The only pessimism warranted is that people can't differentiate experimentalism from failure. Empirical data on failure is under-valued. Just like how academics never publish all the shit that goes wrong. Tons could be learned/saved from publishing negative results. After all, its all in the interpreation. Having bad empirical examples heightens contrast and differentiation, which is often a good thing.
