Atheism and agnosticism are increasing every year. Deaths due to war have been decreasing steadily since World War 2. Some people argue that younger people are becoming less materialistic (https://www.econlib.org/archives/2016/10/non-materialist.htm...).
I’m not sure what you mean by “make us grow more mature”, but there could conceivably be some major technological advancement that would give us enough time to deal with the sociological effects of increased longevity. For example, electric cars are taking over, CRISPR gene editing exists, fusion is moving forward with the ITER project and various start-ups, space rockets are now reusable, etc.
I would say we have more objective reasons to be optimistic about our future prospects than not. Things are getting better, and it might just be that train wrecks and car crashes are more interesting to focus on. No one writes stories about the days that someone gets home on time safely.
