I wonder whether a continual rear-guard action forestalling collapse would be considered "business as usual" or not. I suspect yes, and that someone sufficiently cynical would say this is what is already happening.

I can imagine alternatives that can't be considered either singularity, collapse, or business-as-usual -- a resource-based economy, for example -- but I don't consider them any more likely than either of the first two. Political trends strongly support collapse.
