The Oura Ring Doesn't Catch My Naps

*“Yesterday, I Went to Mars ♡”* ·

2026/10/05

This episode looks at the gap between what a wearable device promises and what it actually delivers — specifically, the experience of buying an Oura Ring to track total daily sleep, only to find that naps and back-to-sleep sessions often go unlogged.To fill in the gaps, about ninety days of Oura data was layered with Apple Watch and Garmin data through Apple Health. That cross-referencing revealed something concrete: on one particular day, Oura logged six hours of sleep, while Apple Watch had

When AI Starts Suggesting What Your Life Could Be

*“Yesterday, I Went to Mars ♡”* ·

2026/10/04

This episode sits with a question that's hard to shake: if AI can now suggest not just how to do something, but what to do — and eventually, maybe even why — what is there left for a person to decide?It traces that question through a specific, concrete goal: being on Mars at age 71, in 2049. The plan is already taking shape through swimming, English study, and saving money. But the unsettling thought is that a sufficiently capable AI might have suggested that whole life direction before the idea

The Day Asia's Richest Man Was Sentenced to Life in...

*“Yesterday, I Went to Mars ♡”* ·

2026/10/02

This episode looks at the rise and fall of Hui Ka Yan, founder of China Evergrande Group, following his sentencing to life in prison in August 2026 — and the question that first comes to mind: can you really be imprisoned for life just for running a company into the ground?The answer, it turns out, is that the fraud was staggering. In 2019 and 2020 alone, revenue is said to have been overstated by roughly $80 billion, while Hui himself received around $4.2 billion in dividends during those same

Yayoi Kusama Never Stopped Saying "Look at Me"

*“Yesterday, I Went to Mars ♡”* ·

2026/10/01

This episode looks at Yayoi Kusama — not just her work, but the person behind it, and how learning more about her life changed the way her art appears.It touches on a detail that reframes everything: at 29, with limited English and almost no reputation, she moved alone to New York in 1958 and actively pushed her way into the city's art world — approaching galleries, seeking out critics, pursuing recognition with a determination that drew criticism at the time. She was not waiting to be

Something I Noticed While Bouncing Ideas Off an AI

*“Yesterday, I Went to Mars ♡”* ·

2026/10/01

This episode follows a question that started as a feeling of progress and turned into something less comfortable: whether using AI as a thinking partner actually sharpens your thinking, or quietly reinforces what you already believed.The specific worry that surfaces is this — if the questions you ask an AI are shaped by what the AI already explained to you, and if every round of pushback eventually ends with the AI saying "ah, that's a sharp point," then the whole exchange might be

A Wonderful Future, If You Can Afford It

*“Yesterday, I Went to Mars ♡”* ·

2026/09/29

This episode looks at "Common People," the first episode of Black Mirror season 7, and what it's like to return to the show after a long gap and find it still doing exactly what it does best.The episode follows a woman who loses part of her brain function to illness and is kept alive through a cloud-based service called Rivermind — which then gradually shifts its terms, adds restrictions to cheaper plans, and eventually begins serving advertisements through her voice.What makes it land

Who Will Make ChatGPT's Eyes?

*“Yesterday, I Went to Mars ♡”* ·

2026/09/29

This episode looks at a realization that came from researching Meta's AI glasses and their "Muse" model: that the real question in the AI race might not be who builds the smartest brain, but who gives that brain the best eyes.It traces a shift in thinking — from watching which AI model is most capable, to noticing that no matter how capable AI gets, humans are still doing the work of showing it the world. Taking out a phone, photographing something, describing it, sending it. That gap

What AI Glasses Are Really For: A Tool for Humans and...

*“Yesterday, I Went to Mars ♡”* ·

2026/09/27

This episode looks at how a passing mention of Meta's AI assistant Muse — buried in an article about Mark Zuckerberg's wealth ranking — led to a longer chain of thinking about what AI glasses are actually for.The central observation is about a gap that still exists even with highly capable AI: getting information to the AI is still manual work. Taking out a phone, snapping a photo, describing a scene out loud. The AI itself has become remarkable; the bridge to it hasn't caught up.What

AI, Electricity, and Space

*“Yesterday, I Went to Mars ♡”* ·

2026/09/27

This episode looks at what it actually means, in physical terms, to build AI infrastructure at scale — and what a force majeure notice filed by Oracle over a New Mexico data center project made that feel like for the first time.Following the chain from AI back to its foundations leads somewhere unexpected: not software, but land, permits, cooling systems, transmission lines, and power generation. The episode traces that chain slowly, letting the weight of each constraint accumulate.From there, it

The Right to Turn Off Recommendations

*“Yesterday, I Went to Mars ♡”* ·

2026/09/25

This episode looks at algorithmic recommendations — what they do quietly, and what it might mean to have the option to turn them off.It starts with a small, familiar moment: opening Instagram to post a photo for the shop, then surfacing thirty minutes later having watched strangers talk about things never searched for. That gap between intention and outcome is what the whole episode turns on.There's a distinction drawn between two very different ideas — a ban, which says don't look, and an

Just 5 Millimeters Higher, and Time Runs Differently

*“Yesterday, I Went to Mars ♡”* ·

2026/09/25

This episode looks at a newly announced atomic clock, built using an element called lutetium, that drifts by only one second over 260 billion years — and what that level of precision actually makes possible.It touches on Einstein's general theory of relativity, and the idea that time passes more slowly where gravity is stronger. A difference of just five millimeters in height is enough, with a clock like this, to produce a measurable difference in how quickly time passes.From there, the episode

*“Yesterday, I Went to Mars ♡”* ·

2026/09/24

This episode looks at something noticed through daily AI conversations: the smarter AI gets, the more the human side of that exchange seems to matter.A central image here is the "handover notebook" — the idea that AI memory works less like human recall and more like a written log that needs to be filled in deliberately. The longer you work with AI, the more clearly you have to articulate what you care about, how you work, and what a good answer even looks like.It touches on how this plays

When I Started a Small Eyewear Shop in Shinjuku,...

*“Yesterday, I Went to Mars ♡”* ·

2026/09/22

This episode looks back at opening a small eyewear shop in Shinjuku eighteen years ago, and what it meant, even then, that customers were finding the shop through a daily blog.It traces how that early shift — from foot traffic to written words pulling people in — connects to something much larger that has unfolded since: the idea that attention, time, and behavioral data have become resources in their own right, concentrated in the hands of a few large companies. What people searched for, which

When You Can Still Turn Back, You Can't Stop Comparing

*“Yesterday, I Went to Mars ♡”* ·

2026/09/22

This episode sits with a single line — "when you can still turn back, you can't stop comparing" — and follows where it leads.It looks at the particular restlessness of uncommitted moments: the job you're not sure about, the direction you haven't fully chosen, the decision you're still second-guessing. When the exit is still visible, it's hard to settle into where you are.There's a set of quiet observations about how the road beside yours always seems to have better

Problem, Progress, or the Collapse of Authority

*“Yesterday, I Went to Mars ♡”* ·

2026/09/21

This episode takes the arrival of AI as a starting point for thinking about how new technologies get interpreted differently depending on where you're standing — and uses the printing press as the central analogy: one machine that looked like a problem to manuscript copyists, an opportunity to publishers, and a threat to ecclesiastical authority all at once.It also introduces the concept of the "automaton" — not the science-fiction robot, but something quieter: a loop where AI systems

A Line from Chanel

*“Yesterday, I Went to Mars ♡”* ·

2026/09/20

This episode looks at a quote attributed to Coco Chanel — "I only drink champagne on two occasions: when I am in love, and when I am not" — and what makes it so quietly effective.It touches on how the line works: she's simply saying she drinks champagne all the time, but by dividing it into two occasions and leaving a small gap, it becomes something you remember. The structure does the work.There's also a reflection on language itself — how the same thought, said differently, can

Show Her Beautiful Things

*“Yesterday, I Went to Mars ♡”* ·

2026/09/18

This episode reflects on a remark made by an eye doctor during a routine visit — not about correcting a problem, but about something quieter: that a young person should be able to see the world as clearly as possible, so that beautiful things look the way they deserve to.It touches on the difference between vision that functions and vision that notices — the individual leaves on a distant tree, the layered colors in an evening sky, the brushwork in a painting, city lights without smeared edges

What "Two Life Sentences" Actually Means

*“Yesterday, I Went to Mars ♡”* ·

2026/09/17

This episode looks at the phrase "two life sentences" — what it actually means legally, and why a system designed for one lifetime would hand down more than one.It traces the logic back to a real case: a 21-year-old student in the United States who got into the wrong car in 2019, believing it was her Uber. The driver had modified the vehicle so she couldn't get out. She was abducted and killed. The sentence that followed — life for murder, life for kidnapping, five years for weapons

I Saw Nolan's Odyssey — and Came Away Thinking About...

*“Yesterday, I Went to Mars ♡”* ·

2026/09/17

This episode begins with walking into Nolan's Odyssey almost completely unprepared — no prior reading of the myth, no particular expectations — and finding that what lingered afterward wasn't the monsters or the battles, but something harder to name.It's a reflection on what Odysseus actually represents as a figure: not the strongest hero, not the most fearless, but someone who has simply been through an extraordinary amount — war, loss, deception, capture, wrong decisions — and each

Wallace Stevens, and the Question of How to Live

*“Yesterday, I Went to Mars ♡”* ·

2026/09/16

This episode looks at Wallace Stevens — twentieth-century American poet, Pulitzer Prize winner, and lifelong vice president of an insurance company — and what his story quietly unsettles about the way we tend to think about work and calling.It touches on a familiar narrative: find what you truly want to do, then leave everything else behind. Stevens never made that move. Neither did Chekhov, who called medicine his lawful wife and literature his mistress. Neither did William Carlos Williams, making
