AI presents a fundamental threat to our ability to use polls to assess public opinion. Bad actors who are able to infiltrate panels can flip close election polls for less than the cost of a Starbucks coffee. Models will also infer and confirm hypotheses in experiments. Current quality checks fail

Last week, OpenAI finally released GPT-5, which many had hoped would usher in the next significant leap in A.I. capabilities. But it is just the latest product to suggest that A.I. might not get much better.
What If A.I. Doesn’t Get Much Better Than This?
GPT-5, a new release from OpenAI, is the latest product to suggest that progress on large language models has stalled.

Yesterday, the Commission proposed piling a whole heap of new goals—from competitiveness to defense—onto the EU’s regional policy.

Rubio’s position seems to be:
- We get to say who is a terrorist. Our decision is final. It can’t be challenged. Just trust us.
- Once we decide you are a terrorist, we can immediately deport you. No judges.
- After we deport you, we can make you rot in a foreign prison. No criminal charges needed.

On Hugh Hewitt’s show, Marco Rubio says El Salvador is “housing” people sent by the US. But he never says on what possible legal authority? These people haven’t committed any crime in El Salvador and by their own admission “many” have never committed a crime in the US. It all seems entirely lawless.

This is exactly what the Erdogan regime used to do (before it got all the compliant courts it needed): remove judges that rule against it.
JUST IN: DOJ is asking the DC circuit to remove Judge Boasberg from the case over Trump’s invocation of the Alien Enemies Act.
Hard to see the circuit doing this, but the ask itself is extraordinary. storage.courtlistener.com/recap/gov.us...
