Spit balling:
#1 cost of healthcare
#2 finding qualified, well educated workers willing to work
#3 performance superiority of AI vs humans (which prob varies per field at the moment).
#4 Administrators “following the popular trend for the sake of looking like they are doing something and appear not to be “stuck in the past” (I saw this a lot with early bad, but expensive iterations of EMR in hospital systems) - never, ever underestimate the stupidity of administrators.
I would think providing tailored tax breaks to companies that maintain their jobs would be one option (accounting for the company’s actual savings by using AI).
But #1 is by far the biggest driver right now in the US. Until that is addressed, AI will be very popular as a replacement whenever able. And healthcare carries a inflexible political baggage at present.
