I agree, he lost me in the first few minutes by assuming the moment some problems start the society will turn on each other like in some zombie apocalypse.

Anecdotally, I lived almost totally without power (critical institutions had diesel powered stations I think) for months in a childhood, in a city that was not that small (about 100k citizens) in the 1990s in Russia. Nothing much ever happened, no looting, no arson. Police retaliation would be swift, they don't need no computers to punish offenders.
