Maybe my standards are too low but the fact that we don't have societal wide unrest, mass murders, famine, revolutions and the like that was pretty common just 100 years ago is good enough to provide for an environment where scientific and technological progress can happen.
We have enjoyed 70 years of peace in this corner of the world, but I wouldn't say we've solved the government problem. Give it a couple centuries first, but seeing how the post-war enthusiast has turned into unrest and widening inequality even in this side of the world, I think this peace is "just a phase".
It's hard to see it (and admit it to oneself) because of recency bias and thinking this time it'll be different, that we're smarter than our ancestors but history tends to repeat itself.
