I hear you. Liu's outlook is deeply pessimistic. His obvious scientific background knowledge seems to be infused with a dash of western, neoliberal ideology-- that it's just dog-eat-dog out there, and we're all in it for our own self-interest.

It's a bit ironic considering Liu is Chinese- wasn't China's Ming Dynasty the first to land on America in the early 1400s and historically demonstrate that exploration and discovery weren't necessarily accompanied by colonization/enslavement/destruction?

That example gets held up a lot when mainstream historians spin the narrative that Colombus et al enslaved/raped/pillaged because that's just what societies do (while ignoring that it was the debt that the explorers owed to their financiers that drove most of that bad behavior).
