Any civilization that emerges from either instant catastrophic collapse or resource repletion will be nonindustrial and non-technological, because we have already used up all the shit they need. (Any hypothetical nonhuman intelligence evolving any time in the next 100 million years or so will be in the same situation.)

My prayer to Quetzalcoatl this evening is that we refrain from arguing about what will or won't happen over the next 100 million years.
