>Programming is not a write-only operation

A lot of people would take issue with that statement.

Most devs probably wouldn't notice that their backspace key went missing until they were fine tuning the phrasing of an email about why the best way to solve their spaghetti is to make the same spaghetti slingers port the codebase to $FAD_OF_THE_WEEK.

Edit: It should be obvious that this is a joke but if it's not you should probably check if your backspace key still works.
