In particular, it's a fascinating exploration of how a field of thought can get dominated by convenience, and how brushing aside the inconvenient details can produce a structure that is tottering without anybody even realizing it. (That is, everyone knew that the standard model was insufficient, but disagreed about *how* it was insufficient, so the consensus and policymaking formed around that insufficient model.) And it gives some hints of the massive arguments occuring within the field right now, and some of the approaches that are being explored.
Really, it's neat stuff. The conclusion of the article is that these are hard times for economics, and respect for the field has plummeted, but is providing an invaluable opportunity to shake up the field and make it better...
