I've yet to see any news outlets deal well with any of the times they have stumbled on stories in my spheres. The more context you need to understand the importance of the problem being reported on, the worse the articles will be from career journalists. The only good articles were about a workplace drug scandal; that was very fun to watch unfold from inside and outside. Career journos have nailed writing for that topic.
Having said that, I think current events reporting will suffer the most for this development though, because they rely on mostly new information that doesn't have consensus yet. It will be very easy for ChatGPT to replace a number in a tragedy with information from a previous similar incident or a wildly bad source. Oops, that protest now only had 20,000 attendees instead of 200,000!
