November 8, The Decoder reported that Seth, Block and Tononi questioned the "brain as computer" metaphor in a Nature commentary and argued that AI should be presumed non-conscious by default. The metaphor shaped modern AI and may also mislead debates about consciousness. The report also covers the Butlin team, which drew on neuroscience theories to propose 14 indicators and found that none of the systems it assessed was a strong candidate for consciousness, though it did not rule out future systems meeting more indicators. That assessment rests on computational functionalism, the premise that consciousness depends only on how information is processed.
