That's in a large part subjective. For some until we have truly groundbreaking physics with applications which allow doing something considered strictly impossible with previous science, it's not worthy of consideration. For others, just watching slowly unrolling results of decades of development - in electronics (hardware on board of Falcons), computers (organization of that hardware into bigger complex structures, software), organization of enterprises (venture capitalism able to support risky ventures, accumulation of wealth to individuals, ability to optimize for non-immediate or non-financial goals, cooperation with government), methods of material tuning (heat shield, tank bodies, engine) is demonstration enough of the progress being made. We can easily, within few years forget how hard is a particular achievement. Remember how fast Apollo flights started to be considered boring. Or we may turn to those who work on complex problems as we speak, imagine how hard would it be for ourselves doing that and appreciate and honor actual work which leads to these demonstrations. The choice is definitely ours to make.
