I will take the safest route to a guaranteed cure.
In the absence of a guaranteed cure, I will probably take the option or combination of options most likely to cure me that I can afford.
Whether the AI understands and endorses it vs a human understands and endorses it, is pretty much totally irrelevant to me.
The AI will have a track record at this point for me to make a viable comparison.
Also, why not both options, assuming I can afford it and they're compatible.
I believe AI will invent new treatments in cases where there aren't options, those people will be cured, and using AI medical techniques will become obvious.
