IMHO you're doing it a disservice by calling it a "narrative" and comparing to christian cosmology. On the face of it I think ideas like "past some threshold AI can become dangerous to humans" or "AI can become more intelligent through a positive feedback loop", even if speculative, have some plausibility and are worth investigating. You are basically chiding people for changing their mind in the face of new information, while still staying committed to some core ideas based on argumentation which is not challenged by this new information. Sure, this roughly looks like what happened to religions as science developed, but it looks just as much like how any scientific or philosophical field of inquiry makes progress.
