Our language is evolving into all just letters short for words, and new "trendy" words descriptive of something we already have a word for. I fucking hate it

I just hate how generally gen Z (since my birth year is one of the youngest of the millenials) and whatever sub-generation below gen Z are fucking ruining the language. I say this because as far as I can remember, when I was young the only shortened words were "lol", which is originated to before my birth. And other people my age today, write full words and sentences to each other. So the "kids" born from 2002 and later is the ones to blame. How fucking lazy can you be, when the new normal is writing shit like "wdym", "smh", "ttym" etc. - basically a whole sentence (or multiple words) shortened down to 1-4 single letters? It gives me cancer to read. Same applies to e.g conversation shorten to convo, why? It would have taken 0,3 sec to complete the word to conversation. And if you add "y", by mistake you have a word meaning ships. And sometimes I even hear people say "we need to have that convo", verbally in public.

And I haven't googled this yet, but it's an educated guess the origin of the word, is as of late, gaslight (gaslit) since the word manipulative means the exact same thing. Why??

Also ignoring adding commas at all, which fucks up the meaning is becoming a big problem, when you read posts online. E.g. "I'm eating grandpa" & "I'm eating, grandpa". Last of this rant: you teens and early 20s writing like you are 10 years old, aren't gonna do you any favours when you are beginning in your first "grown up job". Getting the habit of being so lazy that you, in the future, need to use chatgpt to reply to an email where you're invited to an interview for a job opening is just tragic.
