Yea. I think think the most likely scenario our civilization exists in is that we are coming up on a bunch of Great Filters, and this is just another one of them. There's probably virtually infinitely many (just as life has infinitely many ways to kill an individual or group in pre-modern times). Also, just as in prehistory, it would have taken visionary and moral heroes to build for their future's survival. But today, the role of those who have those concerns is not important in civilization anymore...
