I've been seeing this a lot lately. Everywhere from screen printed signs to news tickers. I'm not sure if this is because it's new or if I'm just now seeing it.
Yeah, call me snobby or OCD but I lost confidence in the authors and reviewers when I saw that slipped through.
Then I started wondering if this is going to become the new anti-AI marker. AI-written papers use "delves", "underscores" and "showcasing" too much. Avoid those words, throw in some errors and readers will think your paper was written by humans.
Their probably just unaware of the affect they're words wood have on us. Its no big deal and we should just except it. I wouldn't altar a single word. They've been served there just deserts, and I would of maid the same mistake. Let sleeping dogs lay. They probably never past English class anyway, and your far two picky about these things.
