Completely agree with you with the actual crypto state right now when it comes to philosophical point of view - dark clouds hiding everything. I like the comparison to the feudalism, although I find it just descriptive the modern world. Majority of the people live in the modern form of slavery and the most sad part is that majority of people out of their softness don't do anything to change. Just accepting the responsibility for their life on the basic level is something they will never accept...
Anyway I will order the book as it hit my attention and what I usually do is that I respond to book recommendation with another book recommendation - judging by the vibe you could like The Forest Passage by Ernst Jünger. More or less can be percieved by some form of nonconformist's manifesto for everyone feeling uncomfortable with the state of so called western society today. Guy lived up to his 102 years, even after taking a part in WWI, just that sometimes can point to the fact that he could have things sorted out in his head. Altghough the book lacks the technological side, definitely it deals with topic of people being robbed of their fundamental rights to be free and addresses regarding social issues.
