An AI can write a perfect email in seconds. Having a real back-and-forth conversation is much harder.

Sarah runs a salon. She has an AI assistant that emails her customers when a slot opens up.

Last Friday, a customer canceled his booking. The assistant sent an email: "We have an opening tomorrow at 2 PM. Want it?"

The customer replied in a minute: "Yes, book it!"

The assistant never saw that reply. The slot stayed open. The customer never got a confirmation.
