As above, thank you for your work. I came to similar conclusions w/out ever referencing any "movements". I hope many read your words, as they lay out the dots which people can connect if a light bulb goes on.
I would caution that one should always maintain the thought that future events and timelines can never be known. You mention this early a couple times. I think it bears keeping in view throughout your work in order to avoid, as possible, people becoming "disappointed" and have trouble keeping in mind that your ideas are still valid.
I offer one other thought for discussion about likely futures. Powerful institutions really are powerful and they won't disappear, over night or maybe ever. I don't believe in conspiracy theories, they would totally miss the point. But there are millions of people around us and barring true apocalypse (fast and complete) they will continue to be organized by governments and large entities (companies) with control of resources and force. This is not necessarily good or bad per se, but one needs to remember there are large influences out there beyond just the weather. Maybe not overall as powerful as weather, but sometimes much more immediate and very important to not lose sight of. Where this might become most significant is in the case of the "slow future" where society and economy "maintains" while prosperity and well being is rubbed away. It is still important to large entities to make and keep their status quo working. Our huge institutions won't get any smarter or more capable but they _will_ react to their problems, make changes, initiate action. They are not going to disappear. They will, for all practical and foreseeable purposes, always be part of people's lives. Just not in exactly the manner they are now. Millions of people, probably all of us anywhere no matter what our goals or politics, get some necessities of life only through these huge institutions (the biggest of which is the economy itself). Most obviously for everybody, medical care. Then there's basic food for those living in/around large cities.
IOW, in any "slow" scenario it does not seem likely that huge numbers of people (anything over 10%) will die faster than we do now. They will still be here, forming the human environment which we adapt too. The most dedicated Northern Idaho Libertarian will deal with the devil of government in order to get their child doctored and healed. This reality needs to be part of any workable picture. Any far seeing "movement", however true and correct, will always be a small part of a large whole, as long as the mass of the whole exists. I think it will continue to exist and in the Great Scheme, that may be neither good nor bad. But it's certainly an important factor.
Within this country there is one community (well several versions, actually) which seems to have Adapted in their own way: The religious Amish/Mennonites. They live life by their own rules which they believe are the only sensible way because of they see coming down the pipe. They pay taxes. They have created laws which they modify and affirm every year or so about how they will conduct their lives, including how they relate to the rest of us. That includes what tech they use, what help they ask/accept from outsiders, what parts of the "outside" world they can own and participate in. Interestingly, some of their rules relate to courtesy. They have their problems, but the last I checked, about 2012, they were the fastest growing demographic group in the USA. Now, their version of reality isn't yours nor mine, but clearly they are pursuing their own vision successfully w/in a larger whole and this looks like something important for anybody who wishes to form a viable life seriously different from our present economy and society. They have hundreds of years of history and it's been very hard at times; they have moved around through several countries. Worth a look.
