“Several days ago, Bloomberg reported that Amazon is considering opening up 3,000 Amazon Go convenience stores by 2021. If you’re not familiar with Amazon Go, here’s how it works: you download an app to your smartphone, hold the app over a scanner when you enter the Amazon Go store and that’s it — anything you buy will be charged to your account, you never go to a register to check out. If you pick something up and put it back you’re not charged. I have been to the store and it works well. Amazon Go is to convenience stores what Uber is to taxis, you leave without having to take any time to pay.”
