‼️ Google's September Android update patches a vulnerability that lets an attacker run code on a phone remotely, with no permissions and no user interaction required. Google won't say which flaw it is.
Eight critical System bugs in this bulletin lead to remote code execution. In total there are 200 fixes, of which 33 are critical.
Google has said that 40 percent of Android phones no longer receive updates at all. Which is concerning, to say the least.

‼️ An Anthropic researcher says AI could kill us all before 2030 and his is opinion is shared throughout the AI industry. He says senior researchers and executives soften their language for the press while voicing the same fear privately.
In the most aggressive scenarios, he said, things could be out of control by the end of 2027.
He also worked at OpenAI and is now leaving the industry altogether because neither company is acting responsibly: both are racing toward self-improving superintelligence with everyone's lives on the table.
He also takes on the obvious objection, if they believe this, why keep building?
At OpenAI, he says, many people have not really internalized the stakes. At Anthropic they are well understood, but the company is locked in a race to get there first.
The researcher told he had moved to Anthropic only months ago because of its safety reputation, that he thinks the safety work there is sincere, but that it isn't enough: trade-offs become unavoidable when labs are competing with each other and with Chinese rivals.
What he asks for is coordination rather than exits: pacing agreements between U.S. labs, and if it comes to it, a temporary halt on improving model capabilities.

Wild: NVIDIA founder & CEO Jensen Huang says Artificial General Intelligence (AGI) has officially arrived 😳
And it appears to run on exactly the thing Jensen sells...
Compute.
GPT-6 Astra was trained on 100,000+ NVIDIA Grace Blackwell GPUs. Another 400,000 are coming online next.
Meanwhile, NVIDIA has committed up to $100B to OpenAI’s infrastructure buildout, while backing even more AI data center financing elsewhere.
But if Jensen says AGI has arrived, AGI has arrived 🤷♂️
