THE SIGNAL CHATS THAT COST OPENAI RESEARCHERS THEIR JOBS

Three OpenAI safety researchers were fired after security officers discovered Signal chats with disappearing messages turned on on their personal devices.

ANTHROPIC BUILDS ITS OWN SOURCE CONTROL SYSTEM

Anthropic employs around 3,500 staff, but its coding output is closer to that of a company with 35,000 to 70,000 staff.

‘IF ANYTHING HAPPENS TO THIS GUY … EVERYONE IS SCREWED'

This article features an interview with Surý where he discusses the unfolding AI-cybersecurity crisis, how the internet's infrastructure is maintained by small crews of volunteers, and how it feels to save the web.
