An excellent choice - you will come to appreciate how precarious the code that runs the algorithms truly is. You will then hopefully not rely on computer systems to fly you higher than a wheel's diameter!
I have a degree in computer science, yet I find the analogue represenattions in the cockpit and imagination stand me in better stead than mental maths. I am living proof of the downside of the Von Neumann model and the single thread.
You could always use your maths bent on an Economics and Philosophy course and answer the questions of how/why we fly and why it is so expensive...
I wish you the best of luck - just don't do meja studies!
