In the "our biggest danger is a daily danger" camp, I prefer analogies like:

* Asbestos: AI models making business-decisions which cause a ton of unrecognized damage, which cannot be healed, and replacing them with reliable processes involves expensive re-architecting.

* Radium Toothpaste: AI assistants that end up dealing psychological damage, especially if they are pitched as your friend or confidante.

* Chemical spills and plant accidents: Oops, our server-banks were manufacturing our latest desperate attempt to Create Digital God and in the process we accidentally destroyed/crippled/compromises some people's sites and databases because we weren't really paying attention to what was going on.
