>Eh, war is simply fun. It’s appealing to males in particular, and our testosterone tends to lock in the intoxication. There’s a reason that Battlefield is one of the most successful gaming franchises of all time

This seems like it's essentializing psychology into core biological elements (with a shaky, uncited relationship to evolutionary psychology) without question. When statements are made this way, don't you think it closes off possible avenues for research beyond the bare facts of war and competition in future societies, at least without genetic modification? I think questions like these should be left open rather than dismissed as "war is fun, testosterone".
