But I think this lack of optimism is just another facet of negativity bias. I know a lot of people who say they're not optimistic, certainly - but all of them can point to massive social improvements made recently, and most of them have a clear vision of other things they hope to accomplish within a couple decades. They just prefer to express this vision in terms of how much things suck now or how terrible it would be if they don't improve. You can say "let's create a greener world together", or you can say "we've gotta stop greedy fossil fuel corporations from ruining the planet", and nowadays people seem to consistently choose the latter.
