Isn't that almost always the case, and in truth the beauty of automation? Replacing simple, repetitive tasks that, if you have to do that, you say "I wish I had a machine doing this for me"?
Of course, that might impact the number of available jobs and it's something that need to be taken under control.
But, if talking about writers, while AI won't realistically replace imaginative authors and investigative journalists (at least, certainly not in the short term), it will likely replace (some) copy editors and dollar-per-thousand-words "journalists" that have to fill tabloids and free subway "newspapers". While it might be a financial loss for the people involved, the society will hardly sink due to that. In fact, if I feel optimist, in theory it might reduce costs for publishing houses and newspapers, to invest more into quality (human-made) content.
