You lost me when you started narrating the fossil doom visage.

With the current progress in solar, as well as the remaining coal, gas and uranium reserves, energy is not going to be what finishes our civilization.

While I don't think we are going to get true collapse, I think we are going to get a lot of technical progress compensating for biosocial deterioration.

The demographics, mental health and dysgenics are all real, quantified trends, and we are going to face the reality of less capable, less taxable population for the rest of this century. It's baked in at this point.
