MARK ZUCKERBERG DIRECTED META TO CREATE A PREDICTION MARKETS APP

Mark Zuckerberg recently dispatched a small team at Meta to create a smartphone app similar to Polymarket and Kalshi. The app uses a points system rather than real money, but Meta has not ruled out the eventual use of real money betting. Internally referred to as 'Arena', the app will function independently from Meta's other apps. The effort is part of a broader purchase at the company to create new types of apps based on emerging social behavior online.

WITH STARFALL, SPACEX EYES AN EDGE IN GLOBAL CARGO DELIVERY FROM ORBIT

A SpaceX Falcon 9 rocket lifted off yesterday with a new saucer-shaped reentry pod called Starfall. The secretive mission's purpose is reportedly to support the transport and delivery of goods through space. Most of what is known about Starfall comes from the FAA's environmental assessment, which says that Starfall will enable point-to-point delivery of critical cargo through space on rapid timelines and provide access to space for commercial in-space manufacturing. Starfall is designed exclusively for cargo and is smaller than SpaceX's human-rated Crew Dragon spacecraft.

WAR BY OTHER MEANS

The use of robots in war will only increase. All signs point towards governments relying on a much smaller pool of human capital for labor and war. The use of unmanned munitions drives down costs and lessens the need for humans on the battlefield without weakening deterrence. This means that a fundamental source of political power has begun to shift from the people towards the firms that make the machines.

AGENT STUCK ON A CAPTCHA? BROWSERBASE LOGS IN, NAVIGATES, AND FINISHES THE JOB.

CAPTCHAs and login walls are where most agents quit. Browserbase gives yours a browser that can sign in, get past the block, and carry on—on any site. It's self-healing when pages change and scales to thousands of concurrent sessions, which is how 10K+ teams, including Ramp and Lovable, run 35M+ sessions a month.

THE COMING LOOP

Agent loops are enabling teams to build at astonishing speeds. However, their use reduces developers to the role of merely a messenger. Looping is powerful, but it removes responsibility and encourages people to give in to the machine. While agent loops are likely going to be the future, it's important for developers to retain good judgment and ensure the rules of good engineering are kept.

THE PROBLEM IS PROMPT DEBT

Treating natural language as a specification language for engineering quietly caps what you can build. Prompt debt increases as additional guidance is added to instructions to nudge models into line. These prompts, full of edge cases and threats to the AI, become impossible to comprehend for teams. Prompt debt locks developers into older models, possibly making them miss potentially cheaper, faster, and better models.

NSA LOST ACCESS TO POWERFUL AI MODEL AMID ANTHROPIC DISPUTE

NSA cybersecurity analysts were testing versions of Anthropic's tools when export controls were imposed on the company. The tests found that Mythos was able to identify cybersecurity flaws within the NSA's classified network quickly. Analysts were impressed with Mythos' capabilities in controlled test settings. There is an effort to push forward a classified contract between Anthropic and the NSA that would allow the agency to use the company's AI technology for a variety of purposes, but that contract has not been finalized.

DEAD PLAYERS

Founders used to aim for the stars. iPhones, social networks, large language models, and cryptocurrency are the sort of non-linear increments that were either created by accident or in the process of trying to do the impossible or unprecedented. The non-linear option is now more impersonal and lower-risk than ever. This means people who have no personal reason to take risks and pursue a moonshot are more likely to try anyway.
