Cybernetics: Learning to Steer a Human Life

The art of steering

Beyond machines

Cybernetics is not simply another word for robotics, artificial intelligence, or the merging of people with machines. It is a field concerned with communication, regulation, and feedback across systems—whether those systems are mechanical, biological, or social. Norbert Wiener helped establish its modern foundations with his 1948 book, Cybernetics: Or Control and Communication in the Animal and the Machine.

The word traces back to the Greek idea of a steersman: someone who guides a vessel. That image captures something important. A steersman does not control the wind or command the sea. They observe the vessel’s direction and adjust their actions in response to changing conditions. I find this a useful metaphor for a human life.

We cannot arrange every circumstance in advance. Other people have their own intentions. Our responsibilities change. The destination we once considered desirable may no longer fit the person we are becoming. Steering, then, is not the same as forcing everything to follow a rigid plan. It means remaining attentive enough to make meaningful adjustments. The question is not, “How do I eliminate uncertainty?” It is, “How do I remain capable of responding to it?”

Feedback and adjustment

Closing the loop

A central idea in cybernetics is feedback: information about the consequences of an action returns to influence what happens next. Consider a thermostat controlling a heater. It measures the temperature, responds when the room becomes too cold, and changes its operation as the temperature changes. Its actions affect the very conditions it measures.

The human body also contains feedback mechanisms. Temperature regulation, for example, involves detecting changes and activating responses such as sweating to help counter excessive heat. This is an example of negative feedback: “negative” describes a response that counteracts a deviation, not something harmful or undesirable. For me, the important insight is that an instruction alone is not enough. A system also needs some way to discover what its actions are producing.

Imagine deciding to spend more time on a meaningful project. You create a schedule and begin working. A month later, you review what happened. Perhaps the schedule was unrealistic. Perhaps interruptions were frequent. Perhaps the project itself no longer feels worthwhile. That review gives you an opportunity to change something: the schedule, the environment, the scope, or even the goal.

Without that return to experience, the plan remains an instruction issued by a past version of yourself.

This is also why collecting data is not, by itself, the same as creating a useful feedback loop. A record becomes part of the loop when someone uses it to reconsider an action—and then observes what follows. A dashboard may show what happened. The more interesting question is what that understanding makes possible.

Memory in practice

From journal to pattern

This is where I see a connection between cybernetics and journaling. A journal can preserve more than an account of events. It can preserve the reasoning surrounding them: what I believed, what I expected, what I feared, and why a particular decision seemed sensible at the time. When I return to that record, I can ask a different set of questions. Did the outcome resemble what I expected? What did I overlook? Was I solving the problem I thought I was solving? Would I make the same decision with what I know now?

Consider a hypothetical pattern: repeatedly beginning projects and leaving them unfinished. One interpretation might be, “I lack discipline.” But a record could invite other explanations. Were the projects larger than anticipated? Did competing obligations emerge? Was there a clear next step? Was the original motivation genuinely mine? The purpose would not be to use data to deliver a harsher judgment. It would be to create room for a more accurate question.

That is the kind of self-knowledge I find valuable: not a permanent label, but an understanding that can guide a different response. A journal becomes especially useful when it helps experience influence the next decision. Not every cybernetic system needs a long-term memory. But for the kind of personal system I want to build—one concerned with continuity across months and years—a meaningful record is central. It gives the present self something to examine besides the story that happens to feel convincing today.

Augmentation beyond hardware

The cybernetic suit

There is a physical side to human augmentation, and it deserves its place in this conversation. Researchers have demonstrated systems that use artificial intelligence to decode movement intentions from peripheral nerve recordings and translate them into control of a prosthetic hand. This is a concrete example of biological signals and engineered systems working together. But I am also interested in a complementary kind of augmentation: support for memory, context, and decision-making.

Imagine a “suit” made not primarily of metal, but of useful connections. It could help you return to the reasoning behind an important decision. It could bring together records belonging to the same project. It could help you examine whether your actual commitments reflect your stated priorities. It could preserve an explanation that would otherwise become separated from the event it explains. This is a metaphor for cognitive support, not a claim that a database is equivalent to a brain.

The point is not to replace thought with a system that does the living for us. It is to imagine tools that help us bring more of the relevant context into our own thinking. I would judge such a system less by how much information it contains than by whether it helps a person act with greater understanding.

A system for human agency

Cybernetics at Vitalog

This is why I think of Vitalog as a cybernetics company rather than simply a place to build another application. The ambition is to connect information technology, sensing, and eventually more advanced cybernetic systems around a human purpose: helping people preserve what matters, understand their circumstances, and extend their capabilities.

Within that vision, Matrix Blackbox is intended to provide a sensing connection to the physical world, while XB Lifelog is intended to help record, connect, and interpret information in the context of a person’s life. The underlying direction is:

That final step matters. Without observing the result, we would not know whether an intervention helped, whether an interpretation was mistaken, or whether a goal needed reconsideration. Suppose someone wants to protect time for a project they consider meaningful. In the system I envision, they could bring together their intentions, relevant commitments, progress notes, and reflections. They could compare what they hoped to do with what actually happened, choose a practical adjustment, and review its effect.

The value would not lie in producing a score for that person. It would lie in helping them see their situation clearly enough to make a choice. This remains a direction for development, not a claim that every part of the envisioned system is already complete. I want the foundation to be useful even before the more ambitious possibilities arrive. Preserving the context of a decision, making an important record easier to find, or helping someone recognise a recurring obstacle would already be meaningful steps.

The limits of assistance

AI should assist, not define

Artificial intelligence and cybernetics overlap, but they are not interchangeable. AI can supply capabilities within a system, while a cybernetic perspective examines the relationships among goals, information, actions, and feedback. Adding intelligence to one component does not remove the need to understand the larger loop in which it operates. In the Vitalog vision, I see AI as a possible participant in that loop—not as the final authority over a person’s life.

An assistant might help organise records, suggest connections worth examining, or ask a question that makes a decision easier to understand. But I would want its interpretations to remain open to challenge. A person should be able to ask: What information led to this suggestion? What context is missing? Is this something I actually said, or an inference the system made? Can I correct it? There is a substantial difference between offering, “These entries may be connected,” and declaring, “This is who you are.”

I want technology that supports the first kind of conversation. A personal record should leave room for contradiction, growth, and changing circumstances. Someone should not have to spend their future arguing with an automated interpretation of their past.

The system should help us reconsider our stories, not imprison us inside them.

Choice and control

Who chooses the destination?

The word control deserves care whenever we discuss cybernetics. Helping someone regulate their own actions is very different from designing a system to regulate them for somebody else’s benefit. That distinction is fundamental to the kind of technology I want Vitalog to become. Who decides what the system is trying to achieve? Who chooses what gets recorded? Who can inspect the information? Who can change the recommendations, disconnect a sensor, or stop participating?

These should be design questions from the beginning, not uncomfortable details postponed until the technology is powerful. For me, a personal cybernetic system should be accountable to the person it serves. Participation should be meaningful and voluntary. Records should be correctable. People should have practical control over access, retention, and deletion. Information involving others should be handled with respect for their privacy, too. There must also be room not to measure.

I do not want to turn every friendship into an engagement metric or every quiet afternoon into evidence of insufficient productivity. A conversation can matter without being recorded. Rest does not need to justify itself through a performance score.

The ability to measure something does not establish that measuring it is worthwhile.

A system might help us pursue a destination more efficiently. It cannot settle the ethical question of whether that destination deserves pursuit. That responsibility remains ours.

Ambition and evidence

Lives worth extending

Vitalog’s longer-term ambition includes radical life extension and the expansion of human potential. I see cybernetics as part of the framework through which to explore that ambition: how might better connections among observation, understanding, and action support a person over time? But an ambition is not evidence of an achieved outcome.

A lifelog should not be presented as proof of increased lifespan. Preserving someone’s records is not, by itself, a demonstration that their consciousness has been preserved. Claims about health or longevity would need their own evidence, not simply an appealing analogy between people and machines. For me, the ambition is still worth pursuing with that distinction intact.

I want technology to help alleviate suffering and expand what people are able to do. I want us to explore whether some boundaries we currently accept can be changed, while remaining honest about what has and has not been demonstrated. And I do not think the value of a longer life can be separated from the experience of living it. The future I care about includes more opportunity to love, learn, create, recover, and contribute—not merely more time to be monitored.

A practice of becoming

From knowing to steering

Temet nosce. Know thyself. For me, cybernetics adds a practical question to that invitation: What will you do with what you discover? Self-knowledge can remain an interesting description, or it can become part of a continuing practice. We notice something. We preserve enough context to examine it. We choose a response. We remain willing to learn from what happens next.

That does not make a human life simple or entirely controllable. Nor should it. What it offers is a way to participate more consciously in our own becoming. That is the possibility I want to explore through Vitalog: technology that helps us remember without defining us, understand without judging us, and act without taking our choices away. Not a machine that takes over the journey.

A better set of instruments—and a clearer view from the helm.
