*“Yesterday, I Went to Mars ♡”*

A quiet reflection on how children often learn more from what adults do than from what they say. This episode explores the idea that being a good example does not mean being perfect. Sometimes, apologizing honestly, trying again after failure, or simply continuing forward with humility can teach more than advice ever could. It also touches on a simple but grounding thought: maybe we don’t need to...

This episode looks at a recent development where Anthropic gained access to SpaceX’s large-scale supercomputer, raising questions about how competition in AI is evolving. Rather than a simple rivalry, the situation highlights a separation between AI models and the infrastructure that powers them. Companies may compete at one level while still relying on each other at another, especially as demand...

This episode looks at how search is shifting from keyword-based queries to more natural, context-rich questions. In the past, users had to simplify what they really wanted into a few keywords. Now, with AI, it’s becoming possible to describe a situation more fully and receive answers that reflect that context. Rather than just listing links, search is moving toward assembling more direct responses...

Podcast Summary A recent story from China’s entertainment industry highlights how AI is beginning to reshape even creative fields. Actor Zhang Xiaolei, who had appeared in over 200 short dramas, reportedly lost work as AI-generated actors became more widely used. He was known for playing a recurring “tyrant CEO” role in short, mobile-first dramas—content designed for speed, scale, and repetition....

Naoya Inoue once said that what excites him most before a big fight isn’t just physical preparation, but facing pressure and his own mind. This perspective is unusual. Most people experience pressure as something to avoid. But he approaches it as an opportunity to sharpen himself. The reflection connects this idea to personal experience in extreme situations, where composure breaks down and one’s...

This episode reflects on how the feeling of “surprise” can fade in a highly convenient world. With information arriving in advance and AI anticipating what comes next, there are fewer moments where we naturally notice something unexpected. As a result, the habit of observing small changes—something that once happened more automatically—can become weaker over time. The episode explores the idea tha...

This episode reflects on the idea that the growing sense of “personal responsibility” may not come from a colder society, but from one that no longer requires as much help to function. Many everyday tasks—navigation, health information, communication, even administrative work—can now be handled individually through digital tools and services. As a result, situations where people naturally rely on...

Summary (Podcast) This episode is a simple reflection on organizing a few cameras and noticing how their roles have changed over time. Looking at four devices—the original GoPro Max (2019), GO 3S, GO Ultra, and X5—it becomes clear that the differences are not just in specs, but in how they fit into a workflow. Newer models handle low light better, produce cleaner images, and integrate more smoothl...

This episode looks at a report from Proton claiming that Google users carry an invisible price tag — some valued at around $19,000 a year to advertisers, others at just $34 — and what it actually means to use a "free" service. It touches on a comparison drawn from the eyewear business: just as the cost of materials is only a fraction of what a customer pays for frames, Google's real...

In recent years, we’ve heard a lot about AI transforming medicine. Terms like mRNA and peptides often appear in that context, which can make them seem like entirely new inventions. In reality, both have been studied and used for decades. mRNA functions as a kind of blueprint inside our cells, while peptides are the molecules created from those instructions. Technologies like mRNA vaccines or pepti...

This episode follows a Tuesday morning run past Oji Shrine, where a leaf blower working through the grounds sparks a small but genuine question: does efficiency actually diminish a place, or does it simply not matter? The turning point comes from a newsletter by Satoshi Nakajima, who wrote about the shock of seeing leaf blowers introduced at Meiji Jingu — workers in white coveralls, engines runnin...

This episode looks at news of Google reportedly committing up to $40 billion to Anthropic — the company behind Claude, a direct rival to Google's own AI, Gemini — and the question of why anyone would pour that kind of money into a competitor. The answer turns out to be structural: if Gemini wins, fine; if Claude wins, Google still profits as a major shareholder. It calls to mind sending climbe...

Today’s topic is about space and comfort—specifically, whether lower ceilings help children feel more at ease. I recently heard that some childcare facilities intentionally design lower ceilings because it helps kids feel calm. At first, that felt counterintuitive to me, since I usually prefer open spaces. But thinking about past experiences, I realized it’s not just about how big a space is. Bein...

Recently, I’ve been working a lot with AI on my own computer—running models like Gemma and building small tools. While doing that, I read a paper by Terence Tao about how human thinking should evolve in the age of AI. One point stood out. Until now, technology helped us share what we create. But AI is starting to create itself. That’s a big shift. Tao also talks about the “smell test”— that intuit...

A short reflection on running AI locally for the first time. After installing Google’s Gemma 4 on a Mac, this episode explores what it means for AI to work offline. Even without internet access, it can answer questions and handle basic tasks, which feels surprisingly natural. The key takeaway is about “tokens,” the unit AI uses to process text. Even when there’s no cost, there are still limits—esp...

A short reflection on a small but noticeable shift in everyday digital experiences. After receiving a Mercari notification to confirm receipt just minutes after delivery, this episode looks at how systems are becoming faster than our actual routines. What used to be occasional messages from eager sellers now seems to be automated prompts driven by real-time logistics and platform updates. It also...

This episode reflects on starting to use Git for the first time at 47, and the experience of learning something completely new from scratch. It touches on the shift from understanding a concept in theory to actually feeling it through hands-on use—especially the idea that Git allows you to move forward without fear because you can always return to a previous state. There’s also a simple analogy co...

This episode reflects on a shift in how AI is being used—from browser-based interactions to working directly through the terminal. It touches on why text-based control aligns better with how AI models operate, and how tools like Claude Code are making this approach more practical. There’s also a simple introduction to Git as a way to track changes and create “save points” when building or modifyin...

This episode shares a real example of a phishing email that appeared to be an invitation to the American Express Centurion Card. At first glance, it looks convincing—using familiar branding and language—but a closer look at the sender’s domain, the invitation method, and the overall context reveals clear inconsistencies. We walk through a few simple checks that can help identify these scams, and w...

This episode explores how increased use of AI is changing everyday workflows, especially through voice input. We look at the role of smartwatches in capturing ideas quickly, comparing experiences with Apple Watch Ultra 3 and Google Pixel Watch 4. The discussion touches on the differences between Apple’s note-based approach and Google’s more search-oriented system, and how each shapes the way infor...

This episode reflects on revisiting an older Intel-based Mac Pro while testing a lightweight AI model like Gemma 4. Although the machine was once considered high-performance, running modern AI workloads highlights a clear gap compared to newer Apple Silicon systems, particularly in speed, efficiency, and thermal behavior. The experience leads to a broader observation about how quickly hardware can...

This episode explores the idea that electronics and vintage items exist on very different timelines. While vintage products tend to gain character and value over time, electronics gradually lose value—even when unused—due to both physical deterioration and rapid technological change. We look at how newer models quickly redefine what is considered current, and how that shapes the way we perceive ol...

This episode looks at Google’s release of Gemma 4, a lightweight AI model that can run directly on smartphones.
