My answer to your assertions is yes and no. Majoring in Math/Computer Science will definitely be an asset if you want to create the next Matlab or Mathematica. However, if your goal is write the ultimate "For Dummies" book, your technical background will probably work against you if you are unable to dumb yourself down, so to speak. Having majored in both Mathematics and Computer Science, I can honestly say it has been invaluable for my career and I my current entrepreneur endeavors. The most important thing that you'll have to learn is, if you want to be successful, you'll have understand those around you. Having a Math/CS education is not the issue. Not having the personal skills to recognize deficiencies in yourself and others is what is going to hurt you.
