AI had led to significant operational improvements. The speed of root causing has increased by multiple times and the time spent head-desking or chasing leads have reduced significantly - even if the AI is wrong the first few times, it is recognizable that it would sometime be a rabbithole that I myself were likely to spend time - a lot longer time in.

It obviously cannot do these things by itself because it can arrive at the wrong conclusion all the time and be pretty stubborn about it, but at the same time to say there are no benefit is like throwing a bike away because you fell riding it the first time and go back to walking.
