The idea that theory does not match practice is very foreign to a software developer or somebody that works in the information processing field. We are spoiled to have mathematicians do the hard work, and then we just get to botch it all with software that doesn't even work. But people with real jobs doing actual science/engineering know that the practice never matches the theory and that one needs to harden their balls in the thick of battle to come to a true understanding of things. That's why only a software developer, in their full command of hubris and ignorance, would suggest that you can replace a doctor with a computer program that has digested every book in existence and then statistically regurgitates its contents.
