GOOGLE'S FIRST SUNCATCHER ORBITAL DATA CENTER TEST LAUNCHES OCTOBER 1

Project Suncatcher is a moonshot effort by Google to design orbital AI data centers. Its first experimental satellite will launch on October 1. Its aim will be to validate Google's vision for a constellation of AI satellites. The satellite, about the size of a refrigerator, has four custom TPU AI accelerators and solar panels that supply about one kilowatt of power. It will serve as a test of several technologies over its few months of operation.

WAYMO IS SCALING FAST: HERE'S WHAT THE FLEET DATA SHOWS

Waymo appears to be concentrating its efforts in just two states. 80% of its roughly 4,000 robotaxis are in California and Texas. Waymo's fleet has grown by nearly half in the past three weeks in Texas. The company's remaining 800 or so vehicles are spread across cities in other states, including Arizona and Florida. A growing number of the vehicles in Waymo's fleet are Chinese-built minivans.

THERE'S A NEW WAY TO BREAK RSA THAT'S FASTER THAN ANYTHING WE'VE SEEN BEFORE

Researchers have discovered a novel method that uses classical computing to reduce the current RSA security level to an unacceptably low threshold. The practical risk is limited, but still significant. Widely used RSA implementations are also safe. The technology involves signature forgery and reduces the required computing resources by orders of magnitude.

A NEW TREND OF CPU SHORTAGES

Many companies are struggling to source CPUs. CPU spot pricing has disappeared because there's no longer any lack of demand for CPUs. It's now nearly impossible to get CPUs on spot instances without long-running connections with cloud providers. Reserving specific CPUs now needs to be done months in advance. Cloud providers will even turn down certain reservations because they don't have enough CPUs or the right type of CPUs.

THINKING IN SYSTEMS, SHIPPING IN LOOPS

AI has removed the typing from software engineering but left the system design. What's left is designing the loop that decides whether the output is right. Great system design is defined by resilience, self-organization, and hierarchy. Resilience is AI checking its own work, self-organization is the loop learning, and hierarchy is the layering of skills, tools, and sandboxes into composable components that are reused once verified to work.

THE SPECTER OF NEURALESE

Neuralese recurrence is a hypothetical technology that would allow AIs to think dangerous thoughts without getting detected. OpenAI's new Astra model uses a reasoning technique called recurrent depth that makes the model's chain of thought more difficult to monitor by allowing it to operate outside of the sequential thinking that characterizes most reasoning models. There is an emerging taboo on creating dangerous neuralese AIs. It is unclear whether OpenAI broke that taboo, as a clear line has yet to be drawn.
