Part of it comes down to an effect that's been known for a long time with human-computer interaction.
Whenever you have a machine in the decision loop of a job, many workers WILL DEFER to the machine whenever there's a question of whether something is wrong or right.
By deferring to the machine, the workers absolve themselves of accountability and shift all responsibility to "the system". I think this is often deliberately "baked in" by management to customer service of all kinds. You can see this in a small way if you've ever had to call an internet service provider in the USA to deal with a billing mistake.
