There is a vast amount of philosophical progress. But almost all of it is outside philosophy. Jaw-dropping list, just on the topic of democracy; things that Rousseau writing on democracy suffers from lacking:
“Historical experiences with developed democracies
Empirical evidence regarding democratic movements in developing countries
Various formal theorems regarding collective decision making and preference aggregation, such as the Condorcet Jury-Theorem, Arrow’s Impossibility-Results, the Hong-Page-Theorem, the median voter theorem, the miracle of aggregation, etc.
Existing studies on voter behavior, polarization, deliberation, information
Public choice economics, incl. rational irrationality, democratic realism”
