The last resort of every peace process is an appeal to our common humanity, so I do think there is some risk to tinkering with what it means to be human. Look at the state of conflict today, even with the benefit of us all being one species. We figuratively dehumanize our opponents in order to justify violence (“they’re monsters!”). It could get a lot worse if we find ourselves in conflict with people who can be literally dehumanized, with whom we have lost the most fundamental thread of commonality.
