Being that it's more of a Gen Xer pop-sci book, it's not to "prove smarts", but to share a vibe. It belongs on someone's shelf next to their copies of The Naked Lunch and Aja. Maybe even a signed copy of A New Kind of Science?
I'm not trying to be dismissive. It's just true. Nobody is even ashamed of it, nor should be. It's an interesting and still relevant perspective, but because there's no resolution to this line of thinking, many find it underwhelming. There's no "aha" moment to be found in any of this. Just lots of introspection.
You gotta take the good with the bad though. The tall grass is an easy place to hide.
