Where should AI draw the line in handling real-time human conversations?

I’ve been thinking about how AI is increasingly being used in real-time communication scenarios, customer, messaging, service interactions, and similar use cases. Technically, current systems are already capable of handling a large portion of repetitive conversations with decent accuracy and speed. In many cases, they respond faster and consistently than humans. But what stands out to me is that the real challenge isn’t capability anymore, it’s judgment. There seems to be a tipping point where automation goes from being genuinely helpful to subtly degrading the experience.
