Yes, for booking appointments, a simple interface might do the trick. However, we've seen many excellent use cases of our API that prevent repetitive tasks and help companies save money, like AI logistics assistants, pre-surgery data collection, AI tutor and AI therapists. I believe the future will bring even more voice interface applications. Imagine not having to navigate complex UIs; you could easily book a flight or a hotel just by speaking.
Also, older people might prefer phone calls over navigating UI interfaces.
As a user, I want to talk to LLMs to answer my random day to day questions. I tried the Retell demo and asked it questions that I had earlier asked Alexa and Google Assistant. The Retell experience was a million times better. I wish I could set it as my phone's (Android) default assistant. If you built that, I would pay good money for it!
However, I agree with others. What I don't want to do is talk to LLMs for customer support. For that, I always want to talk to a real person. It would be infuriating for an LLM to pick up when calling a business.
