Building on that, how long did the AI take to draft the 77 news articles? Now ask a human to draft 77 articles in that same amount of time and see how many errors there are...
We are already awash in more articles and information than ever, and how long it takes to produce them isn't very important outside of a "quantity over quality" business model.
For this to be meaningful at all would have to presume that if the AI is faster, that making it take longer would improve its accuracy, which is almost certainly not the case.
It would however allow more accurate but slower humans to check its results for errors.
I find plausible that, in the near future, AI will be capable of generating content at a pace so high that we won't have time and resources to guarantee content accuracy and will very soon surrender to accepting blindly everything it spits out as truth. That day, anyone pulling the strings behind the AI will essentially have the perfect weapon at their disposal.
