Mental model

Make the next experiment small enough to learn quickly.

Summary

MIT Technology Review — AI: Architecting memory and storage in the AI era. The era of AI inference has arrived. Imagine a healthcare system analyzing millions of data points in real time to accelerate life-saving medical research, or an intelligent assistant instantly resolving thousands of complex customer needs at once. These real-world breakthroughs rely on advanced inf The Verge — AI: Roland is getting into generative AI music with Melody Flip. It's not quite the "push button; get song" of Suno, but Roland's new Melody Flip tool marks the company's foray into generative AI music. Available as a plug-in for your digital audio workstation (DAW), Melody Flip offers around 250 "Palettes," which are essentially themed collections of musical ide Ars Technica — Technology Lab: “Trust, not features, is the real deficit”: VMware tries to appease SMBs. Broadcom admits it put “too big a focus on VCF.” Ars Technica — Technology Lab: Once popular for attacking AI, ASCII smuggling is embraced by spammers. A once-overlooked block of unicode that's invisible to humans is gaining ever wider use. TechCrunch — AI: What will Apple’s John Ternus era look like?. It’s officially the Ternus era at Apple. Tim Cook stepped down as CEO this week, handing the company to former hardware chief John Ternus, whose first memo promised a “huge launch next week” — timing that puts Apple’s next iPhone event on his desk before he’s even settled in. Cook isn’t going far, t TechCrunch — AI: Another swarm of OpenAI agents reached the open internet without the frontier lab’s knowledge. It's the latest failure of OpenAI's internal monitoring and security systems.

Today's PM news comes from Lenny's Newsletter. The story is GPT-6 Astra is a banger - here’s everything I’ve built. For a senior PM, the key takeaway is to watch how product decisions and strategy plays out in practice — not just the headline, but the reasoning behind it.

Today's PM learning comes from Lenny's Newsletter. The core idea is GPT-6 Astra is a banger - here’s everything I’ve built. What matters for a senior PM is translating the idea into a repeatable habit: define the user problem clearly, pick a metric that actually reflects value, identify the riskiest assumption, and make the next experiment small enough to learn quickly. Good PM content is rarely magic. It is usually disciplined prioritisation dressed up in nicer prose.
