There is a contradiction here that I just want to point out because I have been stuck on it myself. The author acknowledges that consciousness is likely a spectrum, I personally feel the same way, but then goes on to say that GPT-4 is "standing right at the ledge of consciousness" Spectrums don't have ledges. I suspect this is because, like me, they are unable to rectify consciousness being a spectrum with GPT-4 definitely not being conscious. But it's definitely a contradiction and I don't have an answer for it. Nor am I ready to bust out a marker and start drawing lines between what is and isn't conscious.
