Y2K could indeed have been serious if it weren't for the massive preparation program put into place. Kunstler was wrong because he thought nobody would do anything about it, not because the problem didn't exist.
Exactly.

Millions were spent on preparing for Y2K. The preparations worked.

Now of course, many say that Y2K was a silly pointless panic ... just because they didn't have to use their survival cabin in the hills.

Why Y2K was a non-event was simply all the programmers doing their little bit each in an all hands effort. Similarly, with the upcoming energy shortages, each of us, not just IT geeks, get to participate in this all hands effort. Buy that motorcycle. Move closer to work, turn down the A/C, and so on.

What sucks is the political ruling class want no part of the preparation. Instead, they want to milk the situation until starving throngs come begging to them to be enslaved just to eat.
