Back at her clinic in Long Island, Dr. Mariwalla is thankful for the information that the artificial intelligence system can provide. For the patient with that blistering skin condition, she took the machine’s suggestion for an alternative medication. The patient has recovered, Mariwalla says, but she's careful to add that she made the call herself—based in part on her conversation with her patient. "That's where medical judgment comes in," she says. "You can’t [just] rely on a system to tell you what to do."
