I'm a millennial and I hate talking on the phone, but I don't want to talk to a robot, either. Just give me the damn app with menus and stuff and I'll browse them at my convenience and then pick what I want.
And even if I did want to talk to a robot, I'd rather just use the gadget that I already have for talking into, not yet another thing to lug around, keep charged etc.
