The episode also connects this to a perspective from the merchant side, wher...

This episode reflects on a recent experience with the repair and replacement process for a Pixel Watch purchased through the Google Store. While the product issue itself was straightforward, the support process became unexpectedly complex, involving repeated escalations, mixed language communication, and different instructions from global and local support systems. We explore how large-scale syste...

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...
