In the academic journal Bioethics, Schiller (2017) writes that ‘The Artificial Replacement Thesis suggests that we should replace our species with artificial creatures who are capable of living better lives’ (p. 393). This kind of argument reflect the typical transhumanism naivety regarding human history: humans have not waited for AI to do just what the replacement thesis describes. We are not fully natural. The invention of language or writing for example allowed humanity to live better lives by becoming more artificial: the proof that language and writing are artificial is that they have, still today, to be learned, while most of us don’t have to learn to breathe (breathing is natural).
