>in the context of call centers in particular I actually can believe that a moderately inaccurate AI model could be better on average than harried humans

You're free to believe that of course, but you're assuming the point that has to be proven. Not all fuck ups are equal. Missing information is one thing, but writing literally opposite of what is said is way higher on the fuck up list. A human agent would be achieving an impressive level of incompetence if they kept on repeating such a mistake, and would definately have been jettisoned from the task after at most three strikes (assuming someone notices). But firing a specific AI agent that repeats such mistakes is out of the question for some reason.

Feel free to expand on why no amount of mistakes in AI summaries will outweigh the benefits in call centers.
