I don't understand why more people don't realize this. I feel like a lot of people would consider a biology major who hasn't been in school for 20 years more of an expert on this sort of thing than Bill Gates, all because the student has a piece of paper saying they took like 12 classes loosely related to the subject. It's like the people who argue that "Elon Musk is a rocket engineer in title only" because he went to school in physics rather than engineering. Like, you don't think being the CEO and lead engineer of SpaceX for almost 20 years is a better education than a 4 - 8 year degree?
