I'm afraid I am less utopian. To me it seems more likely that we will eventually overreach our productive capacity by wasting time on the "unhelpful" problems I mentioned above, and then enter a period of decline. The best we could hope for in such a situation is that we realise the immediacy of the "real" problems, and start to focus on those, arresting the decline before it becomes too severe. I have an (unfounded) expectation that the process of switching our (i.e. humanity's) productive capacity to focus on the "real" problems would be characterised by cooperation rather than competition, because the adversity required for progress would already be there, and we wouldn't need competition to create it. If humanity becomes more fragmented during that process (see the rise of the isolationist right around the world), then we would run the risk of that cooperation being focused on destructive goals - that would seem to me to be along the lines of the worst-case scenario. It strikes me that a lot of that is my interpretation of some of what is in Joseph A. Tainter's "The Collapse of Complex Societies", which I saw recommended on here, and subsequently read. I heartily re-endorse the recommendation (I did a search to see if I could work out whose recommendation it was that pushed me to read it, but I'm afraid I can't work out which it might be, for which I apologise).
