iOS 27 Is Here. It's Time to Meet the New, Improved Siri (7 minute read)

iOS 27 marks the beginning of an iPhone divide: only Apple Intelligence-capable models will get Siri AI and other AI-powered features. The new Siri AI uses Google's Gemini models to answer questions. It can look through users' private data, but Apple says it doesn't store user data and that neither Apple nor Google can access it. This article provides a summary of the new capabilities Siri AI has as well as the new features available to all iPhones with iOS 27.

A journey to the heart of history's largest nonterritorial empire (92 minute read)

For 23 years, the single fact dominating every moment of every room Mark Zuckerberg has been in is the fact that he is Mark Zuckerberg. Today, his empire has 3.6 billion users, has a market capitalization of $1.6 trillion, and has averaged the addition of a zero to its valuation roughly once every US presidential term. It's not a normal situation for a human being to be in. This article takes a look at how Zuckerberg built his empire, the problems he faces at the top, Zuckerberg's various other ventures, and more.

A beginning for mathematics (18 minute read)

It will be impossible to stop people, amateur or professional, from pushing a button to produce mathematics. The field shouldn't only be reserved for graduate students and the like. There's now more interest in maths than at any other time in history, and that's a good thing. This will bring an abundance of new maths. The only difference is that some questions will now be answerable via a cash injection.

For the first time, the US military confirms it has deployed weapons in orbit (14 minute read)

The US has officially announced the existence of space control weapons in orbit. Pentagon leaders have become more open to discussing space warfare in recent years, so the deployment is not entirely unexpected. The announcement didn't include details about the weapons. The deployment of space technology often takes years, so the weapons program has likely spanned multiple presidential administrations.

"Do You Still Read the Code?" (18 minute read)

There are at least two ways to have AI assist in programming: one is to use it to help understand and interact with the implementation, and the other aims to remove the need for that interaction altogether. These are different paths, so they require different tools and different approaches. The goal of someone using AI to further their understanding is not to become a vibecoder, and ceasing to read code isn't, in itself, progress.

AI Labs Want Someone to Stop Them (26 minute read)

If all of the AI labs slowed down, they would collectively spend less on compute, and they'd also be able to charge frontier-model prices for a longer time. However, if they all got together in a room and agreed to slow down, that would look like an antitrust conspiracy. It is generally illegal for competitors to get together and agree to limit the output of their industry. If they all published papers about how important it is to slow down, and the government believes those papers, it might help them coordinate.

Apple's Siri AI Can Be Swapped Out for Claude, ChatGPT, Code Shows (5 minute read)

Apple has designed its new Siri architecture to work with third-party AI models at a surprisingly deep level. One mechanism called Model Delegation allows Claude to appear as a Siri extension in the same way as the existing built-in ChatGPT extension. It appears that Claude hands tasks back to Siri if a request requires access to an Apple system feature. An inference provider option allows Apple's own server-side Siri model to be completely replaced by another model.
