This might work for making reservations at hair salons that don't have an online booking system, but for companies that can obviously afford an online system and are forcing people to call in to increase friction, what prevents them from blocking this service (and similar) for "security reasons"? After all, the AI discloses up front that it's an AI, and lying about it might be dicey. Concerns about security aren't unreasonable either. Basically all companies authenticate you via random pieces of information about you or your service, like your birthday, or address. If you're providing all this information to a chatbot, it also means there's a treasure trove of information scammers can use to compromise accounts or do a password reset.
