There is a fundamental difference between math and code. In a typical modern day computer instructions, and the data to be manipulated are put in the same place [1]. This is a critical feature that makes things like downloading a program and running it possible. But for programmers to keep their code "safe" they must enforce artificial boundaries between the instructions (code) and the data. Hackers are experts at crossing those boundaries and tricking computers to treat data as code when they shouldn't.

Mathematicians have the good sense to keep their data and instructions separate. [2]
