The artificial intelligence (AI) revolution is beginning to pay off: By 2021, AI augmentation will create $2.9 trillion in business value, and 6.2 billion hours of worker productivity globally, according to a Gartner report released Monday. Gartner defined AI augmentation as a partnership model of AI and humans working together to improve cognitive performance, including learning and decision-making. "Augmented intelligence is all about people taking advantage of AI," Svetlana Sicular, research vice president at Gartner, said in a press release. "As AI technology evolves, the combined human and AI capabilities that augmented intelligence allows will deliver the greatest benefits to enterprises." By 2020, Gartner predicts that decision support/augmentation will be the largest type of AI in terms of the greatest business value add and the fewest barriers to adoption, followed by agents, smart products, and decision automation.
