The experience of chatting with someone allows for what German philosopher Axel Honneth calls ‘Anerkennung’, basic recognition of the other as unique and meaningful in a way that apps and social networks don’t. It allows for conversational service. From that article:
Conversational Services are about one-to-one relationships with customers, about staying in their context and talking by their definition of value.
It’s great to read your thoughts about the wide field of possibilities that chat-based intefaces open up. I think I will call my chat-based personal assistant “Bash”.
