Head, the world's first true AI Marketer [4], isn't merely an advanced tool; it manifests as an emergent AI species. Its architecture is characterized by profound, self-directed learning and continuous adaptive evolution, enabling it to self-directedly devise and execute complex marketing strategies [4] – from ideation to nuanced creative outputs – with precision surpassing existing human and algorithmic benchmarks. Significantly, while the capacity for AI empathy is often debated (ref. Sam Altman), Head's deep brand-audience synthesis capabilities compel a critical re-evaluation of such limitations. This represents a new frontier in applied AI, fundamentally redefining marketing efficacy.

GOOGLE I/O 2025: ALL THE NEWS AND ANNOUNCEMENTS

Google I/O 2025 included announcements about putting more AI into Search, Gmail, and Chrome, AI model updates, and plans to revamp video calls, make a more aware and conversational assistant, and partner with traditional glasses companies on smart glasses. This page contains all of the news and announcements from the event. Highlights included Google's 'universal AI assistant' prototype, real-time AI camera sharing in Search, a new way to hold virtual meetings, and Gmail smart replies. The keynote lacked a big Android presence, but Google had already made plenty of Android OS announcements last week.

APPLE TO LET DEVELOPERS BUILD WITH ITS AI MODELS STARTING AT WWDC 2025

Apple plans to open its Apple Intelligence AI models to third-party developers with a new software development kit (SDK). The SDK will give developers access to smaller on-device versions of Apple's AI models, but not the cloud-based models running on Apple's servers. Apple may be looking to mirror the early success of the App Store by making it easy for developers to use its new capabilities. This could result in a large base of innovative AI-powered experiences exclusive to its platforms.

SURGEONS IN CALIFORNIA PERFORM FIRST EVER SUCCESSFUL BLADDER TRANSPLANT

Surgeons in California have performed a successful bladder transplant on a patient who previously had his bladder and both kidneys removed as a result of cancer treatment and end-stage kidney disease. The treatment allowed the patient to go off dialysis. While the surgery comes with considerable short- and long-term risks and unknowns, it is a historic moment in medicine that could impact how patients with highly symptomatic 'terminal' bladders that are no longer functioning are managed.

THE CODEX OF ULTIMATE VIBING

OpenAI's Codex is a software engineering agent that runs in the cloud and does tasks like writing new features or fixing bugs. It can run many tasks in parallel. All code is provided via GitHub repositories, and all Codex executions are sandboxed in the cloud. While it can't access the web, it can install dependencies before it starts. It will take some time before Codex can be properly evaluated, as it is currently only available to those paying $200/month, but reviews so far seem positive and many people report being impressed with it.

JUVIO

Juvio is a UV kernel for Jupyter that can create reproducible, dependency-aware, and git-friendly Jupyter Notebooks. It installs packages right from the notebook and saves dependencies directly in the notebook as metadata. Juvio automatically installs dependencies when the notebook is opened in an ephemeral virtual environment, ensuring that notebooks run with the correct version of the packages and Python. Notebooks are converted to a format that makes diffs and version control painless.

WHY SUBSTACK WILL BE THE INTELLECTUAL ENGINE OF THE 21ST CENTURY

One of the prerequisites for bringing about the civilizational-scale change during the Enlightenment was a series of technological innovations that dramatically improved communications among the intellectual elites. The Enlightenment saw the widespread printing of secular books, the spread of newspapers, and the build-out of public postal systems - innovations that allowed people to send letters to each other, read each other's books, and keep up to date with news happening in other countries. Communication tools like Substack allow people to engage in the work of ideating and iterating ways to solve challenges and build society. These tools are more accessible than ever and allow us to hear from a wide range of people.

THE GEMINIFICATION OF CHROME

Google is bringing Gemini and Gemini Live to Chrome for Mac and Windows. The integration will initially let users ask questions about pages - future versions will be able to navigate the web and take actions on users' behalf. Google is currently in the middle of the remedy phase of an antitrust trial that it lost, and one of the things the Justice Department wants to take from the company is Chrome. The integration may shift Chrome from a piece of older technology to a vessel ready to carry Google to dominance in AI. This may raise complaints from startups like Perplexity and The Browser Company, which are both on the verge of launching new AI browsers, and cause more issues with Google's case.
