And yet, we don’t use touch-tone menus, bots that suck are already commonplace. An LLM bot could stand to dramatically improve the user experience, and would probably use the same resources that the current bots do.
Simple things like “I want to fill a prescription” or “I want to schedule a technician” or “do you have blah in stock” could be orchestrated by a bot that sounds human, and people would prefer that to traversing a directory tree for 10m.
I don’t even want to think about how someone would implement a customer facing inventory query using a touch-tone interface, let alone use that.
