At this point the most likely future looks like one where we use all of our resources, wreck the environment, and enter a new dark age. The potential benefits/dangers of AI seem distant in comparison.
Note this doesn't require AGI, just basic machine learning finding ways to push our buttons to make us click more buttons...
To return from such a dark age, seems unlikely.
Ironically one of such plants is Cyperus Rotundus, very useful in times of famine. Perhaps we are living in hyperopic age, where the obsession with economies of scale and controlled environments makes the immediate localized complexity into a high entropy nuisance worthy of destruction.

Your link is interesting, I didn't know about that book!
I don't think that's true: https://slatestarcodex.com/2017/10/15/were-there-dark-ages/
Of course, I don't claim to be an expert myself and can't readily judge which of the two articles is more accurate.
I don't care much of a badass anarcho-primitivist some modern person thinks they are. They may think they would rise to the top like Genghis Khan if only they were free of the straightjacket of civilization and its morality, but almost all of them would really starve to death after a winter or die in a ditch of sepsis.
