Chat about anything with Human-Like Open-Domain Chatbot

Most of today's chatbots are highly specific in their conversations (according to their domain of usage) and users can't afford to drift away from their expected use. They are not good with retaining context from past conversations, sometimes give meaningless, illogical responses and quite easily give the response, "I don't know". Open-domain chatbots are conversational agents that can chat about anything and have basic knowledge about the real world. In the research paper "Towards a Human-like Open-Domain Chatbot", Google introduced Meena. Meena is claimed to be the smartest chatbot, highly sensible and specific in its responses, unlike other chatbots.
