Begs the question, what kinds of local businesses are structurally safe from being disrupted by Amazon? Some that come to mind:

* Food - restaurants, fast food, pizza, takeout

* Social experiences - bars, cafes, arcades, comedy clubs

* Things that can't be shipped - gas stations, perishables

* Things you want right away - milk, delis, convenience stores

* Things that can't be commoditized - Copying keys

* Services - Barber shops, mechanics
