So basically you can use Alexa via an Echo device to control a Sonos speaker via a skill. Well that doesn't make Sonos an AI home assistant by any stretch of the imagination.

Human: "Alexa, have your people send a request to the Sonos people asking if I can listen to my music on one of their speakers in my living room"

Alexa: "Okay, I'll play "YMCA" by the Village People."

Human: "@#$%ing moron device!"
