It is far more likely that AI-written articles will become harder to spot, not that they will stop being written.
Calling what out? Did we suddenly invent a durable Turing test that will last more than six months? (We didn't, but some people "just know")
The only durable metric is if the article is good, if the ideas are good. Everything else is complaining about Bob Dylan's electric guitar.
I posted this elsewhere, but convincingly, consistently "writing like AI" and never slipping once takes an amount of knowledge and skill analogous to art forgery. Except that with art forgery you can at least make millions of dollars off it.
If you want to read chatbot output, why are you coming here? There's a ton of free chatbots for you to read.
After all, the audience here knows where to go to get chatbot output, but they're coming here instead. What does that tell you?
That HN was a neat community fifteen years ago, but like all things cool made by early adopters, it will eventually attract a following hoping to be somewhere, to exist among people doing things, but the tragedy of such followings is that they bring with them their toxicity, their immunity to their own poison, and drown out what they depend on until the early adopters early adopt away.
The real slop is all this lazy concern farming from an ant mill that is powerless to do anything except validate its own hand wringing.
Which circles back to the question of why, if you want to read AI output, are you still here?
You can read that sort of thing just about anywhere else.
