I don't know, even ChatGPT 5.1 hallucinates API's that don't exist, though it's a step forward in that it also hallucinates the non existence of APIs that exist.

But I reckon that every time that humans have been able to improve their information processing in any way, the world has changed. Even if all we get is to have an LLM be right more times than it is wrong, the world will change again.
