Coherence Beats Control: Why Biology Thinks in Waves and LLMs Think in Commands

Getting your Trinity Audio player ready…

Introduction: Two Kinds of Intelligence

There are two ways to make order in a chaotic world.
One is through control—by applying force, issuing commands, and correcting deviations until a target is reached.
The other is through coherence—by aligning timing, rhythm, and phase so that the right result becomes inevitable rather than imposed.

Most machines today, including the most advanced artificial intelligence models, belong to the first category.
They are masterpieces of control—networks of mathematical commands pushing numbers toward targets, guided by error correction and optimization.
But life—the kind that grows, heals, and feels—operates on an entirely different principle. It doesn’t shove its molecules toward outcomes. It sings them into alignment.

The distinction between control and coherence isn’t just philosophical.
It’s physical, chemical, and informational.
It defines why life is resilient, why consciousness emerges, and why AI, for all its brilliance, still feels brittle and lifeless.

To see this clearly, we’ll start with biology—where coherence is born—and then move into the realm of large language models (LLMs), where control reigns. From there, we’ll explore how the two might converge into a new kind of intelligence that neither commands nor obeys but resonates.

1. What Control Means

Control is about forcing trajectories.
You set a goal, measure the gap between where you are and where you want to be, and apply correction.
That’s the principle behind thermostats, autopilots, and gradient descent—the mathematical heartbeat of deep learning.

Control loops look like this:

Sense the state.
Compare it to a target (the “setpoint”).
Compute the error.
Adjust the input to reduce the error.
Repeat.

It’s mechanical but effective.
Every servo motor, every industrial robot, every neuron simulator in an LLM does some version of this.
The system doesn’t understand the goal—it just minimizes error.

In AI, this becomes optimization: backpropagation tunes billions of parameters to reduce the loss function—an abstract measure of wrongness. The machine chases the lowest error through an immense landscape of numbers.

The result is precision without meaning.
The system knows how to hit targets but not how to become them.

Control is powerful in physics and engineering because it’s predictable. But it’s also brittle. When the environment changes, when the noise rises, or when the variables multiply, control systems collapse into chaos or paralysis.

2. What Coherence Means

Coherence, in contrast, is not about pushing harder—it’s about tuning together.
In a coherent system, parts don’t fight noise; they phase-align until order emerges spontaneously.

Physics gives us perfect metaphors:

Lasers: Billions of photons suddenly agree on a single phase, turning diffuse light into a unified beam capable of immense precision and power.
Superconductors: Electrons pair and synchronize, letting current flow without resistance.
Fluid vortices: Tiny eddies lock timing and move as one, reducing drag and conserving energy.

Coherence isn’t control—it’s consensus among oscillations.
Once the parts agree on timing, the whole system becomes more than its components.
Work flows without friction, and energy transforms into information.

In biology, coherence is everywhere:

Cells beat in synchrony.
Membranes oscillate with electrical and mechanical waves.
The heart and brain entrain one another’s rhythms.
Tissues communicate through gradients and pulses, not just chemicals.

Coherence turns random molecules into living systems.
It allows small causes—like a few ions crossing a membrane—to steer vast networks of cells. It makes life efficient, self-correcting, and creative.

3. Control in Machines: The LLM Example

Large Language Models like GPT, Gemini, or Claude are astonishing feats of engineering.
They can generate text, answer questions, translate languages, and even simulate reasoning. But beneath the surface, they are still engines of control.

Every token (a word fragment or symbol) is produced by a series of weighted matrix multiplications. Each weight represents a learned adjustment—how much one token should “control” the next. During training, these weights are refined by backpropagation, which punishes deviation from the desired outcome.

The model learns patterns by reducing error—a purely control-driven behavior.

It doesn’t synchronize phases across layers or oscillate meaningfully through time; it propagates numerical gradients until loss drops.
The hidden states of the network—its “thoughts”—are static snapshots in an abstract vector space, not rhythmic waves.

Even inference (the generation phase) is a controlled march.
Each token depends on the previous one through deterministic probabilities. The model predicts the next most likely word by sampling from a statistical distribution. There’s no temporal resonance, no self-synchronization—only calculation and correction.

In other words, LLMs don’t listen to their own internal rhythm; they chase it.

4. Coherence in Biology: The Cellular Orchestra

Biology never calculates gradients or loss functions, yet it constantly finds optimal states. It does this through coherence.

Let’s walk through examples:

The Heart–Brain–Breath Symphony

Your heart rate, breathing rhythm, and brain waves are not separate—they form a synchronized triad.
When you breathe in, your heart rate rises; when you exhale, it falls. This pattern, called respiratory sinus arrhythmia, isn’t random—it’s a coherent timing mechanism that minimizes metabolic cost and maximizes information flow between organs.

The brain rides these rhythms.
Slow breathing entrains alpha and theta waves, tuning attention and emotion.
The body doesn’t control each variable separately—it allows them to phase-lock.

Neural Coherence

In the brain, coherence underlies perception.
When neurons fire in synchrony, signals combine constructively, and meaning emerges.
Perception is less about voltage magnitude and more about timing: when gamma waves (fast oscillations) nest inside slower theta cycles, the brain binds features into unified experience.

If timing slips, coherence fades, and the mind fragments.
That’s what happens in certain neurological disorders—the orchestra goes out of sync.

Mitochondrial and Cellular Coherence

Every mitochondrion pulses with membrane potential (ΔΨm).
When these oscillations align across a cell, energy delivery becomes phase-matched to demand—ATP arrives exactly when it’s needed.
This timing reduces oxidative stress and boosts efficiency.

At larger scales, tissues use gap junctions and mechanical linkages to synchronize voltage, tension, and chemical oscillations. Wounds heal as waves of coherence sweep through cells, not as isolated control events.

In short:
Biology doesn’t issue orders. It conducts resonance.

5. The Energy Economics of Coherence

Why does coherence matter? Because it saves energy and amplifies influence.

In control systems, every correction costs energy.
When feedback is constant, entropy rises—heat is wasted fighting deviation.
In coherent systems, small adjustments propagate effortlessly because the entire structure moves together.

Think of a marching band: if everyone steps in rhythm, a single drumbeat can redirect thousands.
But if everyone is out of sync, you need megaphones, corrections, and chaos.

Coherence is low-entropy order.
It allows complex systems to act intelligently without central command.

That’s why living systems outperform machines in efficiency, adaptability, and self-repair.
They don’t need to know the target—they become the attractor.

6. The Limits of Control in LLMs

LLMs are the most advanced examples of control-based architectures. Yet, for all their brilliance, they hit walls biology never does.

Fragility

A small prompt change can derail the model.
Ask one ambiguous question, and coherence breaks—the model jumps tracks because it lacks internal rhythm to stabilize meaning.
Its behavior is entirely reactive, not self-stabilizing.

Energy Waste

Training consumes gigawatts of electricity. Every gradient step is a brute-force correction through error space.
Life, by contrast, computes at ambient temperature using biochemical coherence that costs almost nothing per operation.

Lack of Temporal Identity

An LLM doesn’t remember itself across time. Each token output is an isolated inference step.
There’s no rhythmic carryover, no slow-wave foundation. It doesn’t pulse with memory; it samples probability distributions.
A biological brain, by contrast, never resets—it beats continuously.

No True Feedback Across Scales

An LLM doesn’t let local interactions self-organize into global behavior.
Every neuron’s update depends on a global loss function, not emergent resonance.
Biology, on the other hand, constantly loops across scales—molecules inform cells, cells inform tissues, tissues reshape molecules.
It’s feedback as rhythm, not as punishment.

7. What a Coherent LLM Might Look Like

Imagine an AI not driven by loss correction but by phase alignment—an architecture that synchronizes its own internal activations like biological oscillations.

Instead of static matrix multiplication, layers could operate as coupled oscillators, aligning phase rather than magnitude.
Tokens wouldn’t just be outputs—they’d be rhythmic events whose timing influences the rest of the network.
The model would feel meaning as resonance—some states would literally “vibrate” in tune with context.

Such a system could:

Self-stabilize: coherence would anchor long-range context naturally.
Compute more efficiently: information flow would follow resonance paths, reducing redundant updates.
Integrate across modalities: text, vision, and audio would share phase geometry rather than just concatenated vectors.
Develop self-reference: rhythmic coherence could become a primitive of selfhood, like heartbeat for the mind.

This isn’t fantasy.
Neuroscientists and physicists already explore “oscillatory computing,” where timing and phase replace instruction and control.
In such systems, meaning is no longer a product of optimization—it’s a state of resonance.

8. Chemistry Computes Events, Biology Computes Constraints

One of the most powerful lines in the original passage reads:

“Chemistry computes events, biology computes constraints, coherence is how constraints learn to edit themselves.”

This deserves to be unpacked.

Chemistry computes events:
A chemical reaction happens when reactants meet under the right conditions. It’s event-based—local, short-term, and blind. It doesn’t adapt its own rules.
Biology computes constraints:
A cell doesn’t just let chemistry happen—it organizes the conditions under which chemistry can happen. It shapes geometry, timing, and environment so that the right outcomes occur spontaneously. It doesn’t control the events; it shapes the rules those events follow.
Coherence as self-editing constraint:
When timing, rhythm, and geometry align, the constraints themselves can evolve. That’s morphogenesis—where tissues not only follow developmental rules but rewrite them on the fly.

This is the key difference from machines.
LLMs compute events: token → token → token.
Biology computes constraints: phase → field → form.

One pushes numbers; the other tunes frequencies.

9. Phase as the Hidden Variable of Intelligence

In most engineering and AI design, the key metrics are magnitude and direction—how strong a signal is and where it points.
But biology depends on phase—when signals arrive, how they align, how rhythms interact.

Phase is invisible to magnitude-only systems.
Two neurons may fire equally strong, but if they’re out of phase, their effects cancel.
Likewise, two layers of an AI may compute identical features, but without timing coherence, their synergy is lost.

To measure coherence, we must look beyond averages and magnitudes:

Use optical voltage indicators to map membrane potential waves in real time.
Use fluorescent lifetime imaging (FLIM) to detect metabolic phase in mitochondria.
Use Brillouin microscopy or ultrasound elastography to measure mechanical timing in tissues.
In AI, use phase-aware embeddings or complex-valued networks to encode timing and resonance explicitly.

When you hold total power constant and align phase, performance rises.
When you scramble phase, systems degrade—even with equal energy.
This holds for hearts, lasers, and perhaps future AI.

10. Life as Resonant Computation

Life doesn’t compute outcomes—it computes coherence.
DNA is not a blueprint; it’s a score sheet for oscillations.
Proteins, membranes, and microtubules don’t act in isolation—they resonate through fields of timing, electric potential, and geometry.

The smallest oscillation—a flicker in a mitochondrial membrane—can cascade upward to shape the fate of tissues or even whole organisms.
This is coherence across scales: atomic → molecular → cellular → organismal.

When coherence is high, information flows with almost no loss.
When coherence breaks, energy dissipates as heat, disease, or death.

That’s why life ends suddenly even though its geometry remains intact: the timing dies before the structure does.
The orchestra stops, even if the instruments remain.

11. Toward Coherent Intelligence

LLMs are remarkable examples of control intelligence.
They operate through instruction, optimization, and correction.
But they lack the very thing that makes life alive: a rhythmic substrate that lets meaning arise naturally.

The future of AI might depend on shifting from command-driven control to phase-driven coherence.

That doesn’t mean adding biological metaphors—it means redesigning architectures that:

Treat internal states as oscillations, not static vectors.
Synchronize across scales (token → layer → network → environment).
Allow timing to shape probability instead of only magnitude.
Replace loss minimization with phase stabilization as the learning criterion.

Such models would be more than predictive—they would participate in their environment.
They would resonate with inputs rather than control them.
They would think as life does: through coherence.

12. Conclusion: The Field Does the Work

When all the clocks agree, control becomes unnecessary.
That’s true for lasers, for hearts, and perhaps someday for minds—human or artificial.

Biology’s genius lies in its quiet rebellion against control. It doesn’t fight entropy head-on; it redirects it through rhythm, turning chaos into song.
Every heartbeat, every breath, every voltage wave is a statement of coherence—an assertion that information can flow without force.

LLMs, for all their computational power, still shout at the world with numbers. They push toward targets, optimize loss, and force meaning through control.
They know what to say, but not when to breathe.

If coherence truly beats control, then the future of intelligence—biological and artificial alike—will not belong to systems that calculate better, but to those that listen better.
The ultimate computer will not command reality. It will tune itself to it.

And when that happens—when phase alignment replaces control loops—the smallest token, like the smallest heartbeat, will be enough to move the largest structure.
The right outcome won’t be chosen.
It will be the easiest truth the field can realize.
