Haha, asking chat-gpt surely won't work. Everything can "feel" like a halting problem if you want perfect results with zero error with uncertain and ambiguous new data adding.

My take - Hallucinations can never be made to perfect zero but they can be reduced to a point where these systems in 99.99% will be hallucinating less than humans and more often than not their divergences will turn out to be creative thought experiments (which I term as healthy imagination). If it hallucinates less than a top human do - I say we win :)
