Errors can give away that a human typed something, but knowing proper grammar, spelling, and syntax of English is totally neutral—if not to be somewhat expected from a native speaker/typer with a lifetime to learn the language they speak (especially if we consider how many Anglophones are monolingual + educated + have access to technology like spell check meaning there is little excuse for not having English mastery).
In my education, I got a public apology from a teacher letting the class know they tried to dig up proof of plagiarism in my persuasive papers, but for the first time proved themself incorrect on a plagiarism hunch. Humans are capable of writing well.

Think of the phrase: about music. “90’s music” would imply music from specifically 90 (probably 1990 where we assume the writer was lazy about the initial apostrophe)—possessive form. “’90s music” uses ’90s as an adjective for the entire decade—and with the preceeding apostrophe makes it clearer 19 is omitted. 1 year versus 10 years as a big difference. Using an apostrophe in the right place clearly removes the ambiguity.

One man’s pedentry is another man’s pet peeve. This is a syntactic error that isn’t just a typo but a misunderstanding of the mechanics of apostrophes.
