I think these books and resources should not be viewed as hard rules, but as sets of examples explaining guiding principles, and the internet is full of discussions that turn into religious wars over it.

It is always worth it for a programmer to dwell over what complexity is according to Osterhaur; it is worth it to reason over what Uncle Bob thinks is "clean" code, etc. I'm not benefiting from either by applying what they say dogmatically, but I improve my taste in what is good software to me, by discovering and trying many approaches. Without reading them I might never even have thought at a particular solution, or a particular frame of mind.
