It could have been a story or something that I read in an article, but the point remains. We shouldn't blindly trust results/calculations if we don't have a feeling of the correctness or how the result is derived. I understand that this isn't valid for many cases where difficult and complex computations are performed, but for many real life scenarios and situations it's valid. As stated in the original article, the people holding the AI strings are somewhat disconnected from us real people and they lack this human and real life touch. I hope I've explained it correctly :-)
