AI labs are working on and largely already have generative ai that can be actively updated. The generative ai scoops real journalists stories by watching their feed. This isn’t very different from the current status quo, it’s just a continuation of an already shitty situation for news organizations. If their revenue decreases even more than it already has they will cease to exist. Niche journalism barely has any demand today, it won’t take much more reduction in demand for it to not be worth the cost to produce. Just a few more people using big tech products as their news feed instead of the news organizations themselves is all it would take.
You can say that the people getting their news from the tech products will switch to paying news organizations in some way if the news starts to disappear but I highly doubt it seeing how people treat news today. And if it that does happen they’ll switch back again to the ai products as the centralization it can provide is valuable.
