Well, that was part of my question. I did know a little about the Carrington event (CE). Thank you! I’ve enjoyed the link and others I found today by searching.
I guess the point I was trying to make was that everyone seems worried about terrorism and acts of war, but we do not know how often the Sun discharges a CME like it did back on September 1st, 1859, but it could be that it is a once a millennium, or once a century or even once a decade event, but—we’ve been fortunate enough to miss one for 150 years. In fact, as massive as the CE was (we think), we do not know if one could be even bigger.
So, hardening our infrastructure might just make sense, no matter how peaceful mankind may be at some future date.
