You have noticed it. ChatGPT feels dumber than it used to. Your prompts that worked six months ago produce worse results now. The writing sounds flatter. The ideas sound safer. The internet itself feels like it is shrinking. Every article reads the same. Every email sounds the same. Every answer sounds like it was written by the same voice.
You thought it was you. It is not you.
Researchers at Oxford and Cambridge published a paper in Nature proving what is happening. They call it Model Collapse.
Here is the mechanism in one sentence. AI trained on AI-generated data gets dumber every generation until it forgets what real human data looked like.
The internet is filling with AI-generated content. Blog posts. Articles. Reviews. Comments. Social media. AI companies scrape the internet to train the next generation of models. Which means the next generation of AI is being trained on the output of the current generation.
Each cycle loses information. Not randomly. It loses the rarest, most unusual, most creative parts first. The researchers call these the "tails of the distribution." The weird ideas. The unexpected perspectives. The things that made the internet feel human. Those disappear first.
What remains is the average. The safe. The expected. The bland.
Then the next generation trains on that. And loses more. And the next generation trains on that. And loses more. The researchers proved this is not a slow decline. Major degradation happens within just a few iterations. Even when some of the original human data is preserved.
They tested it on large language models. On image generators. On statistical models. The pattern was the same every time. The output converges toward a narrow, flattened version of reality that looks nothing like the original data.
The lead researcher put it plainly. "Large language models are like fire. A useful tool. But one that pollutes the environment."
The pollution is invisible. You cannot see which sentence on the internet was written by a human and which was written by AI. Neither can the AI that is about to train on it. And once the tails are gone, they do not come back. The damage is irreversible.
This is not a prediction anymore. It is a diagnosis.
The internet you grew up on was built by humans writing things no algorithm would have written. Strange, personal, imperfect, alive. That internet is being diluted. One generation of AI at a time. And the models trained on what remains are learning a smaller and smaller version of the world.
Model Collapse is not a technical problem. It is a cultural one. The thing that made the internet worth reading is the thing that disappears first.

Os negros de lá são literalmente escravos modernos, já que a 13ª emenda (que proibiu a escravidão) autoriza trabalho não remunerado em caso de prisão. Uma parte considerável das prisões é privada e adivinha quem vai preso.

An Iranian man left this comment on my YouTube channel. This is without a doubt the single best explanation of the reality facing Iranian people today👇
"As an Iranian, I can tell you the situation is no longer just political—it's existential. We are trapped between two collapsing structures: one internal, one external. On one hand, we face a deeply dysfunctional government, led by the Supreme Leader and the Islamic Republic’s unelected institutions.
Decades of economic mismanagement, suppression of dissent, and brutal ideological control have alienated multiple generations. No one believes in reform anymore—because every attempt has either been co-opted or crushed. But here's the paradox: We are also terrified of regime collapse—because we've watched the aftermath of Western intervention in countries like Iraq, Libya, Syria, and Afghanistan. Each was promised freedom; each descended into chaos, civil war, or foreign occupation.
So no, we don't trust the U.S. or Israel. Not because we support our regime—but because we know how imperial powers treat ‘liberated’ nations in the Middle East.
Freedom, in their language, often means vacuum, fire, and permanent instability. Right now, many Iranians live with three truths at once: The Islamic Republic is morally and politically bankrupt. The alternatives offered by foreign actors are not liberation—they’re collapse.
A bad government is survivable. No government is not. We are not silent because we agree. We are cautious because we’ve learned—too well—what happens when superpowers decide to "help." In a sentence: Iran is a nation held hostage by its own regime, but haunted by the fate of its neighbors. We are stuck in a house we hate, surrounded by fires we fear more."
