See that's the funny thing. It is probably ripped off of concept designs if anything, because given how long it takes Amazon to turn anything around, you can bet your house on them working on this for a while and it having been waylaid by bureaucracy.
...that's hilarious, as Google Home is a terrible husk of an app that feels like some beta thing written by an intern 5 years ago and they've never went back to actually flesh it out. Settings buried in random menus, no UI consistency, is it a ... menu or a gear to get to settings? Is it for the device or the routine? Oh, how do you get to your camera? How do you reboot your camera? Wait, it controls the thermostat like the Nest app but doesn't quite do all the features of the Nest app? Media controls, sorta! Maybe your TV shows up, maybe your neighbor's Google product asks to join when you launch the app. It's just a mess.
