The global reaction to COVID is highly relevant to this discussion. As with covid the secondary and tertiary effects will be vastly greater than the primary effects.

There is a fascinating logistics and timing feature to this whole topic. Aside from global panic'd masses. There is a huge logistical difference between sudden and unplanned electrical grid shutdown and subsequent black start vs a pre-planned five minutes outage (assuming we can predict impact to five minutes). Another interesting electrical utility issue is the radiological damage from a melted-down nuclear power plant varies exponentially with time... There's a huge difference in expected damage between whacking the coolant pumps a month in advance vs a day in advance vs a minute of warning vs no warning at all just no coolant flow.
