Most news articles don’t seem to be even proofread anymore! At least AI spells perfectly. It will at least likely soon replace the uncreative who/what/where/when news writing.
But if you write such an article, you need to convery specific information - about the "who/what/where/when" of the news story. This is information that was not available to GPT-3 at the time of training (e.g. it doesn't know that Biden is the PotUS now) so someone will have to sit down and craft a prompt that contains this information and such that it causes GPT-3 to generate a piece that repeats this information. To do all that sounds like a lot more work than just writing the article by hand.
