alt Hacker NewsMy argument is more to the tune of "everybody’s code looking slightly different is not a problem in practice as long as I can read and understand it."
However since you've asked so nicely here you go: everybody’s code looking different is because all humans are different. It's what makes us human. I am very serious about my craftsmanship, and I bring my "humanity" to it: sometimes I include a cultural reference (as in the example above), or an internal joke in the name of a (very long) variable, or vent my frustration in a comment.
My first ten years of writing Python were uneventful; nobody commented about my style and I never commented about others'. With the advent of grammar nazi bots, everyone is supposed to now please them by writing completely bland code, which in my opinion degrades me from a craftsman to a code-monkey. This is dehumanising, in a certain sense.

I'd go so far as to argue that person to person differences are helpful to a reader. When I am dealing with a long term code base it's easy to develop a feel for who is responsible for different constructs without needing to rely on the git history. This gives me immediate information on what to expect.
But your choice of funny variable names is not a craft, and you’re not a craftsman if you think it matters. What matters is extensibility, maintainability and value delivered.
I care how the food tastes, not that the chef has a really cool Japanese knife and is really fast at cutting onions.
