Slight tangent: I've noticed that robot waiters seem to never actually be doing their jobs, and the presence of one in the store is the sign of the restaurant being poorly managed.
The idea that there could be hucksters selling these door to door to bad managers explains so so much.
Really enjoy the irony that an article complaining about how technology ruined dining shoves a full-page popup in your face while you're halfway through the article.
Not saying you're wrong, but I really think you've overlooked the cultural shift towards individualism.
Maybe not so much in the 1920s, but in WW1 men would lie about their age so they'd have the opportunity to fight for the empire. Family, nation and duty came before self-actualisation and security.
I would not dismiss the link with individualism but I am not convinced that it is a cause, if anything I see it as a consequence. When you are raised as part of a large family with several generations in the same house you probably have a much stronger sense of community than a single kid raised by just two parents.
I don't have PTSD, but do struggle with other health complications.
Focusing on the aspects of your health you can control (diet, exercise, to at least some extent sleep) won't cure you, but it'll make it easier to cope with the problems you have.
If you haven't already, by the way, look into melatonin. I get a couple of bottles of the liquid from a company in the US called Pure Nootropics, and a 0.25ml under the tongue every evening really helps me fall asleep and stay asleep.
I'm guessing you're a fair bit older than me, but from my experience when someone unexpected calls/messages it's almost always a scammer or spammer.
Of course, these people probably only make up <1% of phone users but >99% of unsolicited calls.
I wish we had some better system of just kicking them off of our networks altogether (permabans tied to real name?), so we could get value out of random interactions like the Maasai do.
i3wm achieves something similar on Linux.
