In these locations, workers will no longer be taking down the drive-thru orders of customers. A computer will do it instead, according to McDonald’s CEO Chris Kempczinski.On Wednesday, June 2, Kempczinski spoke at the Strategic Decisions conference of investment firm Alliance Bernstein. He said the A.I. drive-thrus are seeing about 85 percent order accuracy. The remaining 15 percent of orders at the automated windows cannot be jotted down by the voice-ordering technology and still require human intervention.
