Lol imagine my phone talking with an automated customer service line. Two machines, talking to one another, not using any of the existing protocols. My phone would have a database of questions to ask, form it into an English sentence, run it through a text-to-speech, transmit this to the other phone. Their "phone" would run a speech-to-text, run NLP, match it with its own database, and do the whole thing again in the opposite direction.

This gives a whole new meaning to "all of UI/UX is basically prettifying database queries".
