Amazon is invading Apple and Google's home turf in the war over the future of computing

Apple, Amazon, and Google are at war over the future of personal computing, and now Amazon is taking the battle to its rivals' home turf: the smartphone. All three are convinced that voice-controlled virtual assistants have the potential to transform how we interact with our devices. Apple has Siri, Google has Google Assistant, and Amazon has Alexa. They believe that in the future, you won't swipe or manually fiddle with your device -- you'll just talk to it, as you would another human. Whoever gets ahead now has the potential to define the next major era of computing.
