Many Google Duplex calls come from real people and not from AI.

There are many reasons to rely on human contact. In one case, Duplex did not seem to have known that reservations were available. It may also need training on real-life calls before you can handle all situations. More importantly, the company argued that it was taking a cautious approach. He wants to treat companies with respect, which involves a gradual transition to IA as it becomes more fit to deal with staff.

If the concern is great, it is that Google may have exceeded the capabilities of Duplex. He introduced the technology as capable of handling all kinds of bookings, but this is not always true. There is still a lot to learn, and you might be able to wait a while before you can assume that an AI will handle such tasks.
