I'm only now learning of the PO model myself. But it's just a more quantitatively rigorous way of stating what I've always suspected, which is that this shit cannot last.
I always thought we'd nuke ourselves out of the picture. Or failing that, we'd run out of some vital piece of the clusterfuck puzzle, and the machines would run down, and the trucks would stop coming, and we'd all wander off into the woods and die.
I grew up in sprawlburbia and was free (to an extent probably unknown to kids today) to range all over the light-industrial wasteland of single-story, single-use, ticky-tack boxitecture.
Even a kid can look at that and realize it won't last.
Here's a blog that shows exactly how right I was about my developmental stomping grounds.
All this growing up doomed may have fucked my head up, but at least I didn't feel shock, panic, and paralysis when I finally got clued in about PO.
The OMG feeling was more like excitement because I'd finally stumbled across a real theory of what was going to pull my native habitat down the shithole. I knew it had to be something, and I had a feeling it was going to be sooner than we were told. PO didn't and doesn't panic me. It's more like the thrill of recognition. "So THIS is what's gonna fuck us! Great! I knew something had to do it!"
