My experience with the healthcare system, and especially hospitals, is that the people working there are generally knowledgeable and want to help patients, but they are also very busy and often sleep-deprived. A human may be better at medicine than an AI, but an AI that can devote attention to you is better than a human that can't.
(The fact that the healthcare system we have is somehow simultaneously very expensive, bad for medical professionals, and bad for patients is a separate issue...)
