Population of this planet consume resources much faster than they are renewed, it can not last long. Our options are limited - we can continue as now, until real peak oil, peak population, peak production is reached, then kill each other for the leftovers. Another possibility is building a stable society - all the green stuff, birth control, no wars, probably no private enterprises, probably one de facto world government and total control - stagnation. Next is a science fiction dream - we colonise another planets, continue extensive development - wild west all over again, Firefly. The only path that guarantee survival of the humanity in a long run, but the least probable of all - looks like we gave up hopes on this one. And the last option would be to kill that 90% of population, more contagious ebola with longer incubation period? Considering that it is probably much easier to secretly develop bioweapon with cure or vaccine than to create cure in relatively short time - game theory in action, this outcome looks almost inevitable, even MAD not gonna help this time. Why I was telling all this? Because of the bright side - you probably should not worry about future unemployment :)
