Artificial intelligence is slowly seeping into more and more areas of white-collar work. The latest crossover is between tax preparation firm H&R Block and IBM's Watson, with the former using IBM's AI chops to help quiz clients about their tax liabilities. When a customer visits H&R Block to prepare their returns, software powered by IBM will ask questions about their year -- looking for big events like selling a house or buying shares that might introduce tax-deductibles. It's a standard part of H&R Block's service, but the company hopes that by feeding Watson this data (along with answers provided by human tax preparers), they can improve performance across the board. H&R Block's George Gaustello told The Verge that the idea is to share expertise around the company. "We have 70,000 experts, but let's say 500 of those are very knowledgeable about firefighters, or they know every credit deduction a farmer can get," Gaustello tells The Verge.
