Hey thanks for reading the article. So, it's more to do with social media, but the same trend would be followed with all the LLMs being around.

I'm from northern part of India, where we speak Hindi, since the advent of social media, I've personally seen that people can't speak and write properly, in either Hindi or English, They write a completely broken language with a lot of short forms and just keep mixing the words from both the languages.

I have actually read letters from world war 2, young boys barely 16-18 wrote much better than what I see in the things posted by people, even with advanced degrees.

And if you want to see the numbers, read Johnathan Haidt's work, all the basic indicators have gone down a lot. To the point where a significant minority of graduate level students couldn't do basic Maths and comprehension, things they should be able to do in class 10.
