Re: Technological silos
I think they're hinting about other countries splitting off from the global DNS root, creating their own parallel internet. Possibly going their own way for IP address range assignment too, which would bork the global internet routing table. The USA government is historically had way too much power in this area, though a lot of that has been ceded to international agencies now. Despite that, the USA is still often suspected of still having too much sway over these agencies; which has not been helped by previous attempts at meddling by Trump https://www.theregister.co.uk/2016/09/21/trump_wading_into_iana_transition/. As a result it's a plausible outcome that countries which have a broadly anti-US public sentiment could decide to split off and make their own internet governing bodies, with no US influence at all.
