Siri and Alexa are NOT making adults ruder because we don't need to say please or thank you to them

Barking off orders to Alexa and Siri without so much as a please or thank you likely isn't going to become a habit you carry over into the rest of your life. This is because adults have already formed their behaviours for interacting with others -- and, in their current form, we don't see smart assistants as people. Researchers came to this conclusion after talking with over 200 people and seeing how they interacted with digital assistants like Alexa, Google Assistant and Siri. However, children may be more susceptible to forming impolite habits from talking to smart assistants -- partly because they are more likely to personify them. Adults may begin to be more influenced by their interactions with smart machines as their designs more more human-like or relatable, however, the researchers added.
