Like a lot of tech products I think these devices have a niche appeal, despite the fact that of these doohickeys are answers in search of a problem people will buy these products (Target hosted this expo after all).<p>Unlike a selfie stick or edible gold pills however there is a deeper ethical issue inherent in selling products that transact so much data about your life (and metrics about your family and home) for the purpose of creating marketable data sets about every mundane aspect of living. Not to mention how vulnerable a person or family becomes once these devices are integrated into their house, children, car, BBQ, etc since so little attention is given to making these devices secure.
