APPLE TO LET USERS CHOOSE RIVAL AI MODELS ACROSS ITS IOS 27 FEATURES

Apple will allow users to select from multiple third-party AI providers to power features across its software. The change will be implemented in iOS 27, iPadOS 27, and macOS 27 this fall. Apple is looking to make it easy for customers to find a wide range of options on its devices rather than building the best AI software or services. The shift will give users more flexibility and benefit partners like Google and Anthropic.

10 TRILLION SAMPLES A DAY: SCALING BEYOND TRADITIONAL MONITORING INFRA AT DATABRICKS

Databricks rearchitected its monitoring infrastructure to handle over 10 trillion samples daily and five billion active timeseries by transitioning to a customized timeseries database called Pantheon, which has self-healing and efficient tiered storage. This new architecture also uses an advanced aggregation pipeline to manage metric cardinality and a Lakehouse-native platform named Hydra for high-cardinality troubleshooting and 50 times cheaper data storage.

GEMINI APP GETTING FULL REDESIGN THAT OVERHAULS EVERY PART OF THE UI

Google's Gemini app is receiving a comprehensive UI overhaul featuring a pill-shaped prompt box, a colorful pulsating gradient background, and a redesigned homepage greeting. The update consolidates tools like Images, Videos, Canvas, and Deep Research into a unified bottom sheet with a media carousel, while the model picker returns to the top-left as a dropdown. On iOS, the redesign makes heavy use of Liquid Glass, though broader rollout details for Android remain unclear.

THE CASE FOR STRATEGIC ILLEGIBILTY

Making your company legible to AI could result in the commoditization of your own moat. Founders need to be building two versions of their company right now: the company that humans work inside and a digital twin that AI agents can navigate, query, and operate in. They need to consider what things should be deliberately kept out of the AI system to protect their advantages. The highest-value things to keep partially illegible are the things that make the company weird, specific, and hard to copy.

BLUE ORIGIN MOON LANDER COMPLETES TESTING AT NASA VACUUM CHAMBER

Endurance is an uncrewed lander funded by Blue Origin to advance Human Landing System capabilities in support of NASA's Artemis program. It will demonstrate precision landing, cryogenic propulsion, and autonomous guidance, navigation, and control capabilities in support of future lunar surface operations. Endurance will carry two NASA science and technology payloads under the Commercial Lunar Payload Services initiative to the lunar South Pole region this year. It was developed under a public-private partnership model, with Blue Origin conducting work through a reimbursable Space Act Agreement.

I'M SCARED ABOUT BIOLOGICAL COMPUTING

A few months ago, a company released a video showing how it grew neurons in a lab and got them to play DOOM. The scientists fed visual data to the neurons, which reacted to that data in some way to play the game. This could mean that the company built a human biocomputer and then put it into a simulated hell, playing the same game on a loop. While it was 'just a science experiment', the biocomputer had more neurons than a jellyfish or a worm. There's a large commercial incentive to continue developing the technology, but the ethical implications are still unclear.

CLAUDE CODE IS NOT MAKING YOUR PRODUCT BETTER

At the frontier, it's not clear that spending on tokens produces any economic value at all. The bottleneck at that level is tastemakers. The taste to delete, compress, and refuse is more valuable now that the floor is rising. AI makes it possible for anyone to create generic products, but it won't help the highest-level artisans create better products.
