Some of your problem predictions are 100+ years in the future. I generally regard these as nonsense.
Why?
I don't.
Technology is a function of available energy (Tainter, White, Prigogine), not vice versa.
I find projections of viable sustained fusion nonsense given 62 years of failure to achieve it. Every last single other energy source tapped by humans, sustained nuclear fission included, had previous exemplars occurring on Earth, and was adapted by humans either before history, or (in the case of fission) within a matter of single-digit years of initial attempts.
