OpenAI safety employee resigns, claiming the company’s ‘culture is broken’
TechCrunch 1 week ago 35 ● 16 sources
David Robinson resigned from OpenAI after writing an essay in The Atlantic saying the company’s culture is broken. He said he spent 3.5 years at OpenAI and had led the safety reports that accompanied major product launches. OpenAI said it is continuing to improve safety measures, while Robinson’s departure adds pressure for broader culture and alignment changes beyond new rules or laws.
AI is speeding up exploits. Vulnerability spreadsheets can’t keep up.
The New Stack 1 week ago 42
Cybersecurity teams are finding that AI-driven software production and faster exploit development are widening the gap between the number of CVEs they can identify and the number they can investigate and fix. The article points to the collapsing time-to-exploit window, making long, sequential manual triage unworkable. Vulnerability management is shifting from counting spreadsheet entries by CVSS severity to continuous, contextual risk prioritization using production scanning, reachability/context, and threat-intel signals.
We need a Department of AI, or we risk pushing the U.S. economy over the brink
Fortune 27 ● 18 sources
The author argues that appointing an AI czar is not enough because repeated AI incidents and weakening public/investor trust could trigger a broader pullback that harms the U.S. economy. In 2025, Amazon, Meta, Alphabet, and Microsoft invested $400 billion in data centers alone. The proposed change is to create a fully staffed Department of AI with authority to set pre- and post-deployment risk frameworks, run audits, impose fines, and draft faster legislation to reduce risk and preserve investment confidence.

'We can't trust them completely': AI research fellows warn that labs are running models with the safeguards off behind closed doors
Fortune 4 ● 18 sources
AI policy researchers at GovAI said major AI labs can run powerful models with key safeguards turned off and that published safety evaluations may not match real internal usage. They pointed to Sept. 29 as the briefing date and cited that internal safeguards were not deployed, with tools failing to reliably review agent behavior. As a result, they argue for independent auditing and warn that more real-world deployment in development and testing could increase safety problems in models or codebases.
