With the damage to, and ultimate burial and abandonment of, Göbekli Tepe, there can be no doubt that the solar-induced dark age – SIDA – had begun. In terms of material artifacts, primarily large megalithic structures from pre-SIDA times remained. Pockets of humanity survived in isolated spots where the natural geography and resources were relatively hospitable. A good example is the Cappodocia region of modern Turkey where the soft volcanic bedrock was conducive to the excavation of extensive underground shelters and indeed entire cities, providing protection from the occasional solar outbursts that most likely continued for centuries or millennia after the close of the last ice age, somewhat analogous to the aftershocks following a large earthquake.
It would be 5000 to 6000 years before civilization would reemerge.
I think that even if we end up disproving these hypotheses, the gestalt message of 'prepare for planet-wide catastrophes because they do in fact happen' is a good and salient one. Something as relatively small scale as a Carrington event could potentially set us back decades if not a century of technological development because our systems are not hardened or redundant.
