From TFA: "While Amazon insists these reports are “erroneous,” it doesn’t deny that humans aren’t involved with the process at all. Instead, Amazon says its workers are tasked with annotating AI-generated and real shopping data to improve the Just Walk Out system — not run the whole thing. “This is no different than any other AI system that places a high value on accuracy, where human reviewers are common,” Dilip Kumar, the vice president of AWS Applications, writes in the post."

Don't see how this refutes any claim. If anything, Amazon is confirming they have human intelligence involved, they're just leaving the quantity/portion ambiguous, as behooves them. Do you have Amazon equity?
