I am not optimistic. What we learned from history is that despite all warnings and good intentions, governments, corps and citizens will make every possible mistake before we finally arrive at another precariously stable situation. Experts are famously bad at predicting the outcomes of new technologies/policies even in times of relatively low upheaval. And plans have a way of producing many significant unintended consequences. This is not going to prevent people with strong opinions from asserting that they know exactly what needs to be done. And in the rush to do something many things will certainly be done. We are screwed at least for a while.
