Amazon is disrupting at least 5 industries; the culture of innovation combined with deep pockets makes it clear why Amazon will be the retailer to watch in any category. Amazon.com has been tiptoeing into the world of brick-and-mortar retailing for some time now. The 1,800-square-foot convenience store called Amazon Go that uses a simple premise of the proposition that you simply scan an Amazon Go phone app at an entry gate, shop for whatever you like and walk out the door. No checkouts, no card transactions, no bagging. Amazon key is designed to allow in-home delivery when a customer isn't there!

Amazon's general counsel, David Zapolsky, had a lot on his mind last month when he and four members of his legal team visited the offices of New America, a liberal-leaning think tank in Washington. The retail juggernaut was days from announcing its $13.8 billion purchase of Whole Foods, a deal that would not only roil the grocery industry but also trigger a government antitrust investigation into the strategies and practices of the "Everything Store."

Is amazon getting too big? Is this good or bad? Who should be worried: consumers, government, competitors, everyone, or no one?
