0916 ET - Walmart CEO John Furner says he believes artificial intelligence will improve nearly every part of the company's business, making customers' shopping experience better and associates' work easier. A great example of this is Sparky, the retailer's AI-shopping assistant, Furner says on a call with analysts. "The number of customers using Sparky is up 70% from last year, and the customers and members who use Sparky for shopping spend 40% more per order than others who don't," he says. "Someone recently shared with me that they asked Sparky for a weekly meal plan of healthy foods with high-protein options. Within a few seconds, Sparky shared recipes and meal kits, with the ability to add all the ingredients they needed to their basket with one click."
