It missed us by 9 days

Not to undermine the potential severity of a storm... But these are generally events that we literally see coming, and typically have the better part of a week to prep for. And the height of a storm where it would be damaging at ground level is generally a 2-8 hour window (though elevated levels can last a week), and is statistically likely to impact a major population center for only a portion of that time as the world keeps spinning.

Yes, if one somehow caught us off guard, and happened to hit a major population center at 9am on a work day, then it could be absolutely devistating, with decades of recovery time!
But this is highly unlikely to happen. More likely than not we will see it coming 3 days ahead of time, and have plenty of warning to shut down equipment and unplug through the worst of the storm. Still not great. But probably a larger security risk of an enemy attack during that time than any major threat to the grid or the few things that silly humans keep plugged into it.

More importantly, as time goes on and we bury power lines, and have more decentralized power distribution, and move more communications to terrestrial fiber networks instead of slow low bandwidth sattelites, and have battery backups for critical systems, we are becoming ever more hardened against such a threat.
The problem isn't miles long city lines that attach your home to your distribution hub. The issue is the tens and hundreds of miles of straight lines that make up the larger network. Disconnect those, and most cities, especially cities with buried lines, will be able to ride out a storm without having to worry about a blackout unless it is particularly strong. This would leave smaller cities and rural areas without power... Which is inconvenient... But would minimize major economic problems.

So is it a problem? Yes. Will a big one hit within my lifetime? Likely more than one. Will it affect my small corner of the world when it happens? Not super likely. Will we not see it coming and unleash the apacolipse upon the world? No, no it will not. It will be a day long curiosity like an eclipse that will create a lot of buzz! But not likely life altering beyond a weird day.
