Echos and Homes are natural-language understanders that remain on in people's rooms. I know I didn't cite Google except via YouTube. Google Fi, Google Voice are...who knows, but I'm pretty sure your call contents are available to them. But by "more" I didn't necessarily mean a superset; I meant a greater amount of stuff: your email, your postings, your messages to your friends, when you do stuff, where you've been, etc.
