The outfit evaluations consider fit, color, and personal preference, which Amazon could easily use to recommend you items from its growing apparel shop. That's not to say that it can't notice other stuff about users, like changes in body shape, complexion, and any number of other physical traits. The specific AI recipe driving the algorithm remains a secret, so one wonders how whether Amazon might use the Echo Look to undercut its e-commerce competition. If Alexa can recognize clothes from Target, for example, could it recommend instead that you swap it out for something from its own service? From a security standpoint, Echo Look users will have to make peace with putting a camera and a microphone in their bedrooms, connecting it to the internet, and giving Amazon the ability to get some data from it.
