Maybe for you, but not for most people. Because most people do not behave the way you are describing. Most people express themselves in vague, sometimes incomprehensible ways linked to their cultural and personal background. Their priorities might not be aligned with their best interests at all. Some will even think it clever to hide info from the doc, because they are prejudiced against docs or fear being reported, etc. That's why a skilled clinician is first of all a skilled interrogator, and second an accurate observer. The way you look, behave, walk and talk is very often of more value than lab tests. That's what a good GP is actually: someone good at extracting information from people. An unfortunate consequence of that is that every doc you'll meet will want to hear your story again, which gets old fast for patients.

No, this presupposes that the machine won't interact solely with the medical record, but mostly directly with the patient. At least, that's my understanding. In this view, medical records won't be just text records anymore, but records of the whole system 'sensorium' for lack of a better term.
