People can be uneducated about medication, acetaminophen overdose is a leading cause of acute liver failure in the United States. A little bit of a barrier and forced information about the concern might not be a bad thing but it doesn't require a doctor. A lot of medication probably falls in the same category but is on the other side of the prescription fence.

And doctors aren't infallible, AI (and rule based systems) can act as an extra safeguard for them as long as they don't blindly trust it.
