Big Oil Faded. Will Big Tech? (Today All of Exxon Is Worth Less Than Jeff Bezos)

In general Amazon, with the exception of AWS, isn't really a tech company. It's a retailer/logistics company which made a critical bet in automating it's operations.

Even it's Kindle operations is just value-added for their retail branch.

In that sense Amazon is not a tech company like Microsoft or Google or Facebook. Amazon's business, with the exception of AWS, consists of selling goods and services through an online catalogue. You see a product, click click and it's delivered to your door step it a couple of days. Controlling the entire logistics network that delivers products from the factory to the door step of any regular Joe is a line of business that doesn't depend on tech excellence.
