AI is developing fast, but regulators must be faster Letters

The recent open letter regarding AI consciousness on which you report (AI systems could be'caused to suffer' if consciousness achieved, says research, 3 February) highlights a genuine moral problem: if we create conscious AI (whether deliberately or inadvertently) then we would have a duty not to cause it to suffer. What the letter fails to do, however, is to capture what a big "if" this is. Some promising theories of consciousness do indeed open the door to AI consciousness. But other equally promising theories suggest that being conscious requires being an organism. Although we can look for indicators of consciousness in AI, it is very difficult – perhaps impossible – to know whether an AI is actually conscious or merely presenting the outward signs of consciousness.
