Rome and the Illusion of Empire

-
Image
Rome has a way of resurfacing when you’re not looking for it. Not just in history books, but in places where it doesn’t quite belong at first glance. In science fiction empires that span galaxies. In fantasy legions marching under unfamiliar banners. In systems that feel vast, ordered, and strangely permanent. I have felt that pull for as long as I can remember. As a child reading Asterix , I was supposed to root for the unruly Gauls. But I often found myself staring instead at the Roman camps: the straight lines of tents, the palisades, the almost hypnotic order of it all. Later, much later, I remember watching lectures about the Roman grain economy—how food moved across the Mediterranean at scale, how the city of Rome itself depended on invisible systems of logistics and administration. That was probably the moment it clicked. Rome was not just an army or a culture. It was a machine for stability . From a distance, the system looks permanent. And once you start seeing that, you be...

The Assassins of Thasalon by Lois McMaster Bujold — When Small Stories Start to Add Up

-
Image
Long-running novella series can easily start to feel insubstantial. Self-contained, pleasant, forgettable. The Assassins of Thasalon avoids that trap. If anything, it makes the opposite case: that short, tightly constructed stories can gather weight over time without ever needing to announce that ambition too loudly. A Quiet Return, With Complications The setup is deceptively simple. Penric, sorcerer, physician, and frequent magnet for complications, is drawn into a mission connected to a failed assassination attempt and the long-shadowed history of Thasalon. What begins as investigation gradually turns into something more layered: part political entanglement, part moral problem with no especially clean edges. Bujold keeps the scope controlled. There is no need for grand battles or an inflated cast assembled just to create the impression of scale. Instead, the novella moves with precision. Each development adds pressure, and each answer has a way of making the situation more compli...

When the Mask Becomes the Self: Identity and Impersonation in Fiction

-
Image
If everyone believes you are someone else, at what point does it stop being a disguise? Stories built around impersonation often begin with a practical problem. A king is missing. A fortune must be accessed. A plan requires someone to take another person’s place, convincingly and quickly. The premise is simple: resemble the original closely enough, learn the necessary details, and maintain the performance. At first, identity in these stories appears surprisingly fragile. It depends less on who someone is than on whether others accept the role they are playing. But the longer the performance lasts, the more complicated that assumption becomes. What begins as something external—something worn like a costume—has a tendency to move inward. The role reshapes the person performing it. Becoming the Other Person In its most classical form, the impersonation story is almost clean in its logic. In The Prisoner of Zenda , an Englishman is persuaded to impersonate a kidnapped king. The success ...

What We Learned from Ukraine—and Why It May Not Matter

-
Image
For decades, global supply chains have been optimized for efficiency. Inventory minimized, production concentrated, redundancy stripped out wherever possible. It is a system designed to work smoothly under normal conditions—and it often does. Until it doesn’t. The Trade-Off We Understand There is a persistent idea that systems can be optimized either for efficiency or for robustness, but not both. That is too simplistic. In practice, systems sit somewhere in between. But the trade-off is real. Every buffer removed improves margins. Every dependency consolidated reduces cost. And each of those choices makes the system a little less able to absorb shocks. The question is not whether we understand this. It is whether we can act on it. Recent tensions around the Strait of Hormuz bring that question back into focus. A narrow passage carries a disproportionate share of global energy flows. It is efficient. It is not particularly robust. And like many such chokepoints, its risk is e...

If AI Can Create New Knowledge, Why Do We Still Need Humans?

-
Image
Recent AI systems have started to produce outputs that do not merely rearrange familiar material, but appear to push beyond it. In mathematics, there are already examples—early, limited, but real—where models help uncover structures or solution paths that had resisted human attention for years. In creative fields, the same pattern shows up in a different form: not just imitation, but variation that feels genuinely new. That raises an obvious question. If AI can produce novel content, why worry about running out of training data? At that point, wouldn’t the system become at least partly self-sustaining? It is an appealing idea. It also turns out to be less straightforward than it first appears. The Fear Was Never About Running Out of Text The weakest version of this debate is easy to dismiss. The internet is not about to run out of words, images, or videos. And even if human-generated material became a smaller share of what is published online, AI could simply generate more. B...

The Rules of Time Travel: And Why They Never Agree

-
Image
Time travel may be the most deceptively simple idea in science fiction. Go back. Change something. Come home. It sounds straightforward—almost intuitive. And yet, the moment you start looking closely, the idea begins to fracture. Not because it is impossible, but because every story seems to follow a different set of rules. In some, the past is fixed. In others, it splinters into branching timelines. In a few, the very act of trying to change time is what causes the events you were trying to avoid in the first place. There is no shared framework, no underlying agreement—only competing interpretations of how causality might work if we were allowed to step outside of it. Time That Cannot Be Changed The Anubis Gates by Tim Powers All You Zombies— by Robert A Heinlein Predestination (film adaptation) Some time travel stories eliminate paradoxes entirely—not by resolving them,...

From Liar’s Poker to the Financial Crisis: How Wall Street’s Culture Created Modern Risk

-
Image
Liar's Poker is one of those books that makes the recent past feel strangely distant. Reading it now, what stands out is not just how excessive the 1980s were, but how foreign the world it describes already feels. The Wall Street of shouting traders, crowded bond desks, and market edge built on access and instinct is close enough to recognize, yet far enough away to seem almost unthinkable. Two impressions kept returning as I read. First: the 1980s must have been a genuinely wild period in finance. Second: Wall Street does not just attract ambition; it attracts characters, and occasionally produces someone larger than life. At the center of Liar's Poker sits Lewis Ranieri, who feels almost mythological in retrospect. Starting in the mailroom and rising to lead the mortgage division at Salomon Brothers, he helped build a business that effectively printed money in the mid-1980s. It is easy to read his story as a pure version of the American Dream. But that reading is a li...
