I'm more concerned about the consequences of applications that are either poorly understood, or applied with malice (ie by people who don't care if it's biased)
The effects would be more insidious, so it could do more harm before the world cares, and there's more opportunity to just go "oh it's computer magic. But trust us, it's specially programmed to always be right so really it's better at making these judgements" than something more overt like a Hollywood style robot rampage.
