This is an anarcho-primitivist we’re talking about. They generally believe that the death of over two-thirds of humanity is both inevitable and ecologically desirable, in part because humanity was never “meant” to live in a fashion not hunter-gatherer.
It is worth noting that Jensen has said that while abjuring the Internet et al. would be the “pure” thing to do, he considers that purity pointless and useless, as compared to getting his message to as wide an audience as possible. (So to Anon-e-Moose et al., don’t bother sniping him for using a computer. He already has a counter-argument ready.)
I will confess that a big part of my opposition to an/prims is about how, in a strictly non-technological milieu, Earthly life is supposed to transplant to exoplanets before solar expansion renders it all extinct. It may be billions of years in the future, but this may be our only window to make sure all we do will never be rendered for naught.
