After years of promise, more and more businesses are realizing the benefits of artificial intelligence (AI) and machine learning. A 2018 survey showed that 47 percent of companies have integrated at least one AI capability into their business process – up from 20 percent in 2017 – and 71 percent plan to increase their AI investments in the coming years. Change is coming, but that doesn't mean a rise of the machines. Yes, it will mean job changes for some employees: 120 million workers in the world's 12 largest economies may have to be retrained over the next three years (2019–2021), but AI won't replace humans. Instead, industry experts say, AI can help humans make more efficient and transparent decisions.
