Randomly turning genes on and off to see what they do is experimentation. It leads to a better understanding of genes. Biology is messy and complex, so it's difficult to trace all the causes and effects. But there is some understanding of the mechanisms by which genes turn into phenotypes.
Certainly. And that's great. And often its also great to simply care about, say, gene-drug interactions and not find the root cause.
