This is huge news. I have spent the past 6 months wondering wtf was up with Amazon: they filed 380,000 AI-related CyberTipline reports to NCMEC in the first half of 2025.

Turns out ALL of it was known CSAM they found by screening their AI training data. It's NOT AI-generated or AI-morphed CSAM.

This is courage. Looking a masked, government fascist dead in the eye, face to face, knowing full well that your life is on the line.

If elected officials had 1/10th of Alex Pretti's resolve, we would have far fewer troubles.

Reminds me of a passage from Kurt Vonnegut's Timequake. Can't fit the whole thing here, but the key part goes: "... the situation is social rather than scientific. Any work of art is half of a conversation between two human beings, and it helps a lot to know who is talking at you."

Beware of OpenAI's 'Grantwashing' on AI Harms | TechPolicy.Press J. Nathan Matias and Avriel Epps say OpenAI's announced research funding is the perfect corporate action to make sure we don't find answers for years.

Should scientists apply to OpenAI's fund for research on AI & mental health? Should policymakers consider it a credible safety effort?

Avriel Epps & I see it as "grantwashing," and it's an insult to anyone whose loved one's death involved chatbots. We explain:

"Captain Gains" on Capitol Hill
Shang-Jin Wei & Yifan Zhou
WORKING PAPER 34524
DOI 10.3386/w34524
ISSUE DATE November 2025
Using transaction-level data on US congressional stock trades, we find that lawmakers who later ascend to leadership positions perform similarly to matched peers beforehand but outperform them by 47 percentage points annually after ascension. Leaders' superior performance arises through two mechanisms. The political influence channel is reflected in higher returns when their party controls the chamber, sales of stocks preceding regulatory actions, and purchase of stocks whose firms receiving more government contracts and favorable party support on bills. The corporate access channel is reflected in stock trades that predict subsequent corporate news and greater returns on donor-owned or home-state firms.

Google has moved from moral cowardice (removing ICE tracking apps) to direct complicity in the violent, unconstitutional abuse of vulnerable people.

As a civil liberties lawyer who worked at Google for ten years, this one hits me in the gut.

The Right-Wing Attack on Wikipedia The free internet encyclopedia is widely used to train AI. That’s why conservatives are trying to dethrone it.

New from me: β€œworking the refs” has come for Wikipedia. The same type of attacks alleging anti-conservative bias that right wing politicians have make about social media are coming for the encyclopedia β€” because of its critical role in shaping AI answer engines.
