Apple Takes on AI Wearables With Always-Listening Watch Features (4 minute read)

The Apple Watch Series 12 and Ultra models have new Audio Intelligence tools that use ambient listening to take high-level notes of wearers' conversations throughout the day. The devices will also have a Live Recap function that can show a transcription of what was said in a live conversation in the last 15 seconds and be able to listen to important sounds, such as a crying baby, doorbells, or sirens. These features will not create or store recordings, and Apple will not be able to access the raw audio. They will be available to test in English later this year. The improved Siri is being rolled out on watchOS 27 in beta on September 14.

Genome language models can design cancer vaccines (32 minute read)

Modern cancer-vaccine design involves identifying mutations, predicting presentation, predicting immunogenicity, ranking targets, and designing RNA. However, biology is complicated, and whether a target makes a good vaccine candidate depends on all kinds of information. This makes cancer vaccines an unusually direct test of whether AI models can take what it has learned from biology and apply that knowledge to design a medicine for one particular human being.

Scenarios for our Economic Future (12 minute read)

It is unknown yet whether AI will lead to unprecedented growth or widespread unemployment. Anthropic's Economics team built a model to understand how AI might affect jobs, growth, and unemployment in the US in the coming years. The model found that AI will lead to adverse impacts on wages and job prospects for knowledge workers in scenarios where growth is faster than anything in economic history, and in those scenarios, the challenge will be making sure wealth is broadly shared. The answer will depend on how AI affects all the tasks that make up the economy, the new tasks it creates, and how fast AI takes on this work.

It covers how PostHog built a custom rasterizer that runs hundreds of concurrent jobs across many pods.

Tailwind Labs is joining Shopify (3 minute read)

Tailwind is joining Shopify, one of the first companies operating at scale to see the potential of Tailwind CSS and start building with it. Shopify has invested in making sure Tailwind is actively maintained and will continue to provide a stable long-term home for the project. Nothing will change with Tailwind CSS or any of Tailwind's other open source projects, but the project will no longer try to grow its business. All existing customers will maintain access to their products, but Tailwind has closed signups for new customers.

Mullenweg remains on the board of directors.

Cracks in the AI Thesis Part 2 (4 minute read)

The price of AI is coming down. However, volume growth may not be large enough to counteract the effective decline in prices. The models driving volume increases are relatively cheap, standard models. These trends do not appear to be driven by the adoption of open-source models or Chinese models.
