You have a valid point. I felt that my love for math and algorithmic thinking (although not part of a formal curriculum) have been very helpful. Medicine is more like engineering than most people think. Keep in mind though that everything looks like a nail to a hammer. The same way they lacked in some way, you lack too. Unless you expand your knowledge base in the end you will be limited in analyzing similarly generated data with slightly better ways, as is so often seen in the literature. At the same time researchers who possess the knowledge to work "under the hood" are designing novel ways to obtain data, ask new questions and design the accompanying pipelines in the process. Where you put mathematics major feel free to insert molecular biologist/ nuclear physicist/ organic chemist/ or whatever else you like. I feel that if you really want to be spectacular and at the interface of many sciences you have to master one and have a good understanding of the others. And as a doctor you will always have it easier to lead a team for human disease research, the prestige of the degree by itself and the fact that you have actually seen what is being studied will always give you some respect if you are not a complete jerk. The bar can only be set higher and higher...
