* 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.
I think we are in a MAD crisis, as the motivation to continue unsatisfactory control over development of AI is from unlimited capital inflow.
Human history is full of examples of this stuff plateauing and hitting hard scaling walls. Not only technology wise but economics and useful applications.
So much of this tension with AI is because everyone's concept of AI comes from movies and books, and nerds drinking Kool aid (see also: web 2.0).
