How fast? Nobody knows
You know me, I have this panglossian faith in human ingenuity such that I think there will be great feats of amelioration … mitigating, postponing, palliating the collapse such that it will unfold over centuries, generations … an incremental bummer punctuated by periods of crisis … characterized by a persistent low-level depression of the spirit with pockets of despair.
But some tell me I’m wrong. They say we’re on the verge and it will be faster than anticipated, dramatic, sudden-horrible.
I don’t know, they don’t know, nobody knows. Steven Pinker thinks things are great and getting greater. But he don’t know.
Maybe we’re seeing collapse at the periphery:
