I am the submitter and I am sorry for leaving out, indeed, dismissing the core contribution of the Chilean anthropologists and geologists. The author wouldn't have approved of my editorialising.

I am only slightly relieved that HN have bubbled up a conversation about the self-reinforcing north-south divide in "cultural wealth" instead of making it even more exploitative than it was

Your friend's contribution to the cultural wealth of Chile is ironic. Maybe (some) Southies now have a better (non-fungible/modular) understanding of precision machining, gun-metallurgy or even biochemistry compared to their NorAm counterparts because of his actions.
