The document discusses the evolution of language and communication technologies towards more natural interfaces using chat/text. Key points include: - Chat/text provides a low cognitive load interface that is well-suited for quick communications between humans, humans and machines, and machines. - Examples of human-human communication include messaging and gig economy platforms, while human-machine examples include digital assistants like Siri, Cortana, and bots. - As the lines between human and machine communication blur, interactions may not reveal whether the reply comes from a person or AI. - This evolution provides a new paradigm for searching and accessing information and services using natural language conversations.
