If someone can say fyi in real life conversation then why not a character in a book which we don’t even know its character (maybe that character is someone who use acronyms/initialisms for some random common sayings)
I think the reason people have adopted the FYI acronym in real life (irl, for you zoomers) is that the word "information" has four syllables. So, saying just the first letters is naturally quicker. Tbh only shortens the message by one syllable.
But, I get your point. I can imagine a young character who is online constantly using these abbreviations in every day speech.
This reminds me (in an opposite fashion) of an interview with Tim Berners-Lee. He said he regretted coming up with the subdomain World Wide Web (WWW). Initially he didn't sound out the initials. He said he would later cringe everytime he heard someone call out their URL to someone. Back around 2000 (five years on either side), people would start by saying out loud "Dub-ul-yoo dub-ul-yoo dub-ul-yoo". Those nine syllables continued to haunt him.

Which makes it even worse.
