My good sir, I regret to inform you that the informality of the English language has been in decline for quite some time. Possibly since that vulgar bard Shakespeare abandoned all pretense of a shared language and raised a generation that thinks words like "fashionable"[sic!!] are real words.
However, it is notable that the rules of this particular venue request one be charitable to your fellow forum goers, and thus the admonition that their preferred communication is "slop" is generally considered unwelcome.
Would that you had only been able to word your own communication is in proper vocabulary and grammar; alas, I must conclude that even as you reject modernity, you have embraced the "slop" of the past.
But to address your last sentence: OP explicitly admits to using AI in the Reddit comments, and apologizes for it. https://www.reddit.com/r/ClaudeAI/comments/1wzw8zd/i_think_i.... If you are going to repeat this libel, at least have the decency to provide some sort of citation
is this supposed to be an example of bad writing because unnecessary bombast is definitely a sign of it
good writing is not just replacing random words with entries from thesaurus.com, it's writing for your reader. that's one thing LLM-generated text is very bad at - frequently violates the show-don't-tell rule, it lacks any interiority by it's very nature, etc
if you don't practice writing yourself, you don't develop the muscle of knowing what your reader's expectations are and you will forever remain a mediocre writer
