Yes, we are moving to social collapse but it won’t be sudden. Indications are that it won’t be slow enough to adapt as the mainstream assumption now goes. If we get on this now, planet wide, and with full commitment we could reduce the devastation enough to hang on until we can implement technology to build a new type of civilization.
I’m afraid that the reality will be the worst of both worlds. Too fast for the existing societies to survive but too slow to unite the planet fully to the danger. And from what I’ve seen, the preppers are delusional. They are playing to old movies with no idea what a billion refugees would look like with a steady loss of arable and livable land.
