The study of the LBAC is compelling these days because of the similarities to our present day situation. Other commenters have noted the the possibility of AI driven collapse, but another possibility is our dependence on oil.

Bronze is the combination copper+tin. Copper is common in earths composition, but tin is much more scarce. The scarcity of tin necessitated the expansive trade networks to acquire the resource. To my way of thinking this correlates to our dependency on oil which while not exactly scarce, is not evenly distributed across the world. Our global supply chain for oil is fragile in the same way that the supply chain for tin was to the bronze age empires.

As for the article: I found the authors use of dating systems inconsistent and confusing. Some references are listed with the BC/AD nomenclature while others omit it entirely leaving the reader confused as which era he is referring to. Also, the use of the BC/AD has been supplanted by the use of the BCE/CE nomenclature in scientific references for 20+ years. This could simply be due to the fact that the author is a historian, but one would think a PhD would know better. All of this made me wonder if perhaps the author relies too heavily on AI.
