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.

Destroying confidence in the electoral system and other pillars of democracy (media, courts) is their goal, it’s not just pathetic whining. Then they use that lack of confidence to push strongman powers, restrictive voter suppression laws, and other crackdowns.
We are ten years into allegations of widespread election fraud - only for elections Trump or republicans lose, mind you - for which Trump and allies have either not produced evidence, or claimed evidence which was subsequently debunked. And blatant contradictions - such as celebrating wins under the same laws and practices while confidently declaring theft for any losses - are now the norm.

When fact-checked to his face, Trump defaults to insults and smears: "You're either crooked or you're stupid." "Your elections are crooked and you're crooked, and Meet the Press is crooked. And so is ABC and CBS and CNN," Trump said.

"Do you have evidence?" "That's not evidence." "There is no evidence." @kwelkernbc kept rebutting Trump's lies about January 6 and about election fraud, and he eventually wrapped up the interview, calling her "crooked." Here's the transcript of the astonishing final few minutes: WELKER: Do you think anyone who attacked police officers on January 6th should get taxpayer money? TRUMP: I wouldn't be inclined to say so, but I have to see it. I can tell you this: 97% of those people, you look at them, the FBI or whoever it was, cause you had a lot of crooked cops, you had dirty cops. Comey was a dirty cop. WELKER: Well, there is no evidence to – TRUMP: A guy like Bolton was a dirty cop – WELKER: But there is no evidence that-- but there's no evidence that people who – TRUMP: Wait a minute, wait a minute. Oh, you think Comey was a straight cop? WELKER: We had 170 people who pleaded guilty to assaulting police officers. TRUMP: Comey was a dirty cop. WELKER: No, no, but the people who assaulted police officers. TRUMP: They had FBI – listen to me. They had FBI agents ushering them into the building. They had FBI "Go into the building." Those people are walking around, they're looking, "Oh, isn't this nice?" They weren't in-- they were being ushered into the building. WELKER: There's no evidence of that, sir. There's no evidence of that. TRUMP: You had a bunch of dirty cops, and frankly, what they did was weaponization of our government. WELKER: But sir, there-- there's no evidence of that. More than a thousand people pleaded guilty to crimes – TRUMP: No, well, yeah, no, there's none. You know what they do? WELKER: Would you – TRUMP: Try looking at the tapes one time. WELKER: Would you take it off the table? TRUMP: Look at the tapes one time. WELKER: Okay, but 172 people did plead guilty to assaulting police officers. TRUMP: You know why they pled guilty? WELKER: Should they be exempt – TRUMP: Because they told they were going to jail for 15 years – WELKER: – from receiving funds? TRUMP: – if they didn't. WELKER: Should they – TRUMP: They pled guilty because they were frightened. They went down. They were ushered into a building. Many of them were arrested without even going into the building. WELKER: You'd be okay with them receiving taxpayer dollars? TRUMP: The people were destroyed by dirty cops and by weaponization. Many of those people should be compensated. Now, with that being said, the, as I understand it, the weaponization fund was going to set up a group of people, people that could be picked by anybody, fair people, smart people, and they will go on an individual case basis. WELKER: Okay. TRUMP: Now, I don't know what's going to happen with the weaponization fund. I love the idea, because people like you, the fake dirty press, the crooked press, people like stupid Biden, he's not smart enough to know what's going on, but people that surrounded him, surrounded his beautiful Resolute Desk in the Oval Office, what they did to the lives of people, they destroyed people. They sent people to jail who did nothing wrong. WELKER: All right, this is, just to be very clear, there's no evidence of what you're saying, but let me ask about Todd Blanche. TRUMP: There's a lot of evidence. WELKER: Let me ask about Todd Blanche. TRUMP: Listen – listen to me – listen to me. WELKER: Let's talk about Todd Blanche. TRUMP: There's tremendous evidence. There's nothing but evidence. WELKER: Well, it’s not been presented in a court of a law. TRUMP: The election was rigged. It was a dirty election. WELKER: Mr. President – TRUMP: And it's happening again right now in California. WELKER:  – you've never presented evidence – TRUMP: It’s happening right now in California WELKER: – that the 2020 election was rigged. TRUMP: Right now, it's look at what's happening in California. WELKER: Where's the evidence to that? TRUMP: It's four days – WELKER: The Republicans are doing well in California. TRUMP: In California, it's, no they're not. They're dropping fast because it's a rigged election. Let me tell you, it's four days and they aren't even close to coming up with the – WELKER: That's how they count the votes in California. TRUMP: Do you know why they're doing that? Because they're cheating on the election. WELKER: There's – What? Do you have evidence to support that? TRUMP: It's-- all I have to do is look. All I have to do is look. WELKER: But that's not evidence. TRUMP: And I listen. And I listen to people. And let's see what happens. WELKER: But sir, that's not evidence, and that's how they count the votes in California-- TRUMP: Do you think it's appropriate that they have an election and five days later, they're nowhere close to picking a winner? WELKER: State and local officials acknowledge they are slow. They're urging– TRUMP: No, they're crooked. WELKER: – they're urging the votes to be counted quickly. That's how they vote in California. TRUMP: They're crooked just like you're crooked, your press is crooked. And Meet the Press is crooked. WELKER: To be fair, I'm not crooked. But let's continue. TRUMP: Really? Well, you play right into their hands then. WELKER: Let's continue. TRUMP: You're either crooked or you're stupid. WELKER: Let's continue. TRUMP: You play right into their hands with this stuff. You know that these elections are rigged. Your network knows that they're rigged. Do you know that I won an election in a landslide and I got 94% bad press. WELKER: But Mr. President – TRUMP: You know why I got that? WELKER: – you've never presented – TRUMP: Because you have no credibility. WELKER: -evidence. But you've never presented evidence it was rigged. Let's keep talking about, I want to talk about Todd Blanche. TRUMP: You have more evidence, there's more evidence than ever presented. WELKER: Let's talk about-- TRUMP: Your elections in this country – WELKER: – you went to court. TRUMP: We're like a third world country. WELKER: But sir – TRUMP: Your elections are crooked and you're crooked, and Meet the Press is crooked. WELKER: But Mr. President– TRUMP: And so is ABC and CBS and CNN. WELKER: But Mr. President-- TRUMP: You're a one-sided crooked network. Sorry. Let's call it quits because I've had enough. Thank you, darling. Have a good time. WELKER: Mr. President, let's – please, I traveled all the way to Wisconsin. TRUMP: I've sat in the rain with you-- WELKER: I traveled all –  I know. I traveled all the way-- TRUMP: I sat in the rain with you for an hour. WELKER: --to Wisconsin. TRUMP: On and off in the rain, and I've given you enough time. You ought to straighten out your press, because you know what? WELKER: Mr. President-- TRUMP: A country can never be great with a dishonest press. WELKER: – we traveled all – listen. We traveled all the way to Wisconsin for this interview.
