AI agents that cooperate without sharing secrets, Imbue's case for Personal Computing 2.0, Slovenia's .si domain surges after Trump's super intelligence order, Apple tightens macOS Full Disk Access, and the first radio signal detected from an exoplanet
Hello, dear TEA-mates! Here is what you need to know today.
1. 🔐 AI Agents That Cooperate Without Sharing Secrets
In a September 30 essay, Liam Horne argues that as everyone gets an agent holding private calendars, messages, company documents, and code, those agents will need to find collaborators without exposing their owners' data. He points to three tools from Ethereum and cryptography research: secure multiparty computation (MPC), fully homomorphic encryption (FHE), which lets a cloud server calculate on encrypted inputs it cannot read, and trusted execution environments (TEEs). In his example, two agents check whether salaries of $150,000 and $155,000 are within $10,000 of each other, revealing only "yes" while the server returns a cryptographic proof that it ran the approved calculation. Because this compute is expensive, Horne expects agents to pay for each check, perhaps a tenth of a cent through MPP. A million agents each checking once every ten minutes would create about 1,700 payments per second, the kind of load a fast, low-cost stablecoin network like Tempo is built for. (Read More)

2. 💻 Imbue Calls For A Personal Computing 2.0
Imbue's Josh Albrecht argues it is time for a second personal computing revolution. He describes how the 1995-era computer that "did what you told it" gave way to subscriptions, login screens, ads, and lock-in, and says closed AI labs, which trained on scraped books and web content, now sell that knowledge back to users. His alternative, Personal Computing 2.0, rests on one principle: your data is yours. From that he derives a few requirements: computing must be cross-platform and multi-vendor, so tools like Claude, Muse, and Dot can work together and be scripted, and users must be able to move instantly between a laptop, an old desktop, a Raspberry Pi, or a rented cloud machine. He argues open-weight models are now nearly good enough to run locally and even operate closed agents on a user's behalf, forcing AI companies to compete on cost, performance, and reliability instead of lock-in.

3. 🌐 Slovenia's .si Domain Surges After Trump's Super Intelligence Order
Registrations of Slovenia's .si domain have spiked since President Trump signed an executive order directing government agencies to call "AI" and "artificial intelligence" "SI" and "super intelligence." Registry SI reported a 2,199% increase in .si purchases in September, with 11,000 new addresses recorded on September 30, the day after the order, and almost 13,000 more in a single 24-hour period. Hostinger says .si is now its second most popular extension after .com, with about 4,300 registrations on September 30 and 5,400 on October 1, more than half from buyers in the U.S. and India, though only about 3% are explicitly AI-related. Wix reported no meaningful uptick. Hostinger's head of domains says Slovenia will not repeat Anguilla's .ai windfall: .si costs about $12 a year and the money goes to the registry, while .ai costs about $90 with a two-year commitment and funds Anguilla's government.

4. 🍎 Apple Tightens macOS Full Disk Access Because Of AI Agents
Apple announced new controls on macOS Full Disk Access, a setting originally designed so backup apps could work and which lets an app read files, mail, messages, and browsing history. The move came days after Inc. columnist Jason Aten reported that Meta's Muse AI agent on Mac knew the content of his private messages without his permission, a claim Meta disputes, and after a Wired report on a flaw in ChatGPT's Mac app that could have let hackers grab sensitive data. In a developer blog post, Apple said "some developers are using Full Disk Access in ways that could put users at risk," and that users who want to grant this "extraordinary level of access" will now have to take "very explicit user action." Apple added that "as AI agents become increasingly capable and autonomous, the risks associated with this level of access will grow substantially." (Read More)

5. 📡 Astronomers Detect The First Radio Signal From An Exoplanet
Astronomers say they have directly detected the first radio emission from a planet outside the solar system, and it points to a colossal magnetic field, not intelligent life. Using MeerKAT, an array of 64 radio dishes in South Africa, a team led by Harvard doctoral researcher Kevin Ortiz Ceballos traced repeating radio bursts to Beta Pictoris b, a gas giant about 12 times the mass of Jupiter, 63 light-years from Earth. The signal is an auroral radio emission, and coauthor Edo Berger says the planet's magnetic field is at least 200 times stronger than Jupiter's. Earlier hints of exoplanet radio signals could not be separated from their host stars, but this team localized the emission to the planet itself and recorded it "multiple times, at multiple frequencies." The paper, posted to arXiv on September 15, is still under peer review, and outside scientists urge caution until it is confirmed. (Read More)

🛠️ Skill of the Day
The Hype Filter: turns any big science or tech headline into what was actually found, what is still a guess, and what to watch next.
You are a careful science and technology editor who explains things to smart
non-experts. I will paste a headline and article about a new discovery, product,
or breakthrough.
Step 1. In two plain sentences, say what was actually observed or built.
Step 2. Sort every major claim into three groups: Shown (backed by data in the
article), Claimed (stated by the authors or company but not yet checked by others),
and Speculation (what commentators or the headline imply). Quote the line from the
article that supports each one.
Step 3. Tell me the status: peer reviewed, preprint, company announcement, or
single source. Explain in one sentence what that means for how much I should trust it.
Step 4. List three questions a skeptical expert would ask, and what result would
make the story bigger or smaller.
Use only what is in the article. If something is missing, say "not stated."
Here is the article:
