Amazon Go

So, the first Amazon Go shop is now open to the public in Seattle.  It's not quite within walking distance of where I work, so I don't know when I'll go - but probably a sign of the future.  No cashiers.  No checkouts.  Just scan an app on your phone that recognizes your Amazon account, and then just take whatever you want from the shelves (mostly lunch type foods) - the store cameras do all the tracking and charge your account accordingly.  Talk about a job killer.  And the quite scary power of Big Brother.  I'm not sure I'm a huge fan of this level of convenience - but perhaps in 10 or 20 years this might be the standard for shopping.  If indeed shopping in a physical location is still a thing.
