The Computism Trap

Why an oven can never understand the 'smack' of a propane torch

By Liam Spradlin · 12 min read

Editor's note: A warning against the belief that every human experience can be reduced to a data point.

In a Silicon Valley basement, the air was thick with smoke. A team of researchers and chefs were testing prototype ovens, attempting to engineer the perfect culinary experience through automation. The goal was simple: Michelin-grade meals at the touch of a button. Yet, the kitchen was chaotic. A chef had attempted to sear lamb using a technique that required the instinctual heat of a propane torch—a move the oven's logic could not interpret. To the machine, the chef's instinct was a bug, a deviation from the programmed path. This tension reveals the core conflict of modern technology: the attempt to turn subjective human sensation into objective, repeatable data.

The Death of Agency

The engineers viewed human intervention as a liability. If a user adjusted a temperature or changed a timing, they were creating 'bad habits' that threatened the machine's perceived intelligence. The mantra on the office whiteboards was 'change the ritual'. This is the essence of computism—the ideology that the universe is a series of solvable equations. By abstracting the process away, the technology promises the end result without the effort. But in doing so, it strips away the agency of the person using it. We are no longer cooks; we are merely operators of a black box.

An oven can’t taste. It has no idea what 'smacking' something with a propane torch means.

This abstraction is what philosopher Albert Borgmann called a 'device'. A device delivers the ends while hiding the means. You get the meal, but you lose the connection to the craft. When we turn taste into data, we aren't just making cooking easier; we are making it hollow. We are attempting to count the petals of a cherry to understand its flavour, a task that is fundamentally impossible because data cannot capture the embodied experience of being alive.

The failures of the smart kitchen model

The inability to translate sensory intuition into code
The reduction of human skill into 'bad habits'
The loss of agency through extreme abstraction
The category error of treating subjective taste as quantifiable data

As we move further into an era of automated decision-making, we must ask what we are losing in the trade. If we successfully automate every nuance of our lives, we may find ourselves living in a world that is perfectly efficient and entirely tasteless. The struggle is not between humans and machines, but between the richness of human subjectivity and the sterile certainty of the algorithm.

Key Takeaway

Data can describe a thing, but it can never experience it.

The Ghost in the Synapse

Investigating the mystery of terminal lucidity

By Ariel Zeleznikow-Johnston · 10 min read

Editor's note: A look at the biological anomalies that challenge our understanding of memory.

An 81-year-old woman in an Icelandic retirement home had not spoken to her family in a year. Her Alzheimer's had stripped her of recognition and language. Then, suddenly, she sat up, looked her son in the eye, and recited a poem with perfect clarity. Within a month, she was gone. This is terminal lucidity: the unexpected return of cognitive function in patients facing death. It is a phenomenon that defies the current understanding of neuroscience, which suggests that a brain ravaged by dementia should be incapable of such a feat.

The Biological Contradiction

By the time a patient reaches the end stages of dementia, their brain is physically compromised. Synaptic connections have disintegrated, and the brain has visibly shrunk. Standard medical logic dictates that cognition should decline steadily until the end. Yet, reports of terminal lucidity suggest that memories—stored in the very structures that are decaying—can suddenly become accessible. This implies that our current models of memory storage might be incomplete. If the physical substrate is gone, where does the information reside?

If a dying brain can spontaneously access 'lost' memories, perhaps we could induce a living brain to do the same.

The implications for medicine are massive. Current treatments for Alzheimer's, such as lecanemab, focus on removing protein accumulations for minuscule gains in slowing decline. But terminal lucidity suggests a natural mechanism for restoration exists, even in the most damaged systems. If we can identify the trigger for this sudden clarity, we might move from merely managing decline to actually restoring function.

The challenges of studying terminal lucidity

The physical degradation of neural circuitry
The potential for observer bias in hospice settings
The lack of a known biological trigger
The massive economic cost of current dementia treatments

Whether terminal lucidity is a biological miracle or a psychological projection of the grieving, it forces us to confront the limits of our knowledge. It suggests that the mind is more resilient, or perhaps more mysterious, than the grey matter it inhabits. We are left to wonder if the essence of a person is truly tied to the integrity of their synapses, or if something else remains when the lights begin to fade.

Key Takeaway

The brain's ability to recover function at the brink of death suggests our understanding of memory is incomplete.

The Agentic Shift

How Muse is redefining the personal AI interface

By Claire Vo · 8 min read

Editor's note: An analysis of why UX design determines the success of the next generation of AI.

Most AI agents feel like a chat box with a brain. They are functional, but they lack a sense of presence. Meta’s Muse is attempting to break this pattern by focusing on the user experience of agency. Instead of just answering questions, Muse manages tasks: calendar deletions, family newsletters, and goal setting. It moves the AI from a tool you talk to, to an agent that acts on your behalf. The difference lies in how the agent communicates its work and how it handles the friction of real-world permissions.

The Importance of Lineage

One of the most significant breakthroughs in Muse is its activity feed. When an agent performs a task, users need to see the 'why' and the 'how'. Most current models operate as a black box; you give a command, and a result appears. Muse provides a step-by-step lineage of tool calls and actions. This transparency builds trust. If the agent deletes a soccer practice from your calendar, you can see exactly which event it targeted and why it thought that was the correct move. This visibility is what separates a toy from a reliable assistant.

The difference between a tool and an agent is the ability to show its work.

Design choices, such as the animated avatar, also play a role in how we perceive these entities. While some might see an avatar as a gimmick, it serves a functional purpose in establishing tone and personality. It makes the interaction feel less like a database query and more like a collaboration. However, the technology still hits walls. Browser-based tasks, such as shopping for specific items, remain hit-or-miss. The agent can book an IMAX ticket with ease, but navigating the specific nuances of a retail site is still a struggle.

What makes a successful AI agent

Transparent task lineage and activity feeds
Robust permission models for real-world actions
A consistent and useful personality/tone
The ability to handle complex, multi-step workflows

The race for the personal agent will not be won by the largest model, but by the best interface. As AI becomes more capable, the bottleneck will be how humans interact with that capability. We don't need more intelligence; we need more usable agency. Muse is a signal that the next era of software will be defined by how well machines can integrate into the messy, unscripted reality of human life.

Key Takeaway

The future of AI belongs to agents that prioritize transparent agency over mere conversational ability.

The Death of the Dashboard

Salesforce and the move toward headless enterprise software

By Stratechery · 7 min read

Editor's note: Why the traditional software interface is becoming obsolete.

For decades, software companies have built moats around their user interfaces. If you knew how to navigate Salesforce or SAP, you were unlikely to switch. The UI was the product. But Salesforce is making a strategic pivot that acknowledges a new reality: the UI is disappearing. As AI agents become the primary way users interact with enterprise data, the traditional dashboard becomes a bottleneck. The goal is no longer to build a better screen, but to build a better engine that can operate without one.

The Rise of Headless Software

This shift toward 'headless' architecture means that the software's value lies in its ability to be called by other systems—specifically, AI agents. In this new model, the user doesn't log into a portal to run a report; an agent queries the backend and delivers the insight directly into the user's workflow. This removes the friction of navigation and allows software to become an invisible part of the operational fabric. It is a high-stakes gamble: Salesforce is essentially abandoning its most visible asset to ensure it remains the brain behind the agents.

The UI is no longer a moat; it is a friction point.

This transition creates a massive challenge for incumbents. If the interface is gone, how do you maintain brand loyalty? How do you charge for value when the user never actually 'sees' your product? The answer lies in data and integration. The winner in the headless era will be the company that owns the most reliable, most accessible data layer. It is a move from being a destination to being a utility.

Consequences of the headless shift

Erosion of traditional UI-based moats
Increased importance of API reliability and speed
A shift in value from 'ease of use' to 'ease of integration'
The transformation of software into an invisible utility

We are entering an era where the most successful software will be the software you never have to touch. For enterprise leaders, this means rethinking how they measure user engagement and how they defend their market position. The dashboard is dying; the engine is everything.

Key Takeaway

In an agent-driven world, the most valuable software is the kind that doesn't require an interface.

The Art of the Imitation

Why we have spent millennia faking marble

By Aeon · 6 min read

Editor's note: A look at the intersection of luxury, scarcity, and human creativity.

Marble has long been the ultimate symbol of permanence, luxury, and divine connection. From the statues of ancient Rome to the grand halls of the Renaissance, its unique patterns and weight have commanded respect. But for as long as humans have prized marble, we have also been trying to fake it. The history of imitation marble is not just a history of cheap alternatives; it is a history of our desire to democratise luxury and our obsession with recreating the patterns of the natural world.

Democratising the Divine

The ability to cast, plaster, and paint imitations of metamorphic rock allowed middle-class households to participate in an aesthetic previously reserved for the elite. Techniques evolved from simple paints to sophisticated composite materials that could mimic the heft and texture of the real thing. This wasn't just about saving money; it was about the human impulse to bring beauty into spaces where it was previously inaccessible. We use imitation to bridge the gap between our aspirations and our reality.

Imitation is not just about deception; it is about the human drive to replicate the sublime.

This process reveals a strange tension in our relationship with nature. We admire the randomness and complexity of natural stone, yet we spend enormous amounts of effort trying to manufacture that very randomness. We want the 'look' of nature without the logistical difficulty of quarrying and transporting massive slabs of rock. In this way, fake marble is a testament to our ability to master and manipulate the aesthetic properties of the world around us.

Drivers of marble imitation

Economic accessibility for non-elites
The desire to replicate natural complexity
Technological advances in plaster and casting
The tension between scarcity and mass production

As we move into an era of digital perfection, the history of fake marble reminds us that our fascination with the 'real' is often driven by our ability to create something that looks just as good. We are constantly competing with the natural world, trying to capture its essence in forms we can control.

Key Takeaway

Our obsession with imitation is a drive to control and democratise the beauty of the natural world.

The Virtue of the Bandwagon

Why fair-weather fandom is a healthy social tool

By Hannah Seo · 5 min read

Editor's note: Challenging the stigma of superficiality in social connection.

There is a certain social hierarchy among sports fans. At the top are the lifelong devotees, those whose identities are inextricably linked to a team's history and failures. At the bottom are the 'fair-weather' fans—those who only show interest when the team is winning. For a long time, this has been viewed as a form of inauthenticity, a shallow way to engage with a culture. But this perspective ignores the psychological and social utility of jumping on a bandwagon.

The Power of Shared Drama

Fandom, at its core, is about collective experience. When a crowd of like-minded people gathers to watch a high-stakes game, they participate in a shared drama. The tension, the racing hearts, and the eventual roar of victory create a sense of awe and social connection. It doesn't matter if you have followed the team for twenty years or twenty minutes; the emotional rush of the moment is real. Fair-weather fandom is simply a way of using social cues to decide where to direct our attention and our joy.

Jumping on bandwagons is a normal and valuable part of life.

We use these cues in almost every aspect of our lives, from fashion to technology. Choosing to participate in a moment of greatness is not a sign of weakness, but a sign of social intelligence. It is an acknowledgment of value. When we join a bandwagon, we are recognizing the excellence of the thing we are following. This shared celebration can actually improve psychological well-being by fostering a sense of belonging and communal excitement.

Benefits of fair-weather fandom

Immediate participation in collective experiences
Social connection through shared emotional highs
Low-barrier entry into community activities
Recognition of excellence and greatness

Instead of guarding the gates of fandom with elitism, we should embrace the influx of new energy. The goal of culture is not to remain pure and exclusive, but to be lived and enjoyed. If a bandwagon provides a window into a shared human experience, then there is no shame in boarding it.

Key Takeaway

Social connection is more important than the depth of your historical knowledge.
