Facebook has started exploring the idea of building a digital assistant into its messaging service, but Google might be taking things to the next level with its own artificial intelligence-powered messaging service. According to the Wall Street Journal, the company is developing an intelligent messaging service that allows users to converse with chatbots, which will answer whatever questions the user has, much like Google Search. The Journal claims that there will be different chatbots for different types of questions, and third-party developers will be able to make their own chatbots.
