Writing proficiently is dropping with LLMs in school, 
    and reading proficiency is worse than the early 2000s. 
    But i don't think this tells the whole story either.

It's very easy, but also lazy and simplistic, to look at the decline of writing proficiency and equate it with some kind of 1:1 decline in overall interpersonal communication.

People certainly struggle with communication in 2025. It's hard.

But if we are to believe that communication has somehow declined over time, then we must also accept that communication was somehow in some kind of amazing or at least superior state 100 or 200 or 1000 years ago. I see no evidence that is the case. The most casual look at history or classical literature shows those times were chock full of miscommunication foibles, both trivial and world-changing.
