People have been using text menus, back through early SMS, all the way to dialup in the 70s. Probably before.
But instead of proper menu items (1 for restaurants, 2 for blah blah), then submenus (1 for order, 2 for reservation), there is this strange fascination with natural langiage parsing via text.
Meanwhile, typing '1', then '1' is far better than 'i want to order from a restaraunt'.
Shorter, no mistakes, more precise, easy to use.
Search, such as 'search restaurants' has been a thing too.
I don't want to talk to a machine, which is designed to use as many glue words as possible, and seeks natural language as a reply. What a time waste!
All that politeness is for humans, we don't need it from a bot.
