Considering the generational warfare envisioned by the Soylent Green/Logan' War dystopias, it does make a kind of bitter sense that the two generations that aborted so many millions, would themselves be euthanized by the survivors.
Yes, indeed. I hope things will never get that bad (again), but all those “probability” musings are idle conjecture to me (and I’ll stand by that). With a good dash of vested interests (”gimme the research grant”) added.
The human creature has proven to adapt itself to averse circumstances time and again. I do not see why a highly evolved culture (”the West”) - for all its shortcomings - should fail to do so in the next century. It is where most of the current knowledge and technology are concentrated, after all. Some adjustments to current behavior will have to be made.
