Google Assistant is the search giant's answer to other smart home systems like Alexa for Amazon's Echo Dot, and the Assistant AI is separating itself from competitors in a unique way. On top of a focus on things like clarity, recognition and ease of use, the Google Assistant AI is a smart home system with a sense of humor.
Adding humor to AI has multiple benefits. For one, a good joke or witticism from Siri or Alexa might get posted on blogs and social media, raising awareness for and interest in the product. But a funny AI also humanizes the product, making it easier for consumers to interact with it comfortably. As such, Google has hired writers from The Onion and Pixar to give Assistant a better chance of connecting with consumers on an emotional level.
