Google spotlights AI at Pixel smartphone launch

Google has unveiled a slew of new hardware including two new own-brand smartphones, the smart speaker Google Home and the DayDream VR headset - but its artificially intelligent assistant took the spotlight.

The company also unveiled a new campaign from Droga5 New York promoting the new Pixel phones, called "Life by Google", positioning Google at key moments in people's lives.

Google opened its Made by Google keynote with a new skit from "Silicon Valley", in which two of the key characters get het up over the event.

Perhaps unintentionally comically, chief executive Sundar Pichai then appeared on-stage to discuss the technical nitty gritty of Google's knowlege graph, which underpins semantic search, machine translation, and text-to-speech.

But he hinted at the bigger picture. "We are evolving from a mobile-first to AI-first world," he said. "Wouldn't it be nice if you had a Google for your world?"
