> So much of medicine and treatment is literally just hearsay and whatever your surgeon happened to read last week. I think that you can replace "medicine" with "technology" and "surgeon" with "programmer". Something that I don't know about medicine into highly advanced countries: How do surgeons learn about the latest techniques? I assume they subscribe to some key industry/professional journals and/or go to annual conferences to discuss specific techniques. I know that dentists do it because I have asked multiple dentists about it. (In my life, the type of doctor that I visit the most often is a dentist for twice-annual checkups, so I see regular improvements to care and treatment.) Finally, I doubt that most surgeons would agree with your statement.
