Good work. But, how is this useful other than for deception and trickery beside the fun aspect of it all? Maybe im lacking imagination and perhaps this type of progress in mimicking human interaction will actually push more and more people back to the IRL world of person to person communication.
Oh I think it could have all sorts of use cases. For example:
Let's say you need to buy a gift for a friend. If your LLM assistant is trained on all the WhatsApp chats you've had with that friend, it would understand your relationship well and would be able to recommend something accordingly
Or it could also just speed up the time taken to reply to messages by suggesting responses and therefore having you type less
