Don't agree with this.

LLM when it came out, was perfect as an interface between a system and a normal human.

So many people call customer support for issues they could in theory fix themselves. If that LLM system can understand me well enough, its an okay interface.

In worst case you have to escalate anyway. My mum actually told me that she talked to some AI.

And yes normal systems are also not correct often enough. With AI/LLM software will get cheaper which should incresase quality overall.

I dont think ai/llm in this case will change anything.

Relevant change will happen due to the fact that humans can be replaced by AI/LLMs. It was not even imaginable a few years back how a good ai system would even look like. Translaters lost their jobs, basic arists lost their jobs. Small contracts for basic things are gone. The restaurant poster no one cares? AI. The website translation for some small business? no one cares.
