It never made sense to regulate C02 via the EPA's pollution rules, it's just too different from other forms of pollution. Carbon taxes are the right mechanism. www.nytimes.com/2026/09/13/c...

Makes sense to allow stay-at-home parents to collect child care subsidies as a substitute for hiring someone else for child care. Then the subsidy is accessible to all parents! www.nytimes.com/2026/09/05/u...

Trump Officials Draft Plan to Pay At-Home Parents, Using Funds for Working Ones
The proposed benefit, a top policy priority for Vice President JD Vance, would apply only to married couples and tap a fund intended to provide federal child care subsidies to working parents.

FWIW, I think the question of "Did Woke 1 go to far?" it depends on where you ask! On college campuses? Sometimes. In making cops responsible for bad behavior? Obviously not! In holding sex pests and criminals to account? Clearly incomplete, look at the damn White House.

The solution to AI safety is not to train closed models so that they never "press the nuclear button." Because we can't stop the bad guys from finding workarounds or using open models. The solution is formal security guarantees that models don't have nuclear buttons to press.

That One Non-Profit Governance Trick: Experts make decisions in a smoke-filled room, keeping information private so they can "roll out" decisions in the right way. Then make the wrong decision because there was no community input and get massive community push-back as a result.

So apparently AI use (mostly undisclosed) is becoming ubiquitous in ACM paper submissions. I don't think this happens in my group so I was surprised to hear it. But if that's actually the case, perhaps requiring disclosure is pointless. Thoughts?

A note from our editors:
Note from the editors:

ProPublica is publishing the names of the two federal immigration agents involved in the fatal shooting of Minnesota protester Alex Pretti. We believe there are few investigations that deserve more sunlight and public scrutiny than this one, in which two masked agents fired 10 shots at Pretti as he lay on the ground after being pepper-sprayed. 

The Department of Justice said it is investigating the incident, but the names of the two agents have been withheld from Congress and from state and local law enforcement.

The policy of shielding officers’ identities, particularly after a public shooting, is a stark departure from standard law enforcement protocols, according to lawmakers, state attorneys general and former federal officials. Such secrecy, in our view, deprives the public of the most fundamental tool for accountability.
