This is a good analogy, but you made it backwards. The "Clergy" fears the "Printing Press", as it acts as a tool of decentralized information spreading. But LLMs are not decentralized and thus are not the "Printing Press". LLMs are what the "Clergy" (say, for example, all the AI companies led by billionaires in cahoots with the west's most powerful government) uses to suppress the real "Printing Press" (the decentralized, open internet, where everybody can host and be reached).
