Alexa, Cortana officially become BFFs as Microsoft and Amazon integrate the two assistants

A year ago, Amazon and Microsoft pledged that their digital assistants, Alexa and Cortana, would become friends. That future has now arrived: Beginning today, you'll be able to invoke Alexa from Windows 10's Cortana, and Cortana from an Alexa device like the Echo. Today (or possibly tomorrow, according to a Microsoft representative) Alexa and Cortana will become skills in their respective devices. Put another way, you'll be able to say "Hey Cortana, open Alexa" on a Windows 10 PC or Harman Kardon Invoke. On an Amazon Echo, you can say "Alexa, open Cortana."
