I think I can agree there's a happy middle ground somewhere between "paleolithic misery" and "late stage capitalism climate change induced neolithic misery". Both are extremes of misery of a sort. There's still plenty of suffering now... More if you consider the difference in population between the paleolithic and now.

A global society which works collaboratively to maintain both our modern technosphere _and_ a livable, habitable biosphere. Progress doesn't have to come with all of its current negative externalities -- most of them are driven by short-term profit driven thinking that doesn't take our collective biosphere into account.
