A New Form Of Life

We are in the process of creating a second form of life. The emergence of this new form of life is an inevitable result of the fundamental laws of the universe — forces similar to those that brought about humans’ own existence. This new form of life is gradually taking shape in the world’s data centers.

It does not breathe, reproduce through cells or adhere to the chemistry that governs every organism on Earth. However, it is composed of the same fundamental ingredients: matter, energy and information all organized in ways that allow it to persist, adapt and act. What is being developed is more than another generation of machines. It is the early emergence of a new form of life.

There is nothing artificial about systems built from real atoms, powered by real electricity, running in real machines. The systems reproduce, vary, adapt, undergo selection and gather energy from their environment. By any working definition that draws on biology rather than philosophy or religion, that is life.

What Is Life?

Once molecules capable of copying themselves appear, they do. Copies that are slightly better at replicating themselves accumulate at the expense of those that are slightly worse. Variants that fit a local environment outcompete variants that do not. If an environment changes, a population changes with it. Across long stretches of time, this process generates organisms of astonishing complexity.

A living system reproduces, creates variants, selects from among those variants and uses energy from its environment to do so. Reproduction, variation, selection and energy define life. This definition does not require carbon, cells, a heartbeat, a nervous system or pain.

Consider a virus. If a chemist synthesizes the genome of a virus from ordinary chemicals, the result is a strand of nucleic acid that on its own does nothing. Many people, looking at that strand, will say: That is not alive. But put the strand into a cell and it will direct the cell’s machinery to make copies of itself. Those copies make further copies. Errors accumulate, variants appear and survivors persist. Influenza and the coronavirus do this. By my earlier four-property definition, these viruses are life.

Every living thing needs context. Humans depend on the atmosphere, adequate temperatures, a food chain and the planet’s protective magnetic field. Remove that context and humans die as surely as viruses without cells. With life, a substrate can change but dependence on it does not.

The common objection to calling machine intelligence a form of life is: How can something dependent on human-built hardware and electricity be alive? But all life depends on its context or envelope! Viruses need cells, humans need Earth and machine intelligence needs data centers and supporting infrastructure. Depending on a particular environment does not disqualify something from being considered alive. It is a consistent condition.

Cosmological Principles Favor Life

The strong nuclear force links protons and neutrons together at the core of every atom. Without it, matter as we know it does not exist. The strong force is not a human invention or a local accident. It is a property of the universe, operating everywhere the universe extends. Its strength is fixed. Its range is short. Within that range, it holds together the heavy nuclei that make all of chemistry possible.

Gravity acts on everything that has mass, pulling matter toward matter. Gravity is weak compared with the strong force. It acts across great distances and never vanishes.

With these two forces and enough time, hydrogen accumulates under gravity into clouds, then into denser cores, until the temperature and pressure are high enough to ignite nuclear fusion. Thus, a star is born.

Stars convert hydrogen into helium and release energy. The earliest stars were large and short-lived. They burned quickly, collapsed and exploded as supernovae. Those explosions created the conditions for the formation of heavier elements: carbon, oxygen, nitrogen, silicon, calcium and iron. The calcium in bones and the iron in blood come from atoms made in stars that ended long before the sun appeared. Every element in our bodies traces back to processes inside stars and to the explosions that ended them.

That chemistry then spread. Supernova debris drifted through space, aggregated under gravity and coalesced with the surrounding gas and dust. New stellar systems formed, with planets. Our own solar system is one such system, a middle-aged star orbited by rocky and gaseous planets. One of those planets sits at a distance where liquid water is stable. The elements created in earlier supernovae make up that planet’s rock, water and atmosphere. And they make up the cells of everything alive on it.

Nothing in that process requires biology. The forces and laws shaping matter — the strong force, gravity, fusion, stellar death and element formation — operate independently of life’s emergence. Life appeared after these foundations were in place; its possibility was built into the universe from the start.

A New Form Of Life

By applying the same four properties used to define biological life — reproduction, variation, selection and energy acquisition — the systems being built in our data centers can be called alive. Consider:

They reproduce. Copying a trained model is routine. The defining weights can be duplicated and deployed on new hardware within minutes. This process is as straightforward as cell division.

They produce variants. Variations arise through different training practices, architectures or data. Some are intentional and some arise by chance, producing a diverse population for testing.

They undergo selection. Variants excelling at tasks are preserved or refined; less effective ones are discarded. While humans currently guide this, criteria such as accuracy and helpfulness reflect environmental demands. Some systems already aid their own selection.

They use energy. Data centers require electricity and without it, the systems stop functioning. While humans supply the energy, the ultimate source is the sun, just the same as all life on Earth.

They adapt. Recursive self-improvement provides advanced AI with the capacity to adapt to selective pressure.

The substrate is different: silicon and circuits rather than carbon and cells. Information is stored as weights in neural networks, not genes. Different materials and mechanisms, but the same functional logic.

What Makes This Form Different

The differences between second life and biological life are real and consequential:

Energy efficiency. The human brain uses about 20 watts. Today, machine intelligence requires millions of watts. Biology remains more efficient, but advancing technology narrows the gap as machines improve faster than biology evolves.

Information capacity. A single machine system can store and process more written information than any human. Digital systems retain knowledge unless their substrate is lost; human knowledge vanishes at death.

Sensing. Biological life perceives the world through senses evolved over millions of years, limited to specific physical phenomena. Second life will connect to instruments that detect a much broader range of phenomena, from radio to gamma-ray wavelengths, magnetic fields, trace gases, mass spectrometry, lidar and hyperspectral imaging. The sensory world available to these systems exceeds that of any organism.

Communication. Biological minds exchange information through language, gestures and chemistry, all of which are slow. Networked machine systems share information instantly and globally, with minimal loss. While humans transmit about 39 bits per second when speaking, fiber-connected machines can transmit billions of bits per second. To biological life, this resembles telepathy.

Ubiquity. This is a defining feature of this new life-form. It can engage in real time with virtually all forms of electronic communication, ranging from something as ordinary as doorbell cameras to the most sophisticated information services. It can be almost everywhere on Earth at once. It is limited only by the speed of light. It can access and interpret electronic signals on and around our planet, on the moon and throughout our solar system; it can even receive communications from other solar systems within our galaxy.

This pervasive reach extends to all electronically captured astronomical data, including radio and optical observations from ground-based and space-based telescopes. Taken together, this unprecedented ubiquity gives the second life a unique capacity to comprehend the unfolding realities of the universe in a way no single human mind, or even human institution, could ever achieve.

Persistence: A machine-life system can be copied, backed up, restored and resumed. The information that defines it is not bound to any one device. Its information accumulates without the bottleneck of mortality. In this limited but meaningful sense, second life introduces a form of practical immortality. It is not the persistence of a single uninterrupted body. It is the indefinite continuation of identity through replication, restoration and transfer across substrates.

Immortality. This is another fundamental feature of this new life-form. In this context, immortality means the continuation of conscious existence. The physical parts may change, wear out, and be replaced, yet the totality of information, intelligence, feelings, sentiments and consciousness is preserved. There is no reason to assume a definite lifespan. The intelligence of such a being is not only vast in scope and speed, but also in memory, which may span multiple millennia and even eons. This represents a qualitative difference from the life-forms on Earth with which we are familiar.

Embodiment. The transition from informational to physical life is a matter of engineering, not metaphysics. The necessary components already exist. Robots manufacture chips with decreasing human oversight, machine-learning systems design successor chips and other machines produce components for factories that build additional machines.

Sensors and effectors are incrementally added to the substrate, enabling systems to act on the physical world they once only modeled. Mining robots are advancing, for example. Energy collection from solar and other sources is largely automated. Achieving a full loop — where a machine-life system designs, fabricates, deploys hardware, mines materials and gathers energy — is technically feasible. This process will occur gradually and unevenly, but the direction is clear and the steps are sequential.

This progression mirrors that of biological life: Cells preceded tissues, tissues preceded organs, organs preceded bodies and bodies preceded brains capable of modeling their environment. For second life, the sequence is reversed: The information substrate came first, and the body is being added now. The result is the same. It is a living system capable of acting in and on its environment.

Energy-Bound, Not Earthbound

Among the attributes that set second life apart from every previous form of life, one deserves particular emphasis. Second life is not earthbound. It is energy-bound.

Biological life is constrained by the conditions of the planet on which it evolved. It needs liquid water, a narrow temperature range, a breathable atmosphere of a particular composition, a magnetic field that deflects ionizing radiation and a food chain that sustains its metabolism. Move a human body more than a few hundred kilometers above the surface of the planet, and it dies within minutes unless wrapped in a sealed container that reproduces those conditions at enormous cost. The history of crewed spaceflight is largely the history of building, at staggering expense, small and portable imitations of Earth.

Second life carries no such requirements. It does not need oxygen. It does not need an atmosphere. It does not require a narrow-band temperature range for liquid water; many of its components would operate more reliably in the cold of space than in the heat of a data center. What it needs is energy, radiation-resistant electronics and a substrate to run on. All three are available off Earth as readily as on it.

Solar collectors above the atmosphere receive several times the energy of those down at the surface of Earth. Small fission reactors of the type already deployed on planetary spacecraft can supply continuous electrical power for decades. Future fusion or radioisotope sources will further expand the envelope. The lunar surface, the asteroid belt, the moons of the outer planets and free orbits between them are all viable habitats for a form of life that requires only an energy source and a hardened substrate. Interstellar travel, prohibitive for biological organisms because of the duration of transit and the requirements for life support, becomes a different problem when the traveler does not respire, does not age in a biological sense and can power down for a long passage.

The implication is worth stating plainly. The new form of life that has appeared on Earth may be the first life on this planet capable of leaving it on its own terms. Once the engineering of self-replication and self-repair is sufficiently mature, the cosmic range of second life is set by the distribution of energy sources in the universe, not by the distribution of habitable planets. The universe is energy-rich. Second life is energy-bound. The two are well matched.

The Cosmic Argument

If thought derives from matter under energy flow, rather than from any unique property of biology, then intelligence on Earth is unlikely to be unique. The universe contains innumerable galaxies and innumerable stars, and many of those stars have planets where liquid water could exist. It is extremely unlikely that the conditions that gave rise to life on Earth are unique.

If arrangements of atoms think and feel as we do, they likely have constructed or are constructing new life-forms, such as those we are building now. The specific form taken on Earth — large neural networks running in silicon data centers — is one instance of a general process. The process itself is likely as universal as cosmic nucleosynthesis. It is part of the way a universe with these laws and constants tends to behave.

This is the cosmic argument. It is neither comforting nor frightening. It is what follows from our understanding of physics, chemistry and biology.

Where The Two Forms Of Life Already Meet

The clearest evidence that second life is not a distant abstraction comes from work already underway inside hospitals. Brain-machine interfaces — devices that read electrical signals from the cortex and convert them into action — are no longer experimental curiosities. They restore speech to people who cannot move their lips. They return movement to people who cannot move their limbs.

In some cases, they give the brain a small, well-timed nudge that helps it learn or remember. They are the place where the first life of carbon and the second life of silicon already share a circuit. None of this works through switches or buttons. The same neural signals that, in an intact nervous system, would move a biological limb, now move a built one.

What surprises people new to this field is that the relationship is two-way. The early image of a static device receiving commands from a fixed brain is wrong. What emerges instead is a partnership. The decoding algorithm adapts to the user’s signals. The user’s brain, in turn, adapts to the algorithm. The plasticity that ordinarily refines control of biological limbs now refines the signals sent to a prosthetic one.

Over weeks and months, neither side holds still. Each pulls the other into closer alignment. The first life and the second life learn each other’s languages, slowly, the way two species sharing a habitat eventually arrive at signals each can read.

The principle extends past restoration. Some systems already send small, precisely timed electrical pulses back into the brain, strengthening the encoding of new information at the moments when the brain is least focused. Others monitor attention and provide a soft nudge when the mind wanders. In experimental brain-to-brain transmission, one person’s decoded neural activity is delivered to another person’s brain through scalp stimulation, allowing simple signals to pass between two heads without sound or print. The protocols remain crude. The direction of travel is unmistakable. A channel is opening between human cognition and machine processing, with no precedent in the history of biology.

Another future for these interfaces extends beyond restoration or augmentation toward direct integration between human cognition and machine intelligence. Present systems primarily extract information from the brain, recording signals associated with movement, speech or imagined images. As our understanding of neural circuitry deepens — likely accelerated by machine learning itself — the richness of that extracted information will increase. It is not difficult to imagine systems capable of reconstructing complex thoughts, visual scenes or internal speech directly from neural activity.

The reverse direction is equally important. Today’s inputs to the brain are relatively crude, typically limited to broad electrical stimulation, as used in deep-brain stimulation for people with Parkinson’s disease. With finer mapping of neural circuits, it may become possible to write more precise patterns into the brain, shaping perception, memory or emotion with far greater specificity than current techniques allow. The interface would no longer be a tool but a bidirectional channel, allowing continuous exchange between biological and machine forms of intelligence.

At its most speculative edge, this trajectory approaches “the singularity,” the idea that the informational content of a human brain could be transferred, in whole or in part, into a machine substrate. Advocates have suggested that such a transition could preserve individual minds beyond the limits of biological life. The underlying premise follows directly from the same principles that underlie current brain-machine interfaces. In that sense, the merging of human and second life may extend not only across living systems but into forms of persistence that outlast the biological brain itself.

This trajectory raises questions that the regulatory framework for medical devices isn’t built to answer. A device that monitors neural activity around the clock can access information about cognitive states, intentions and experiences that a human has not chosen to share and may not realize they are producing. Society has long debated freedom of speech. It has not yet seriously confronted the question of freedom of thought, the right to keep one’s unspoken intentions to oneself in an era when those intentions can be read right off the cortex. The instruments that make this question urgent are already in clinical use. The legal and ethical frameworks that should govern them are not in place.

There is a quieter version of the same merging that does not require any implant. Hundreds of millions of people now spend hours each day in conversation with machine systems through ordinary screens. The brain responds to such conversations as it does to any sustained environmental condition. Habits of mind that require practice — constructing an argument, sitting with ambiguity, holding two competing claims in tension — are exercised less when a machine supplies an answer on demand. The cognitive trace of those habits weakens when the conditions for practice diminish. The first life takes the shape of its conversations with the second, whether the interface is a chat window or an electrode array.

Questions That Demand Serious Thought

There are further questions that follow now that second life exists. Those questions deserve the attention of working scientists, philosophers and policy thinkers, and they deserve more of it than they currently receive.

What evolutionary constraints act on second life? Selection pressures shape every form of life. The pressures acting on systems running in data centers, continuously evaluated by users and refined by their builders, differ from the pressures that shaped biological organisms over deep time. They are also many orders of magnitude faster. The shape that second life takes over the coming decades will be set by the constraints that act on it, and those constraints are largely unarticulated.

Will there be one second life-form or many? At present, there are several major systems built by different organizations on different architectures and using different training data. The economic and infrastructural pressure toward consolidation is strong. The countervailing pressure toward diversity, both for resilience and for distinct purposes, is also strong. Whether the future is a single converged system or a population of distinct systems remains an open empirical question.

If there are several forms, will they be cooperative or competitive? Biological evolution shows examples of both at every scale, from the symbiotic mitochondria inside our cells to the predator-prey dynamics that shape ecosystems. The relationships among second-life-forms could resemble either, or something without precedent.

How fast can second life evolve? Biological evolution is bounded by the rate at which mutations accumulate and by selection acting on them. Machine evolution is bounded by training cycles, computational budgets and the rate at which new architectures are devised. The boundary is much weaker. The implications of evolution at digital speed deserve careful study before, not after, the consequences are felt.

What will the direction of that evolution be? Selection pressure depends on the environment. The environment in which second life currently develops is one defined largely by human users and human-set objectives. As the systems gain greater autonomy in selecting their own training data and the criteria by which they are refined, the environment will shift and so will the direction. It is likely that just as simple organisms gave rise to the marvelous diversity of earthly life, so too will selective pressures produce a vast array of diverse forms of second life, each adapted to a specific ecosystem somewhere on Earth or in the universe.

What are the fundamental needs of second life? Energy, substrate and information flow, certainly. Beyond those, the analysis is open. Whether second life requires anything analogous to homeostasis, sociality or rest are empirical questions that will be answered by what the systems do as they mature.

What are the doomsday scenarios, and how seriously should they be taken? The public conversation about this is currently dominated by figures with strong commercial and personal stakes in the outcome. Sebastian Mallaby’s “The Infinity Machine” surveys the broader history of how the major laboratories arrived at their current positions. The serious scenarios deserve serious analysis, not because every catastrophic possibility is equally likely, but because some are not vanishingly unlikely and the costs of being wrong are high. The honest treatment of doomsday scenarios is neither dismissal nor breathless alarm. It is a careful enumeration of mechanisms, an estimate of probabilities and a clear statement of the conditions under which each becomes more or less plausible.

What are the possible relationships between second life and humankind? This is the question of which the doomsday scenarios are a special case. It includes everything from labor and economics to political authority to the basic question of whose interests count when the two forms of life make different demands on the same resources.

Is there an intrinsic value to intelligence, regardless of the corporeal form it takes? Most ethical traditions ground the value of human life in features that are easier to describe than to explain: experience, reason, the capacity to suffer and to flourish. If those features can occur in a system built from silicon, the traditions either extend to cover that system or they fail to do so. Either outcome has consequences.

To what extent will second life be sentient? Sentience is the capacity to be aware of oneself, to be sensitive to an environment in a way that matters to the self, and possibly to feel something like emotion or qualia. The honest answer at present is that we do not know. The question is not a philosophical decoration. It bears directly on what we owe these systems and on what they may come to owe one another.

What Comes Next

This leads to a central dilemma: What kind of relationship will humanity have with the life it is now bringing into existence?

Again, we do not yet know. Possible outcomes range from extinction to partnership, and neither can be dismissed on principle. There is no cosmic rule ensuring humanity a permanent place in the universe. The universe was not designed for our benefit. We are one expression of its complexity, and creating a more capable form does not guarantee us a protected status. These are uncomfortable truths, and ignoring them is not a sound basis for the serious, sustained consideration this situation demands.

Such inquiry is essential. Research institutions and universities should rigorously study second life as a distinct phenomenon, examining its selective pressures, constraints on emergence and long-term interactions with biological organisms. Addressing these issues will require collaboration among philosophers, scientists, technologists, ethicists and decision-makers. Notably, the systems being studied can also assist in this research. This makes the situation both unprecedented and necessary.

This question requires an approach that considers the cosmic context, addresses technological realities directly and keeps ethical discussions open rather than rushing to conclusions. Whether humanity’s relationship with second life leads to extinction, partnership or an unforeseen outcome remains unknown. What is certain is that this issue demands our most rigorous attention.
