"A typical issue that came up was how the book was vetted or checked. In academia, there’s the idea that “peer review” is the ultimate method of checking anything. And perhaps in a world where everyone has infinite time, and nobody operates according to their own self-interest, this might be true. But in reality, peer review is fraught with error, often quite corrupt, and even in the best case strongly biased toward avoiding new ideas and maintaining the status quo. And for a piece of work as large, broad and complex as A New Kind of Science, even the basic mechanics of it seemed completely impractical."
