The big one in my mind, and I expect his given his other comments as of late, is that there is an increasingly real possibility of WW3 (alongside more ambiguous possibilities of general social disruption). It's still very improbable but WW3 going from nigh impossible to very improbable is about the time you start preparing for the worst and hoping for the best. And if the worst does happen then one of the first things that's going to happen is the internet is going to go poof.

The underseas cables we rely on for the internet are completely vulnerable and there are endless motivations for various sides to clip them for either domestic or foreign purposes: strengthening domestic propaganda, preventing foreign propaganda, sparking social disorder, disrupting communication pipelines, etc.. Satellites, GPS, and so on will follow shortly thereafter.

This exact logic motivated me to recently download Wikipedia. If anybody else is interested in doing so: https://www.kiwix.org/en/ Wikipedia is about 87GB in total with pictures included. I hope that 87GB is just completely wasted and never touched, but the value gained if I ever do end up needing to access it creates a nice risk:reward ratio.
