Introducing Discussionist: A new forum by the creators of DU

Thanks for the clear exposition, GG.

I'd only offer one small quibble: You have:

"less net energy available for end users like you and me" --> "reduced amount of useful work a civilization can do"

But I'd suggest that a significant amount of the energy burned by the likes of you and me in the context of this 'civilisation' is pure waste, or even worse, dedicated to counter-productive and even self-destructive outcomes. I don't find it impossible to imagine a future very 'high' level of 'civilisation' based on much lower energy inputs (which need of course to be entirely CO2-neutral) operating at much more efficient 'civilisation'-positive utilisation levels than at present. For what size population, and under what type of social organisation will be, of course, not only for scientists, social scientists, financial controllers and associated politicians to decide, if current theories of the potential power of the vox populi indeed apply.
