Is a mistake expensive?
If the input is messy (emails, calls, documents, free text), that's where an AI agent earns its place. Reading a support email and routing it. Understanding what a caller wants, like the voice automation platform I built for a company in Germany.
And if a wrong answer costs money or a customer, I put a human in the loop: the agent does the work and drafts the action, and a person approves refunds, price changes or anything customer-facing.
