Is there something to the story that I'm missing? Why does Orland need to apologize? Edwards fabricated the quotes via AI and seemingly presented them to Orland as authentic. Orland had no reason to suspect the quotes weren't real until after publishing.

When journalists are working on a shared byline, they don't each do the same research in order to fact-check each other. There is inherently a level of trust required for collaborating like this and Edwards violated that trust.

You can say this is a failure by the editorial process for not including fact checking, but that is an organizational issue with Ars, it's not the fault of Orland for failing to duplicate the work that he believed his coauthor did.
