An AI is playing Pictionary to figure out how the world works

It might be a frivolous after-dinner game to you, but Pictionary could perhaps give AI programs a deeper understanding of the world. AI's lack of common sense is one of the main obstacles to the development of chatbots and voice assistants that are genuinely useful. What's more, while AI programs can trounce the best human players of many games, including chess, Go, and (more recently) StarCraft, mastering them offers only a narrow measure of artificial intelligence. Learning to play chess, for instance, does nothing to help a computer play Sudoku. Researchers at the Allen Institute for AI (Ai2) believe that Pictionary could push machine intelligence beyond its current limits.
