> you waltz in and tell them what they prescribe is wrong and your automated treatment plan is better.

That doesn't really capture the conversation though. Susan specifically said (as you quoted) that it was possible she would use the recommendations of the app. If she took a recommendation that means she agreed it was a better treatment. His question was not whether his algorithm was better than her default prescriptions - because they both agreed that was the case at least some of the time - it was whether it was better enough to be financially worthwhile.
