Yes: FDA approval of the technology and at least one of hospitals, clinics and other healthcare providers adaptation of the technology.
That's not how the FDA works. If they approve AI for diagnosing anything, it will be for one disease or closely related family of diseases. (Even that will take multiple years.) Then they'll do another disease or family of diseases. Each one will have its own multi year clinical trials.
"AI is primary method for diagnosing diseases", as in, most or all diseases, will not happen for at least 10y, even assuming every AI trial goes amazingly well.
@LuisCostigan My reading was that either hospitals, clinics, other healthcare providers, or some combination thereof must adopt the technology broadly. I agree the wording is unclear though.
