> No-one likes phone menus and immediately wants to escape them (then they disable pressing 0 for human)

They beat waiting for somebody to answer the phone just to tell you they are sending the call to somebody else and you'll have to explain everything again.

The sequences where you authenticate on the menu and no person is allowed to ask for authentication information makes sense too. I don't think anybody actually like it, but it is better than the alternative.

Nobody likes badly designed menus.

LLMs are replacing a lot of the inflexible phone menus, and in leading implementations, can do all of the things a human could do. Or at least, make a recommendation for things it can't do that just require a human to hit an accept button.
