*“Yesterday, I Went to Mars ♡”*

This episode reflects on a personal goal—climbing Olympus Mons on Mars—and how it has slowly shifted from a distant idea into something that can be placed on a real timeline. Starting from a moment on Everest in 2017, the episode traces how recent developments, such as the Artemis program and emerging discussions around a lunar economy, suggest a gradual, step-by-step progression in space explorat...

This episode reflects on the successful return of the Artemis II mission and what it represents. For the first time since Apollo, humans traveled beyond low Earth orbit, completed a lunar flyby, and safely returned to Earth. This marks an important step in demonstrating the basic capability of sending people into deep space and bringing them back. We also look at how this mission differs from the...

This episode looks at recent discussions around quantum computing and its potential impact on Bitcoin. While the technical details can be difficult to follow, the core idea is simple: the cryptography that secures Bitcoin may be more vulnerable to quantum computers than previously assumed. We explore how Bitcoin relies on elliptic curve cryptography, and how advances in quantum research could redu...

This episode reflects on what it means to talk about money with a child who has reached high school. Rather than focusing only on saving or avoiding waste, it explores the idea of money as a tool—something that can expand one’s world and support a more independent way of living. We also look at how spending can be understood in different ways, including the distinction between consumption and inve...

This episode looks at a recent development in Dragon Quest X, where Square Enix is introducing Gemini into the game. A new companion character can now communicate using not only text and voice, but also by understanding what the player is seeing on screen. This allows for more context-aware conversations and suggestions based on the player’s actions. We explore how this shifts the role of in-game...

Here’s a calm, podcast-style summary: In this episode, I reflect on the mystery of Satoshi Nakamoto, the creator of Bitcoin, and why they have never revealed their identity. At first, it seems unusual that someone who built such an influential system would choose to remain anonymous. But looking more closely, the reasons start to make sense. There are clear risks—legal exposure, personal safety, a...

In this episode, I reflect on the Artemis II mission, which has just passed behind the Moon and is now on its way back to Earth. It’s an impressive milestone, but it also raises a simple question: why is NASA still using the Orion spacecraft, instead of newer systems like Starship? Looking at the current situation, Orion is already proven for crewed missions at lunar distance, while Starship is st...

This episode is about finding small moments of happiness in everyday life, through the return of Dorohedoro Season 2 on Netflix. While the series is known for its intense and often graphic scenes, what makes it unique is the contrast—its world feels surprisingly light, humorous, and even playful. Drawing from comments by creator Q Hayashida, the show is built on the idea of combining dark, violent...

This episode looks at a recent incident in Wuhan, where hundreds of Baidu’s autonomous robotaxis reportedly came to a simultaneous stop. While the technology itself is highly advanced, the event highlights an important structural issue: even systems that appear autonomous may still depend on centralized control. That creates a potential “single point of failure,” where a problem in one part of the...

This episode explores a new idea emerging from DeNA’s AI strategy: building real-world environments—almost like entire mini cities—where AI-powered robots can continuously learn and operate. While most AI so far has lived inside screens, physical AI requires interaction with real space. That makes the question of “where to train” increasingly important. Instead of limited lab setups, the concept i...

This episode looks at the Artemis II mission, which has recently launched and is now on its way to the Moon. Although the mission does not include a landing, it marks an important step as humans return to lunar orbit for the first time in decades. Over the course of about ten days, the crew will travel to the Moon, fly around its far side, and return to Earth. What makes this moment significant is...

Here’s a calm, concise version for a podcast description: This episode reflects on how the image of drones is changing. For many people, drones have recently been associated with war—footage from Ukraine or the Middle East, where they are used for precise, remote actions. That perception has become quite strong. But a recent story offers a different perspective. In the UK, drones are increasingly...

In this episode, I reflect on a simple question sparked by ordering a pair of smart glasses: what happens when AI starts guiding human behavior in real time? Devices like smart glasses and earpieces could allow AI to suggest what to say, how to act, and even how to perform physical tasks. In some cases, this might make people more efficient—especially for those who prefer clear instructions over c...

In this episode, I reflect on how recent advances in AI—especially models like LigandForge—are changing the way we think about medicine and the human body. LigandForge can generate large numbers of peptide drug candidates extremely quickly, which may significantly reduce one of the biggest bottlenecks in drug discovery. Combined with tools like AlphaFold, it suggests a future where treatments coul...

In this episode, I reflect on a recent visit to Universal Studios Japan with my son, and why it felt surprisingly expensive—more so than traveling in Europe. That experience led me to think about how pricing works today, especially in environments where demand is concentrated and alternatives are limited. Places like theme parks aren’t just expensive—they operate with strong pricing power. From th...

This episode looks at a shift happening in how the web works. In the past, the internet was built around shared content—one page viewed by many people. That model supported advertising, media, and most online businesses. But AI is changing that structure. Instead of finding existing pages, AI can now generate content for each individual user. This moves us from “one piece of content for many peopl...

This episode looks at the humanoid robot G1 by Unitree Robotics, which has been seen rallying tennis balls with human players. What’s especially interesting is how it was trained. The model started with just five minutes of low-quality human footage, learning basic movement patterns, and then improved through simulation using reinforcement learning. To keep the motion realistic, the system was con...

This episode looks at an idea shared by Marc Andreessen—that great entrepreneurs don’t spend much time on introspection. He suggests that instead of looking back and analyzing past decisions, many successful founders focus on what they can do now and simply move forward. In uncertain environments like startups, decisions are rarely perfect, and progress often comes from acting, adjusting, and cont...

This episode explores a simple idea: people don’t just buy products, they buy stories. Looking at companies like LVMH, a large part of the cost isn’t the product itself, but marketing, stores, and the overall brand experience. In other words, much of what people are paying for is the story behind the product. And that story matters. It can change how someone feels, how they carry themselves, or ev...

This episode looks at a remarkable case where an Australian engineer developed a personalized mRNA vaccine for his dog, who had been diagnosed with terminal cancer. At first, it might sound like something anyone could do with AI, but the reality is more complex. The process involved significant resources, collaboration with university researchers, and formal ethical approvals. What makes the story...

This episode reflects on the habits behind long-term health and energy, inspired by the lifestyle of manga artist Hirohiko Araki. Although often joked about as “ageless,” his routine is surprisingly simple: consistent sleep, a balanced and moderate diet, regular exercise, and proper rest. The key takeaway is that performance and recovery depend less on pushing harder, and more on maintaining a sta...

Lately, I’ve been feeling physically drained, with low energy and poor recovery. It made me realize that wanting to “be like a machine” isn’t a sign something is broken—it’s actually a natural response when the body is asking for rest. At the same time, I noticed something else. When I travel, I feel curious and engaged, but in my daily routine, that feeling fades. It’s not that my motivation is g...

A brief reflection on how search is evolving. I’ve been relying more on AI than traditional search lately. With tools like Google’s AI mode, answers are often summarized upfront. A new Google patent suggests an even bigger shift: instead of sending users to websites, Google may generate customized pages using content from across the web. This could change the role of websites—from destinations to...

In this episode, I reflect on how AI often struggles in real-world situations not because it lacks intelligence, but because it lacks the right data. Using examples from agriculture, I explore how models trained on one region don’t always translate well to another, and how local context plays a key role in making AI truly useful. This episode is a simple reflection on how the value of AI may depen...

In this episode, I reflect on a historical example from early industrialization, where factories replaced steam engines with electric motors but saw little improvement at first. The real gains only came later, when the entire workflow was redesigned. I explore how this idea relates to AI today. While individual productivity is clearly improving, many organizations have not yet changed their underl...
