When we write code, it's essential to consider how human brains will consume it. Fellow programmers will scan over your code, reading the pertinent parts, attempting to gain a running comprehension of its inner workings. Readability is the first hurdle that they must overcome. If they are unable to read and cognitively navigate the code you've written then they'll be less able to use it. This will drastically limit the utility and value of your code.
