Here are three technology breakthroughs that are acting as catalysts, along with four core roles of AI that are driving it forward. In 2011, IBM Watson, competed in the game show Jeopardy! It was a watershed moment not because the machine beat humans at their own game, but because the possibilities opened our eyes.

In 2011, IBM Watson, competed in the game show Jeopardy! It was a watershed moment not because the machine beat humans at their own game, but because the possibilities opened our eyes. What followed was a series of striking breakthroughs in AI -- image recognition, speech recognition, and many more -- all possible through a technique known as deep learning. As we step into a new decade, an entirely new picture of the future of AI emerges. Heading into a new decade, AI looks more like "AI-as-a-service," embedded into seemingly everything and almost invisible.
