I have met people who think they understand a particular topic I am versed in, but actually don't. Similarly, I am often wary that I get superficial knowledge about a topic I don't know much about through "laymen" resources, and I doubt one can have an appropriate level of understanding mainly through analogies and metaphors. It's a kind of "epistemic anxiety". Of course, there are "laymen" books I stumbled upon which I think go to appropriate levels of depth and do not "dumb down" to shallow levels the topics, yet remain accessible, like Gödel's Proof, by Ernest Nagel. I'd be glad to read about similar books on all topics, including the one discussed in this thread.
Knowledge is hard to attain...
