The discoveries of antidepressants and anxiolytics weren't accidental: testing something and seeing what it does, then finding a purpose for it is not accidental, it's basic science. It's how most chemicals were discovered. And there's no doubt these medications work in a lot of people (but not all), even though we don't understand how they actually work. Our ancestors did not know what fire was or how it worked, but they did use it because it was useful, the same applies here. Further development is going to be difficult without a good understanding of how the brain works, though - pharma companies need to focus on finding better ways to probe deeper and more accurately into the brain (and create good simulators for that later on) before developing new drugs.
