*“Yesterday, I Went to Mars ♡”*

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...

In this episode, I reflect on an idea about AI and creativity: that what matters is not whether AI was used, but whether something could have been created without you. As AI makes average output increasingly easy and inexpensive to produce, value may shift toward work that is more personal and less replaceable. I share some thoughts on how this applies not only to music, but to work and creative o...

In this episode, I talk about a concept I recently came across called the “God Squad,” a committee in U.S. environmental law that can grant exceptions to endangered species protections. I share what I learned about how it works, how rarely it has been used in the past, and why it is starting to come up again in discussions around large infrastructure and energy projects. More than the system itsel...

In this episode, I reflect on an idea I came across in a newsletter by Satoshi Nakajima. As AI and automation continue to reduce costs, the real shift may not be efficiency alone, but the ability to do things at a scale that was previously unrealistic. I talk about how this change could affect areas like content creation, education, infrastructure, and even space logistics. Many ideas that were on...

In this episode, I talk about a recent development involving “cyborg cockroaches” being equipped with small devices such as cameras and sensors, and guided through electrical stimulation. What once felt like science fiction is now becoming technically possible through the combination of AI, bioengineering, and miniaturized electronics. Rather than focusing on the details alone, this episode reflec...

In this episode, I talk about a recent visit to Dohdaira Observatory in Chichibu. I went hoping to see the stars, but the sky was completely cloudy and the observation was cancelled. Even so, the trip made me think about motivation. We often wait until we feel motivated before taking action, but in many cases motivation only appears after we start moving. I also reflect on how small actions—even o...

A short reflection inspired by Marcel Mauss’s classic book The Gift . Mauss wrote that when the benefits of a gift are kept only for oneself, something important begins to fade. He wasn’t speaking literally about death, but about how talents, trust, and relationships can slowly dry up when the flow of giving stops. In this episode, I reflect on the idea that many things in life—knowledge, opportun...

In this episode, we talk about the internet slang “Claudepilled.” The term comes from the idea of the “red pill” in The Matrix and describes a moment when using an AI tool—especially Claude—changes the way someone approaches work. Once people experience how these tools can help with writing, organizing ideas, or understanding complex context, it can become difficult to go back to older workflows....

In this episode, we reflect on the leadership style of the polar explorer Roald Amundsen , who reached the South Pole in 1911 and safely returned with his team. His famous line, “Adventure is just bad planning,” points to a simple idea: careful preparation and practical decisions can make the difference between success and failure. By comparing Amundsen’s expedition with Robert Falcon Scott’s, we...

In this episode, we look at a quote from the polar explorer Roald Amundsen : “Adventure is just bad planning.” At first, it sounds surprising. Explorers are often associated with risk and bold decisions. But Amundsen, who successfully reached the South Pole in 1911 and returned safely with his team, believed that careful preparation was the real key to exploration. By comparing his expedition with...

In this episode, I reflect on something I’ve been thinking about while raising four daughters: parenting often feels like a process of growing as a parent myself. When children show difficult behavior, it can be easy to focus on correcting them. But many times it also reveals something about our own reactions, patience, and maturity as adults. Parenting reminds us that children learn less from wha...

In this episode, we reflect on how everyday technology is changing our sense of privacy. Devices like smart glasses with built-in cameras are making it easier than ever to record and share what we see, often from a first-person point of view. While this can create new kinds of content online, it also raises questions about people who may appear in videos without realizing it. The conversation also...

In this episode, we look at a court case in New Zealand that raised an interesting question about AI and human expression. A defendant submitted a very well-written apology letter, but the judge later realized it appeared to have been generated by AI. This led to a simple but important issue: when words are produced by a machine, how should we understand them as a sign of genuine remorse? The disc...

In this episode, we talk about a simple way to recognize ultra-processed foods. One useful guideline is to check the ingredient list: if it contains many items you wouldn’t normally find in your own kitchen, it may be highly processed. We also discuss why these foods often taste so appealing. Many are designed around what scientists call the “bliss point,” a balance of salt, sugar, and fat that ma...

In this episode, I talk about a Japanese private rocket company called Space One and the idea of turning space launches into something like a “space delivery service.” Traditionally, rockets were large national projects that launched only occasionally, carrying many payloads at once. But companies like Space One are aiming for a different model: using small rockets to launch small satellites more...
