If you look back 150 years or so the "complex human civilization" which existed back then don't exist anymore. Maybe only in a museum or some buildings here or there. We can now label that replacement by being "evolved" or "transformed" - but the way people thought back then, were dressed, behaved in a social environment, worked or lived is now totally different. Some of those aspects are better now, some aspects got worse. What I want to say is that we can already say good bye to the current way of life because it won't exist in 150 years anymore. Maybe we have found a way that people are not triggered anymore by advertisement to consume things because they are bored with their life. And yes - a lot of things will hit us hard. Maybe we are going to solve it, maybe we will being forced to adapt. A lot of people will die, a lot of people will be born. If we can reach space, then the possibility of 10+ billion people is rather good. But even if we shrink to 500 million it won't be the end of complex human civilization. And to be honest - are you proud of the current form of "complex human civilization" and would it be such a bad thing if it would being replace with something else?
