In a sense this is a way of saying that in epidemiology, the failures are noisy and successes are silent, so comparing large epidemics across history might be misleading.

the comparison makes no sense because the diseases are radically different. Ebola kills so quickly and is so infectious that it is self-limiting: patients die before they can spread it very far. Whereas AIDS patients can spread the disease for years, though it is as weakly infectious as as contagious disease can be.
My impression is (and I have not studied this) the failure in the HIV epidemic (pandemic?) wasn't a failure to develop drugs, it was a failure to perform basic epidemiological interventions to learn about and slow the progress of the disease.
