Here's what's next for AI assistants like Amazon's Alexa

The world has already fallen in love with AI home assistants like Amazon's Alexa and Google's Assistant. Anyone who's used a device like Amazon's Echo or Google's Home smart speakers--the physical embodiments of the Alexa and Assistant software--knows that the experience is compelling. Asking for a specific song over dinner, switching off a smart bulb on the way to bed, or setting a timer while cooking all make life just that little bit more pleasant. Perhaps it's no surprise, then, that Morgan Stanley estimates that Amazon has sold 11 million Alexa devices. But anyone who's spent months living with an AI voice assistant will also know that they have limitations, too.
