The journal in which it appeared is a predatory journal with a good PR department. I hope this is the last nail in their coffin. If you see something published in a "Frontiers In" it's most likely rubbish. Only god knows what kind of peer review the article went through (if any), in the most optimistic case it was reviewed indeed by peers of the people who submitted an obvious AI generated article, probably they sre already thinking of submitting their own.
