Haha! This grandma didn’t know that behind Google were some powerful algorithms that try to predict the best answer to your request. So she say “please” and”thanks”. Yet, this is really what AI is doing, it is rendering us services, and we shall be more grateful for this.
In the world where AI Assistant is designed to be the perfect 24/7 employee, maybe we could add the rule that the politeness matters; like this grandma : )
