Book: Jonathan Caplan - Not For Disclosure

Has anyone here read this? And if so, any interesting takeaways? It seems interesting, and I'm curious whether it's actually worth reading or if the ideas are mostly familiar territory. I'd be interested to hear what people who have read it thought, particularly if there were any genuinely surprising or worthwhile insights. https://www.youtube.com/watch?v=fAzXqsQdH94 https://www.amazon.com/dp/B0FKYD1YDW
