Maybe I'm just weird, but I believe that readable code is a prerequisite for correctness and security. Some people would argue that readable code is not needed for correctness and security if you have good test coverage. But I'd argue that because the tests are also written by humans, how do you know you are testing the right things, and testing correctly, if your test code isn't readable? Ultimately, that judgement has to come from humans reading the test code and the program code.
