I saw this thread and thought as I clicked, "I wonder if anyone's posted.. oh, good."
You've got some moderately highbrow and transhumanist stuff in there; have you tried Greg Egan? The two starting places I like to recommend are the Clockwork Rocket books (natives of a universe with alternate physics explore it and figure out what's going on, kind of Flatland turned up to 11.. and then up to 121..), and Permutation City which I think will meet your "some very interesting ideas" and then keep accelerating.
I think demand for legendary armor is high and sustainable enough that the situation may continue pretty much indefinitely. The grind required is huge, and a lot of people are undertaking it with great enthusiasm, and looking at the examples provided by other legendary equipment supports the claim that interest will hang on more or less indefinitely. I'm still constantly running into people who want to do raids to work on that armor or Coalescence, fractals for Ad Infinitum, etc, and those projects have been available for years.
Note that I'm using the word 'may' here because all this is wild speculation about what players will do en masse; it's not a hill I'm going to die on.
Your analysis stops before you consider how one might actually make money from rifts, specifically by using the essence you loot to make motivations and selling said motivations on the market. Just poking at it casually yielded ~160 gold from motivation sales for me recently, some of which was of course eaten by the other materials needed for motivations. It's worth noting that besides activities mandated by the story, I used zero motivations myself - there are plenty of people tagged up and doing them, and you want t1 and t2 rifts for this purpose more than t3 anyway. I wasn't very seriously trying to make gold with this, just running around with friends who wanted to do rifts for their own reasons or collecting xp to fill in mastery tracks.
Deciding whether this is a good way to make gold relative to other options would require significant work, but that's where you want to go if you want an answer.
Does the cult have a good plan for healthcare? If so, please send me your newsletter, manifesto, religious tract, pentabarf, whatever.
Cataclysm: Dark Days Ahead is pretty astounding, offering an incredible level of detail and degree of freedom, plus just lots of zombies to fight.
You've also got their coverage of the 2016 election, where it's a matter of settled fact that they slept on an FBI investigation of Trump for things we now know actually happened while putting Clinton's emails on the front page at every opportunity.
You've also got them giving a platform to dreck like this - https://www.nytimes.com/2018/01/27/opinion/immigration-stephen-miller.html?partner=rss&emc=rss&smid=tw-nytimes&smtyp=cur - which includes lovely bits like "The foreign-born share of the U.S. population is near a record high, and increased diversity and the distrust it sows have clearly put stresses on our politics."
I'm not one of those people who has accumulated an entire drawer full of examples and is able to provide you with 400 bullet points of what's wrong with the NYT, but maybe two more will help push you to investigate a bit more? The NYT may publish left-leaning content sometimes, but they are not an actual ally of the Democrats, let alone the progressive or far left. They routinely publish Republican lies uncritically, and their perception as left-leaning is one of their best weapons.
