Incoming miracle: We are about to have mRNA cancer vaccines. No thanks to those have demonized this technology and tried to smother it.
We are talking more about how parenting became unaffordable. But I have also wondered: Why do we tend to think that other people’s kids are other people’s problems? And how did that come to be? This piece tries to find an answer. nytimes.com/2026/06/08/mag…
"For half a century, American parents have tried to be exceptional individuals, contorting themselves into every possible shape to make the raising of children possible. They have saved, they have delayed, they have settled for smaller families in smaller homes. They have tried to survive under the strangest logic that the act of caring for others, of all things, should be seen as an individual pursuit or even indulgence. The help that is needed never seems to come: There is no amount of private exertion that can overcome public indifference."
Women deserve to live in a world that prioritizes their health—full stop. That’s why I’m announcing additional funding for women's health, bringing my total investment over the past two years to more than $600 million. Here’s what that looks like:
If you want people to believe in the public sector, the public sector simply *cannot* be this wildly profligate with taxpayers’ money.
The role of the Governor is to protect Californians, and to stand between them and danger. That's a role I take very, very seriously, particularly when it comes to trans youth.
UnitedHealth is the nation’s largest health insurance conglomerate. ProPublica obtained what is effectively the company’s internal playbook for limiting and cutting therapy costs. Here’s what we found. propublica.org/article/united…
This announcement arrives hours after our investigation (newyorker.com/magazine/2026/…) described how OpenAI dissolved its superalignment and AGI-readiness teams and dropped safety from the list of its most significant activities on its IRS filings—and how, when we asked to speak with researchers, working on existential safety, a representative replied "What do you mean by 'existential safety'? That's not, like, a thing."

It’s actually a good thing that Americans are seeing high gas prices and long lines at airports. These are direct results of Republican policies More people need to feel the direct pain of Republican policies in their lives Politics is not some abstract concept. It is your grocery bill, your medical insurance costs, your ability to get childcare and hold companies accountable for fraud, and wealthy guys like me getting massive unnecessary tax cuts while you pay thousands more for a pointless war and tariffs
Millennials are the elite generation because they cranked out 12-page essays the night before they were due. No ChatGPT. No Claude. Just lo-fi beats playing in the background, Black coffee at midnight, footnotes that were somehow correct, and pure delusion. Grade was an A minus. Period.
Horrifying. We need to know exactly how this happened. Again, I do not believe for a second that this was intentional, but a terrible terrible mistake was made. We very much need to know if any policy changes contributed to it.
Breaking News: The U.S. was responsible for a missile strike on an Iranian school, an ongoing military investigation found. The inquiry said the strike — which Iranian officials said killed at least 175 people — was the result of a targeting mistake. nyti.ms/47G2uw2

.@OpenAI is nothing without its people -- many of whom are brilliant, ethical, and able to work anywhere. Please, guys -- is this empowerment of authoritarians really what you want to be striving towards? Your talents are better-used elsewhere.
It is incredibly depressing to see OpenAI employees trying to spin the OpenAI-DoW deal as a good thing. OpenAI caved to the Pentagon's demands. Your technology can now be used for authoritarian ends. Own up to it.
Dario Amodei just gave his first interview since the Pentagon blacklisted his company. The toll is visible on his face. He was asked one question. What would you say to the President right now? He didn’t hesitate. Amodei: “We are patriotic Americans. Everything we have done has been for the sake of this country.” Anthropic built their models to defend America. They were the first AI lab cleared for classified military systems. They wanted to help the warfighter. But the Pentagon demanded unrestricted access to fully autonomous weapons and mass surveillance of American citizens. Amodei drew the line. The government responded with emergency Cold War powers. A supply chain designation normally reserved for foreign adversaries. A six-month federal phaseout ordered from Truth Social. Amodei: “When we were threatened with supply chain designation and Defense Production Act, which are unprecedented intrusions into the private economy, we exercised our classic First Amendment rights to speak up and disagree with the government.” The administration framed Anthropic’s refusal as anti-American. Amodei’s response dismantled that framing in one sentence. Amodei: “Disagreeing with the government is the most American thing in the world.” Here is the deeper paradox nobody in Washington wants to say out loud. We are in a geopolitical race against autocratic adversaries who use AI for mass surveillance of their own citizens and autonomous weapons with no human oversight. The Pentagon demanded that Anthropic build those exact capabilities for America. Amodei: “The red lines we have drawn, we drew because we believe that crossing those red lines is contrary to American values.” You cannot defeat authoritarianism by adopting its methods. You cannot defend the open society by forcing private companies to build its antithesis under threat of wartime emergency powers. Anthropic held the line. Got blacklisted for it. And came out the other side saying the same thing they said going in. That is what it actually looks like to mean it.
This is bigotry, pure and simple. open.substack.com/pub/erininthem…
history is unfolding in front of us it's now obvious and evident to everyone with eyes to see why anthropic founding was a crucial fork in the timeline, and how catastrophic the counterfactual would've been otherwise still surprising though how fast it took to reach this point
A statement from Anthropic CEO, Dario Amodei, on our discussions with the Department of War. anthropic.com/news/statement…
I’m extremely disturbed and disappointed by the decision of a number of New York City hospitals to cease providing gender-affirming care to all patients under 19 years old. This decision, prompted by the Trump administration’s threat to withhold Medicaid funding at the direction of Attorney General Pam Bondi and HHS Secretary Robert F. Kennedy, Jr., will jeopardize the lives and well-being of their patients. Studies have shown that ending gender-affirming care after it has begun without patient consent can carry significant physical and mental health risks. For these young patients, gender-affirming care is life-affirming care.
