Psychiatry is useful in the way Statistics is useful for math models we don't fully understand. Statistics let's us get at answers with enough data even though we don't really understand the underlying model at play.

There a whole host of 'sciences' that are kind of 2nd tier like this, Psychiatry being one of them. Once we understand enough Neuroscience, it's likely to me Psychiatry will get consumed by Neuroscience which will splinter into more useful for day to day life categories as it grows (like a psychiatrist)

Super book on the subject and also talks about the rising bar for individual culpability as we understand more about the brain: https://www.amazon.com/Incognito-Secret-Lives-David-Eagleman...
