I understand the other comments in this post, I too would be allergic to this sort of experience - luxury or not.

However, does the regular "joe/jane" feel the same way? I imagine my mom or dad would most likely not notice or care if they did.

If it’s anything like talking to ChatGPT via voice they’d definitely notice. And if it has anything like the failure modes it does, the OP’s brother is going to eat into a lot of the cost savings he’d get (vs using a human receptionist or even an outsourced receptionist) dealing with fires like the AI said my car would absolutely be done today.
