Ars is owned by Conde Nast, which is owned by Advance Publications. Ars's parents could have funded all these to ensure journalistic integrity, but would rather squeeze their staff and make money off the brand goodwill and advertising.
Should fact checkers have fact checkers to check the the first batch wasn't incompetent and didn't use AI to rewrite the article to add more "facts"?
