IMO, the labor saving part of journalism is in filling in background fluff and other side info. If a journalist is writing a story and needs a half page background info about a subject, an AI can throw that together and let the journalist write the key paragraphs of actual information. All that is needed is to do some editing of the AI written part. If the entire article can be written by the AI, then it wasn't much of an article to begin with. From what I have heard, the AI just combines info from multiple sources.
I think everyone is going to have to consider what value their work is actually providing. Hourly workers have already been through this and likely will in the future. Corporate office people will now go through it as well.
