The basic calculus is that if you decrease the number of minutes of doctor time enough, it doesn't really matter if they are 100% correct (0 minutes of 100% correct = 0 advice).

Patients are substituting 15 minutes of 100% correct information for 2 hours of 80%, or whatever percentage the AIs are.

Additionally, they're pretty much free at the moment and available 24/7 with no travel required.
