I don't think AI will make us dumber, it will allow us to work faster and more abstractly. Doctors have no incentive to regurgitate an AI prediction; they're the ones liable for care. Doctors will continue to second guess AI while they use its predictions as one of many data points for their decision.
This is actually kind of what I'm hoping for. The saying is "when you hear hoofbeats think horses not zebras." But that's boring and it turns the doctor into a bored and checked out professional who just constantly sees the same symptoms day in and out and prescribes the same treatment. When something interesting does show up, they're too used to the status quo to actually address the issue.
Let the AI prescribe all of the horse treatments. The doctor can then spend their time imagining more fanciful diagnosis that we're centuries away from teaching the AI how to deal with. Then when the primary treatment fails, instead of trying to convince an overworked and checked out doctor that you've got some other problem, they'll actually already have a list of possible alternative issues that they were really hoping they would get to investigate this time around.
