Journalism is not only about writing. It is about sources, talking to people, being on the ground, connecting dots, asking the right questions. Journalists can certainly benefit from AI and good journalists will have jobs for a long time still.
While the above is true, I'd say the majority of what passes as journalism these days has none of the above and the writing is below what an AI writer could produce :(
It's actually surprising how many articles on 'respected' news websites have typos. You'd think there would be automated spellcheckers and at least one 'peer review' (probably too much to ask an actual editor to review the article these days...).
Mainstream news today is written for an 8th grade reading ability. Many adults would lose interest otherwise, and the generation that grew up reading little more than social media posts will be even worse.
AI can handle that sort of writing just fine, readers won't care about the formulaic writing style.
So AI could actually turn journalism more into what it originally was: reporting what is going on, rather than reading and rewriting information from other sources. Interesting possibility.
