Many people in our profession write code that's less that 80 characters per line because that's how much you could display on terminals in the 70s.
As a profession, we can't complain that someone might be bothered by the idea of word-wrapping.

It's _also_ a very reasonable & readable amount of text in a row. There's nothing wrong with that.
Presumably, that's why they used 80 characters in the first place, as anything more is too hard to read.
80 column displays date back to the early 1970s.
I started coding on an 80 column display, and I have no doubt at all that a modern 16:9 monitor that can display a double page PDF or a web page with a variety of fonts is a much better display device.
To be fair, 120char wide code is also not too bad for this purpose and readability.
It also helps to keep my code readable; the shorter the line, the quicker I can work out what exactly that line happens to do. In the vast majority of cases, an inability to keep a line within 72 characters is a line that needs refactored.
