How does privacy and security work in this everything-device? Imagine I say: "Buy me a hat like that one!" Then the device is supposed to take a photo (of someone who might not want to have their photo taken), look up my hat size in a personal details database, access my bank account, maybe log into a store account to make the purchase and collect frequent purchase rewards, provide my address for delivery...? And are my actions with the device stored in logs? Where does all that personal information live? Who can access it? I like that there are currently hard breaks between stores, my bank, my personal details, etc. I don't need a streamlined hat-purchasing experience so much that I want to give up all that personal information for it. (Also, it's already annoying that everybody talks on their phone everywhere... voice interfaces for *everything* *everywhere* might not be so great.)
