Some of the problems have to do with science itself and not the social systems.
Progress in fundamental physics is stuck because of the difficulty doing experiments. CERN is thinking about building an even bigger accelerator that might be done by 2070. It is very possible that it discovers no new phenomena but instead puts a few more digits of accuracy on certain parameters of the standard model at great cost. I think experiments like
are the most interesting area because there really is deep mystery in the neutrino sector and it is important to push the bounds on proton decay. However it is still a story of building bigger and bigger machines and not getting a definitive result like
