As Amazon is making a foray in healthcare, its dominance in other sectors needs to be understood in context. Read more here. (emphasis mine, below)
Amazon is the titan of twenty-first century commerce. In addition to being a retailer, it is now a marketing platform, a delivery and logistics network, a payment service, a credit lender, an auction house, a major book publisher, a producer of television and films, a fashion designer, a hardware manufacturer, and a leading host of cloud server space. Although Amazon has clocked staggering growth, it generates meager profits, choosing to price below-cost and expand widely instead. Through this strategy, the company has positioned itself at the center of e-commerce and now serves as essential infrastructure for a host of other businesses that depend upon it.
I will not be surprised if Amazon Alexa springs up as a digital scribe for an electronic medical record given away for free. Conversational interface has improved from the earliest iterations. I am not sure if anyone remembers that you could phone Google in the US to get search results by a text message. They used the initial dataset to refine Google Assistant. What would stop Amazon from doing so?
