Here's an interesting experiment Google is kicking around on its smart displays: voice-command input without a hotword. A video detailing the feature is up on YouTube from Jan Boromeusz, a Nest Home hacker who has a proven track record of scoring early smart display features before they get announced. Boromeusz's Nest Hub Max is somehow in "Dogfood" mode, which means it receives early, non-public builds of the smart display software meant only for internal use at Google.
