The problem is that Math PhDs tend to be arrogant and think that programming is for monkeys and they are above that. Code that they produce tends to be sub-par and under-tested (because they are above writing unit-tests). Source: worked with multiple Math PhDs. Have a few friends who are Math PhD working on some esoteric problems that I could not understand.
