Not sure about "no longer worrying about that pesky 80 column limit"...

For once, I have an ultra wide monitor, and having 1-2 files of code, a terminal and a space for testing and research all next to each other is quite great.

Furthermore, I'm probably getting too old, but I find line length limits really helpful for readability: When you start to wrap those long lines, it kinda makes you think about introducing some temporary constants, extracting logic into a separate function, Not nesting conditions and loops too deeply... Maybe I'm just so very used to it, but I'm a fan, regardless of monitor size.
