Oh this hadn't occurred to me. Yikes. Another reason to throw AI into the Sun.
I am by no means a prominent public intellectual, but my inbox is increasingly filled with messages from people who have been convinced by sycophantic chatbots that they have discovered revolutionary theories that entirely upend our scientific understanding of the universe.

This is an incredibly difficult but incredibly important article by Rebecca, involving Epstein, Lawrence Krauss, and others. I ocassionally get asked why I don't do skeptic events anymore, and if you read this you'll get a pretty good idea of one big reason why.
Mainstream news covered the Jeffrey Epstein emails related to ppl like Trump. Today, I want to take a look at Epstein's correspondence with prominent atheist and physicist Lawrence Krauss, who asked the pedophile's advice on responding to accusations of sexual assault skepchick.org/2025/11/so-i...
So I’m in the Epstein Files
Transcript: Look. I know that on this channel, I often criticize prominent people for actions that I find detestable: accepting dark money and failing to disclose it, producing propaganda for Big O…

Its very very bad that the President publicly posts a statement that, were I to post the same thing about him, would have the FBI knocking on my door.

A reminder that inside that soft, spongey skull is a big scoop of cottage cheese and hatred and nothing else.
Trump on AI: "You can't go through 50 states. You have to get one approval. 50 is a disaster. Because you'll have one woke state and you'll have to do all woke. You'll be back in the woke business. We don't have woke anymore in this country. It's virtually illegal. You'll have a couple of wokesters"

This is wonderful, and shows where curiosity can take you and others (including professionals!) even if you're 8 years old. It helps too that the Astronomer Royal is aces.
Enquiry from an 8yo asking what the Fulton Orrery planets were? Apparently the #Kelvingrove museum staff didn't know, so he e-mailed the Astronomer Royal to find out! I also didn’t know, but the AstroSociety of #Glasgow did (after watching an old VHS recording on the topic!) 🔭 #histsci 1/2🧵

It's been bugging me too. I think it's because it's more personal, more slimy and gross than his usual evil bigger stuff.
Because it should have provoke a reaction from her peers and colleagues and in general adults in the room and it didn't because its grandpa Trump, and that's morally and ethically wrong, and staring at it and sitting in it doesn't help any of that
I don't know why the "Piggy" thing is bothering me so much. It's one more unforgivable thing in a list of 20,000 unforgivable things, but I've been mad about it for like 12 straight hours.

This is what happens when science gives you very clear warnings but you stick your fingers in your ears and go "LALALALA".

A reminder that seven years ago almost to the day, the CIA determined that Mohammed Bin Salman ordered the killing of @washingtonpost.com journalist Jamal Khashoggi.

I hired and worked with Jamal for a year.
