have worked closely with customer support teams, can confirm that the goal of any technical improvements that go in front of CS agents is to reduce ticket volume, and thus costs. of course they measure retention and satisfaction but ticket volume is always the big one. chatbots were big for this long before LLMs existed.

a fun side effect is that CS is also an early warning system for companies, so when you make it harder to get through to a human, you start throwing out info on your users' pain points. of course this only matters if people have a choice about whether to use your product, so that's gotta be an upside for insurance companies, etc.
