I guess the point is that they're largely technicians drawing from "the literature" (doctoring books, research, as well as user manuals for drugs and instruments). With a ~first year grad school level of understanding bio/chem pretty much anyone can be a competent technician in 90 percent of cases, and literally anyone can implement a cure so long as they can read the instruction manual (and it isn't tricky surgery).
