Five layers. Seventeen minutes. One structure built to last for decades. This is Stage 4: Lamination. Heat, vacuum pressure, and precision engineering transform glass, EVA, and solar cells into a fully sealed solar module ready for the next phase of production. This is where individual components become energy infrastructure.

Two layers of printed lines. One on the page, one on a clear film. Slide the film. That's it. That's the whole technology. The moiré effect has been known since the 19th century. Kurashima bound it between two covers.

Nuxt layers might be the most powerful and underrated composability pattern ever. Here's why: The Nuxt MCP Toolkit is a module that lets you create MCP servers in your Nuxt app in the easiest possible way. But here's where it gets interesting. The module doesn't just create a server. It automatically scans every layer in your application and extends MCP tools from all of them. Meaning you can add tools from any layer. The composability is insane. Now imagine this: Docus ships with the MCP Toolkit built in as a layer. Every single Docus documentation site now has an MCP server running by default. But that's not even the best part. Because we use the @aisdk on top of the MCP, each doc site gets a fully functional agent that connects to that MCP server. Zero configuration. Deploy to @vercel with Gateway and it all just works. Out of the box. Every documentation site gets its own AI agent powered by MCP. One layer. One module. Infinite scale. This is the power of Nuxt's architecture. Layers let you compose functionality that cascades across every application that uses them. You build it once, and it works everywhere.

Infrastructure layers form when fragmentation can no longer scale. Before cloud: companies had to manage their own infrastructure. The fragmentation became too expensive to sustain. Cloud platforms like AWS created a shared infrastructure layer. The industry rebuilt on top of it. Healthcare is reaching the same inflection point. Fragmented human health signals. Siloed institutions. Non-interoperable systems. Life AI BioHub is the coordination layer forming now. Cloud did it for computation. We’re doing it for human health.

Today’s #China# news had many layers. @realDonaldTrump in Beijing; Xi hosting a high-stakes summit; @elonmusk making faces... But for me, there was another very human moment. I spotted a familiar face on TV: Cheng Lei. We used to do TV crossovers back in the CCTV days, when I was at @Reuters which had a partnership with CCTV for financial news. (That kind of partnership is almost unimaginable today.) And Cheng Lei was one of the most recognizable English-language business anchors in China. Sharp, professional, fluent across cultures. A face of China’s opening to the world. Then one day - she was arrested as a spy! In 2020, Cheng Lei was detained in China. She was accused of supplying state secrets overseas and spent more than three years in custody before being released in 2023. By her own account, the ordeal was not only legal or political. It was deeply human: isolation, uncertainty, separation from her children, and the mental pressure of being caught inside something much larger than herself. She lost 1,154 days. And today, there she was again — on Australian television, analyzing Trump’s China visit. That image gave me déjà vu — and goosebumps. Because U.S.-China relations are not only about tariffs, semiconductors, Taiwan, AI, supply chains, or state banquets. They are also about people. Journalists. Translators. Entrepreneurs. Students. Families. Immigrants. People who once believed they could move between worlds, explain one side to the other, and build bridges through language, trust, and shared curiosity. Some of those bridges are now broken. Some became dangerous and some people paid a very real price. Cheng Lei’s story is a reminder of how quickly the world can change — and how personal geopolitics can become. The silver lining is - after years of silence, she can return to the screen with her own voice. That is resilience. Watching her today, I felt both a sense of sadness and admiration. Sadness for the world we lost. Admiration for a woman who survived, came home, rebuilt her life, and returned to journalism on her own terms. In the middle of another Trump-Xi summit, maybe this is the angle worth remembering: Great power politics is never abstract. Behind every diplomatic reset, every strategic rivalry, every headline about “China” and “America,” there are human lives being reshaped. And sometimes, the most powerful story is not only the leaders on the stage. It is the familiar face who made it back to the screen. 🫶
