An out-of-control spacecraft is hurling towards an asteroid. Engineers onboard argue the only solution is to invent a laser that will blast a tunnel through the asteroid so that the spacecraft can continue safely its out-of-control trajectory.

Its an insane strategy. Predicated, among others, on the impossibility of getting back into the control room and charting a non-collision course (which among others will ensure we can better handle any future sustainability challenges). I would challenge that assumption (but with a caveat).

The obstacles you mention are real and in a sense currently as complex to model and work through. Its the difference of socially engineering the complex system that is human society versus biophysically engineering the complex system that is the Earth's biosphere.

Social change is intrinsically easier and far more comprehensive insurance: There is a lot of precedent of purposeful social change and the enormous historical diversity of socioeconomic structures points out to very flexible systems. The obstacles you mention did not even exist a few decades ago. There is nothing deterministic about the current state of the world. Its all in our freaking brains, a lot of it just inane over-consumption because for a while the answer was... why not.

The caveat is that a minimum amount of social change needs to be truly global. This is something unprecedented. We are living through a historically unique moment where the random walk of political and socioeconomic evolution folds onto itself: its canvas is now a finite manifold. Cherished behaviors, power games etc may no longer be part of the solution space.

Remains to be seen how our complex system will adapt.
