Unsustainable

(From the summary)

"Static societies eventually fail because their characteristic inability to create knowledge rapidly must eventually turn some problem into a catastrophe... history is the history of ideas, not the mechanical effects of biogeography."

TBoI p. 436

"The fact the reliance on specific antibiotics is unsustainable is only an indictment from the point of view of someone who expects a sustainable lifestyle. But in reality there is no such thing. Only progress is sustainable."
