BetaNews believes that Microsoft has raised the white flag for Cortana, as the company has begun selling Amazon’s competing assistant, the Echo Dot, on its own storefront. While the author claims the Halo-inspired AI “is actually pretty good,” it has drawn little interest from both hardware makers and consumers. ...as a final deathblow to Ms. Cortana, Microsoft is selling the Echo Dot directly. Yes, the Windows-maker is selling a device that outshined its own failed assistant. While it is embarrassing, there is a precedent -- Microsoft also sells the Android-powered Samsung Galaxy S9. Yes, the company sells a device running Linux that helped destroy Windows Phone. Sigh. What's next? Microsoft selling Chromebooks?
