Good morning. It's Friday, October 2 and we're covering how AI models are becoming powerful hacking tools, the movement shaping AI safety, and Google’s plans to take AI computing into space.
Plus: a Friday Fact on the brain’s hidden plumbing system, and an essay on OpenAI’s vision for an agent-powered digital future.
SpaceX is launching two Planet Labs prototype satellites carrying Google Tensor Processing Units, or TPUs, the chips Google builds for AI. The test is part of Project Suncatcher, a plan to learn whether solar-powered data centers could someday work in space despite radiation, cooling and debris risks.
Anthropic estimates that today’s robots can perform about three-quarters of physical job tasks, equal to 34% of all U.S. working hours. But robots cost less than human labor for only 0.3% of work, and at the historic pace of price declines it would take about 40 years to reach 10%.
China’s new rules cover AI services that imitate human personalities and hold ongoing emotional conversations. They require clear notices that the AI is not human, add protections for minors and ban systems from encouraging emotional dependence, self-harm or irrational decisions.

Six Takeaways From OpenAI’s Big DevDay
To a packed house of developers, Sam Altman and crew released a passel of new products and capabilities, thrilling the faithful and serving notice that OpenAI is moving quickly toward its own particular Altmanesque vision of the agentic future.
There were more than 20 announcements, which is a considerable number of things to digest in one sitting, but the underlying proposition was reasonably simple and utterly predictable. → Read the full article here.
CYBERSECURITY
Open AI Models Are Becoming Powerful Hackers
Tenzai, an Israeli cybersecurity company, won a three-month HackerOne contest by using GLM-5.2 and GLM-5.3 from the Chinese company Z.ai. In the authorized competition, as many as 30 AI agents worked together to find flaws in live networks, including an airline server that could reveal app users’ locations and a call-center system exposed through a database attack.
GLM is an open-weight model, which means people can download and modify the software behind it. That gives defenders a tool they can run on private networks, but it also makes safety limits easy to remove; researchers told The New York Times they expect more attacks before defensive systems catch up. Watch whether companies begin using the same agents to test their own systems continuously instead of waiting for a human audit. → Read the full article here. (Paywall)
AI ETHICS
The Movement That Taught AI Labs to Fear the Future
Effective altruism began as a movement that asked how charitable money could help the most people. It later turned much of its attention to the chance that powerful AI could harm humanity, and its followers helped start OpenAI and Anthropic because they believed people who understood that risk should guide the technology.
The Economist argues that the movement was early to take AI risk seriously, but warns against reducing every moral choice to a giant math problem. If a small group believes it knows what is best for billions of people now and in the future, individual rights can disappear from the calculation. Watch how much influence this community keeps as governments push AI companies to move faster, not slower. → Read the full article here. (Paywall)

FRIDAY FACT
The Brain's Drainage System Was Described in 2012
In 2012, researchers led by Maiken Nedergaard described what became known as the glymphatic system: a network of pathways around blood vessels that helps move cerebrospinal fluid through brain tissue and carry waste away.
A 2013 follow-up study found that in sleeping or anesthetized mice, the space between brain cells increased by about 60%, while beta-amyloid was cleared roughly twice as fast as during wakefulness.
The finding suggested that one important function of sleep may be giving the brain more opportunity to clear waste. Beta-amyloid is one of the proteins that accumulates in Alzheimer's disease.
The exact mechanics are still being studied, especially in humans, but the discovery changed how scientists think about how the brain cleans itself.
