If digital computers are conscious, they are conscious at the hardware level

This article explores the philosophical debate regarding the consciousness of digital computers, arguing that if they are conscious, it must be at the hardware level. The author critiques the divide between physicalist and computationalist perspectives.
Why it matters
As AI systems become more advanced, the philosophical debate over machine consciousness has significant implications for AI ethics and moral status.
Contemporary debate over the moral patienthood of digital minds misses the forest for the trees. Mainstream opinion is divided into physicalist and computationalist camps, who believe that consciousness is substrate dependent and substrate independent , respectively. For this reason, those on the physicalist side frequently make the claim that digital computers will never be conscious . Personally, I consider myself a physicalist , but I’m also a panpsychist – because physics doesn’t really seem to deal in hard absolutes, and I find it straightforward to consider that everything is conscious to some greater or lesser degree – so I’m loath to accept any claims which propose that any specific system isn’t conscious. I think statements such as these are not defensible , and only serve to encourage misunderstanding and even foment philosophical tribalism.
