All the comments I make on Hacker News are done in good faith and assume good will on the part of the person I'm replying to. If you really think I misread, please rewrite what you wrote; as far as I can tell, I read and interpreted it clearly. It's best if you come out and say things directly, while your statement's thesis isn't entirely clear, but I read it as:
Flies directly in the face of study after study after study that says: diet and lifestyle are major factors in all deadly diseases. <- yes, this is true. However, it's not a useful statement when criticizing medicine based on technology. Even if everybody in the world had a "perfect" diet and lifestyle, it wouldn't address the majority of diseases at a very large scale.
Probably driven by modern tech, completely inadvertently, because x-ray machines and MRIs and such demand that the patient go to the clinic or hospital rather than the doctor going to the patient's home. <- OK, not sure what to say about this other than, it's an unfair comparison; there's plenty of in-home care and in-home doctors can't resolve a wide range of issues at a person's house. It also brings risk to the doctor, as well as causing them to spend their day travelling around.
Star Trek's Dr. McCoy and his tricorder was a dream of tech that you could carry in the proverbial little black bag. We aren't there and have forgotten a lot of important principles in the process of pursuing shiny tech. <- actually, doctors and medical researchers, for all that they pursue shiny tech, still mostly have a good appreciation for "important principles". For example, I watched my surgeon count the sponges that they took out of my spouse after surgery, to make sure they hadn't left any in (this was a surprisingly common problem with surgeries). They don't try to make a "sponge detector machine". That's just one example out of millions; if you've followed doctors on Rounds, you'll see that most of what they do isn't technology.
But it's generally a bad idea to critique any of that. Gets one nothing but hatred. <- I explicitly wrote my comment to be friendly, fact-based, and make my thesis as clear as possible. If you're going around pointing out that "medical basics that we've known for a while matter", nobody is going to agree with you. But if you attack doctors/medical researchers the way you do, you instance cause people to interpret you as somebody to argue with.
