I used the phrase “fallen state” in the sense that humans could have been better in the past than us today. We make improvement only in technology, not in our behavior pattern. If one’s blood pressure is increasing day by day, we know that it is not a good sign. Similarly, our nations are becoming stronger and stronger as the time passes by assuring Mutually Assured Destruction with the latest being the introduction of Poseidon, the world destroyer, from Russia—https://www.popularmechanics.com/military/weapons/a22537135/russias-nuclear-tsunami-apocalypse-torpedo-is-named-poseidon/).
Even when we make improvements in technology, later we find it was not at all a progress. For example, cell phones used by almost everyone now. Its irregular microwave pulses create disturbing patterns on functional MRI studies. There have been studies that say cell phone microwave energy is often toxic to brain cells.
Lyon, France, May 31, 2011 — The WHO/International Agency for Research on Cancer (IARC) has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group 2B), based on an increased risk for glioma, a malignant type of brain cancer associated with wireless phone use.

In summary, this study provides evidence that in humans RF-EMF exposure from cell phone use affects brain function, as shown by the regional increases in metabolic activity. It also documents that the observed effects were greatest in brain regions that had the highest amplitude of RF-EMF emissions (for the specific cell phones used in this study and their position relative to the head when in use), which suggests that the metabolic increases are secondary to the absorption of RF-EMF energy emitted by the cell phone. Further studies are needed to assess if these effects could have potential long-term harmful consequences. Jama Network 2011

If you say “fallen state” is a myth, opposite camp can say what you say is also a myth as theories are bound to receive jolt occasionally like this: “Mysterious ancient humans with brains like modern people.” https://www.independent.co.uk/news/science/ancient-humans-homo-naledi-brains-intelligence-evolution-behaviour-a8351451.html
