The line "a 'Butlerian Jihad Against AI,' a reference to the Legends of Dune prequel trilogy" appears in the original article, so the journalist who wrote it seems not to have known what it was and searched online for it. www.wweek.com/news/2025/08...
The Butlerian Jihad is entirely explained in Herbert's original books. Ironically if you 'let a machine think for you' and do an online search for "Butlerian Jihad" the algorithms of the search engines give you one of the prequel books as a top result. Fitting!
