Caton in Overshoot called humans a detritus species. Your very descriptive paragraph might be mined for metaphors. For example, in place of a brain, does humanity have going a peristaltic action connecting mines to landfills?
tldr; I've never read Overshoot either but I thought the post had an interesting perspective
That said, if you really can’t tell, does it matter? Shouldn’t we be judging comments on their content, not on who (or what) we think wrote them?
I believe a hint of metaphor there compares humanity as a whole to a relatively autonomous process. If 'Caton' does not clarify a frame for you, compare a pessimistic Adam Curtis. Caton enters as a riff on 'detritis'.
