That sounds like an extraordinary claim that would require extraordinary evidence. No doubt physics and engineering have made great advances, but that doesn't mean that every social science that dresses itself up in the language of rationalism will be able to make similar advances, or really any advance at all. In fact, there is a case it will lead to regression rather than advancement:
Societies are very complex things made of people who respond to changing incentives. I don't believe anyone understands them very well, nor has any field in the social sciences established a track record of making highly accurate out of sample predictions, especially for the efficacy of interventions 10, 100, 1000 generations on. Even the simple question of "what keeps a society together?" is still a puzzling one, especially now that post-modern Western societies are disintegrating before our eyes and are failing to even biologically reproduce at replacement levels.
And so we turn to values. At least with values, it is possible to gain experimental knowledge in the laboratory of history. Societies reproduce values and compete with each other as well as with a hostile environment, so long lived societies should have acquired value systems more conducive to social survival.
And I don't think we can make much stronger claims than that.
Certainly someone just imagining stuff or doing some small experiments is unlikely to come up with robust rules for organizing society that will stand the test of time better than what comes from the long lived traditions of successful societies.
