The author completely misses or ignores the volume of research on line length and readability[1]. "I cannot find a single logical reason for why we would actually need character line limits when writing code - at least when we assume that part of the developer’s job is to structure and format their code in a readable way."

How about this one: if a developer chooses a smaller line width for readability reasons, depending on the editor to wrap code is a fail. The chance the editor wraps the line at a semantically sensible point approaches nil. Perhaps there's a place for better code editors that wrap according to semantics, but for now, editors don't take it into account.

Betteridge's Law applies.
