GPT-3, Bloviator: OpenAI's language generator has no idea what it's talking about

Since OpenAI first described its new AI language-generating system called GPT-3 in May, hundreds of media outlets (including MIT Technology Review) have written about the system and its capabilities. Twitter has been abuzz about its power and potential. The New York Times published an op-ed about it. Later this year, OpenAI will begin charging companies for access to GPT-3, hoping that its system can soon power a wide variety of AI products and services. Is GPT-3 an important step toward artificial general intelligence--the kind that would allow a machine to reason broadly in a manner similar to humans without having to train for every specific task it encounters?
