More of a meta comment than a criticism: there's been a real explosion in interest in mental models this last decade. Mental models have become top of mind in the SV community (and its associated thought leaders), from Farnham Street, Naval, Tim Ferriss, Patrick Collison and many others regularly talking about them and their creators such as Buffet / Munger / Kahneman etc.

What's happening here? Is there some kind of fundamental set of truths we have stumbled upon that make these models timeless and universally useful, or are we just at the top of the hype cycle? Are there cons to internalizing these models, or is this always-relevant wisdom that should be imparted upon all of humanity?

One could also wonder if there's anything new at all to these mental models, or if these have always been universally valid and applicable principles that the community has repackaged in a more polished and condensed format.

Disclaimer: I love this whole subject and immediately bought the book, BUT I'm also somewhat wary of everybody drinking the same koolaid, including myself. Are these truly valuable, or are they purely fashionable, and so people are cargo culting famous SV personalities? i.e. is this the wisdom version of Jack Dorsey meditating and fasting?
