LLMs don't do what the film shows. (Nothing ever does what films show, unless it's a documentary, and even then sometimes not).

AI includes Google search results being re-weighted based on what people click on, the live bidding on which advert to show you when you visit a website, your facebook feed, and your spam filter.

All of these have been designed to earn your trust, they don't need to have an internal motivation for that. Some have been trusted, some are still trusted.

All may change on a dime and without warning due to some software update outside of your control.
