>but I don't assign cultural significance to them.

That's just what it feels like not to be important.

In older books that persisted over long periods of time and popularity we've seen misspellings of the same word on the same page. These things got copied selectively over time and caused splits in language.

In the modern age quite often these misspellings can evolve into new words and/or memes. It's how language evolves.

At the end of the day it's very difficult to do anything about this at scale without reversing a bunch of technology. Simply put the average person isn't this careful in day to day writing. Yet we ask the average person to create more writing per person than any other time in history. By anecdotal observation I believe that most of these people don't want to shit out zillions of lines of text at all and only feel forced to do this by modern demands. Hence, this is why LLMs quickly took over shitting out zillions of lines of text. The people that were doing it by keyboard before were glad to give it up. The number of people that want to be precise about it is simply very low the same as the rest of history.
