   人畜無害はノーリスク・リターンな徳である

   Is being harmless the same as being a good person? In this episode, I question why modern society often treats harmlessness as a moral virtue. Traditional virtues such as courage, justice, generosity, and honesty usually involve some kind of cost: risk, conflict, sacrifice, or responsibility. Harmlessness, however, can often be achieved simply by avoiding conflict, strong opinions, and difficult situations. There is nothing wrong with living quietly and peacefully, but not harming others is different from actively doing good. Perhaps we have begun giving too much moral credit to people…

   AIで空いた時間に、仕事をしてはいけない

   What should we do with the time AI saves us? In this episode, I argue that efficiency should not simply lead to more work. If a task that once took three hours now takes one, perhaps the remaining two hours should belong to us. We can play games, read, walk, nap, or do nothing at all. Modern life often turns even rest into another productivity tool, but rest does not need to justify itself. AI and automation should not exist merely to increase the density of work. Their real promise may be giving human beings more time in which they do not have to work.…

   苦しみの資産化 ── なぜ不幸はYouTubeで価値を持つのか

   What happens when human suffering becomes an asset? In traditional accounting, humiliation, loneliness, unemployment, and painful memories have no monetary value. But on YouTube, those same experiences can generate views, donations, subscribers, and advertising revenue. In this episode, I explore the strange economics of turning personal suffering into content. The most disturbing possibility is that success may create a conflict: you want to escape your suffering, but your audience may value you precisely because you suffer. When unhappiness becomes profitable, recovery can reduce your…

   深いことを言いすぎる時代

   Why does everyone sound so “deep” these days? In this episode, I explore the inflation of philosophical language online: words like freedom, meaning, identity, structure, desire, and authenticity now appear everywhere. The problem is not thinking deeply, but mistaking abstract language for depth itself. When profound-sounding words are used constantly, philosophy can become little more than background music. I argue that the weight of a thought may depend partly on how long someone has remained silent before saying it. Perhaps true depth comes not from speaking endlessly about life, but from…

   壁打ちは環境負荷が高い

   Is AI “brainstorming” bad for the environment? In this episode, I half-jokingly ask whether we really need data centers running around the world just to help us organize our thoughts. People now use AI to reflect on their careers, emotions, goals, values, and daily frustrations—tasks that once required only a notebook, a walk, or a quiet evening. Of course, AI has many valuable uses, but perhaps not every vague feeling needs computational power. Sometimes the most environmentally friendly form of reflection is simply thinking for yourself, writing something down, or doing absolutely nothing…

   なぜ私たちは『相談』ではなく『壁打ち』と言いたがるのか

   Why do people in business increasingly say “sounding board” instead of simply asking for advice? In this episode, I explore my discomfort with the Japanese business buzzword kabeuchi , literally “hitting a wall.” Behind this seemingly harmless expression may lie something revealing about modern work culture: we want other people to help organize our thoughts, but we do not necessarily want their opinions, disagreement, or criticism. I discuss the hidden cost of using someone else’s time, why AI may actually be a more ethical sounding board, and what this trend tells us about our relationship…

   普通の人間であることが、最も差別化になる時代

   In an age of AI, optimization, and personal branding, being an ordinary human may become a powerful form of differentiation. More people are following the same formulas: quitting jobs, becoming freelancers, building personal brands, exercising, investing in themselves, and using AI to optimize everything. As our content and lifestyles become increasingly polished and similar, imperfect people may become more interesting. Someone who hesitates, changes their mind, wastes time, or follows an irrational obsession can feel surprisingly authentic. In this episode, I explore why “natural” human…

   コンフォートゾーンから出るな

   “Get out of your comfort zone” is one of the most common messages in self-help culture. But is staying comfortable really such a bad thing? In this episode, I question the idea that we must constantly challenge ourselves, improve, grow, and seek new experiences. A comfort zone can also be a place of stability, recovery, and safety—a base we can return to after taking risks. Modern self-improvement culture often makes ordinary, peaceful living feel like stagnation. Perhaps we do not need to escape our comfort zones. Maybe we simply need to leave them when necessary—and return without feeling…

   Vlogなら物語を作らなくていい、という誤解

   Vlogs may look simple: just film your daily life, meals, work, shopping, and weekends. But keeping viewers interested over time is much harder than it seems. Once people become familiar with the same room, routines, and places, the novelty begins to disappear. Successful vloggers need to find small stories inside ordinary life—changes, goals, challenges, decisions, and developments that give viewers a reason to return. At the same time, too much staging can make a vlog feel artificial. In this episode, I explore the difficult balance between authenticity and storytelling, and why vloggers…

    社会の命令を自分の欲望として内面化した人間のほうが、よほど効率よく動く

    What if modern society no longer needs to give us orders because we have learned to command ourselves? In this episode, I explore how social expectations can become personal desires. We wake up early, exercise, study AI, improve our careers, manage our health, and chase productivity because we believe we freely chose these goals. But did we? The more powerful form of control may be the one that feels like freedom. When society’s expectations become an inner voice, no supervisor is necessary. True freedom may begin when we question whether the destination we are pursuing is really our own.…
