solar flares are predictable with enough notice. If it’s an h bomb, we will have enough problems with or without the empl. So, please stop writing old fashioned fairy tales here.

Is your whole argument that a solar flare will be predicted with enough notice and the grid will be shutdown in time to save us?

Yes. Of course a comet could also annihilate us at any time.

Let's hope it works out that way, and not like this Texas electric grid story.

This is why we don't try to test it, yeah. Black starts take forever in part because there's no solidified procedure for it, but producing such a procedure would require causing the disaster we're trying to avoid.

So far nothing quite as bad as a real black start has yet happened, and here's hoping it never will.
