"Bardi’s analysis of Tainter’s work extends the argument he first explored in his 2017 peer-reviewed study, The Seneca Effect: When Growth is Slow but Collapse is Rapid. The book is named after the Roman philosopher Lucius Annaeus Seneca, who once said that “fortune is of sluggish growth, but ruin is rapid.”
Bardi examines a wide-range of collapse cases across human societies (from the fall of past empires, to financial crises and large-scale famines), in nature (avalanches) and through artificial structures (cracks in metal objects). His verdict is that collapse is not a “bug,” but a “varied and ubiquitous phenomena” with multiple causes, unfolding differently, sometimes dangerously, sometimes not. Collapse also often paves the way for the emergence of new, evolutionary structures.
In an unpublished manuscript titled Before the Collapse: A Guide to the Other Side of Growth, due to be published by science publisher Springer-Nature next year, Bardi’s examination of the collapse and growth of human civilizations reveals that after collapse, a "Seneca Rebound" often takes place in which new societies grow, often at a rate faster than preceding growth rates.
This is because collapse eliminates outmoded, obsolete structures, paving the way for new structures to emerge which often thrive from the remnants of the old and in the new spaces that emerge.
He thus explains the Seneca Rebound as “as an engine that propels civilizations forward in bursts. If this is the case, can we expect a rebound if the world’s civilization goes through a new Seneca Collapse in the coming decades?”
Bardi recognizes that the odds are on a knife-edge. A Seneca Rebound after a coming collapse would probably have different features to what we have seen after past civilizational collapses and might still involve considerable violence, as past new civilizations often did—or may not happen at all.
"Very little if anything is being done to stop emissions and the general destruction of the ecosystem"
On our current trajectory, he said, “the effects of the destruction we are wreaking on the ecosystem could cause humans to go extinct, the ultimate Seneca Collapse.” But if we change course, even if we do not avoid serious crises, we might lessen the blow of a potential collapse. In this scenario, “the coming collapse will be just one more of the series of previous collapses that affected human civilizations: it might lead to a new rebound.”
It is in this possibility that Bardi sees the seeds of a new, different kind of civilization within the collapse of civilization-as-we-know-it." (https://www.vice.com/en_us/article/8xwygg/the-collapse-of-civilization-may-have-already-begun)
