Agnosticism about artificial consciousness

Could an AI have conscious experiences? Answers to this question should be based not on intuition, dogma or speculation but on solid scientific evidence. However, I argue such evidence is hard to come by and that the only justifiable stance is agnosticism. The main division in the contemporary literature is between biological views that are sceptical of artificial consciousness and functional views that are sympathetic to it. I show that both camps make the same mistake of overstating what the available evidence tells us. I then consider what agnosticism means for the ethical problems surrounding the creation of artificial consciousness.
