I think that's the way science pretty much always goes. For the most clear example look at the unbelievable mountain of information we have on the distant cosmos. Yet it all assumes the homogeneity of physics in the universe. There's no real reason to believe this is true outside our sample of 1, but without believing this it would be basically impossible to study the cosmos, because we'd have no way to assess differing physics in distant locations, at least not until we are able to reach those locations and carry out experiments.

Drugs are also the same with many, if not the majority of drugs having come from things that were initially intended to treat something else, only to find out what you created has stronger effects elsewhere. The most obvious and amusing one being that Viagra was meant to be a heart medicine. It turned out to have little effect on heart disease, but had a rather pronounced side effect in half the participants!
