Scientists have grown human brain cells on a silicon chip and taught them to play video games. The technology is real, the potential is significant, and the questions it raises about consciousness, identity, and the limits of human knowledge are ones Scripture was already prepared to answer.

Melbourne-based biotech company Cortical Labs has taught living human brain cells grown on a silicon chip to play the video games Pong and DOOM, creating what it calls the world’s first commercially available biological computer, a device that keeps 200,000 living human neurons alive in a sealed life-support chamber while allowing software developers to interact with them remotely through a Python API.

This matters because the technology is not science fiction: it opens genuine pathways toward modeling neurological diseases, developing energy-efficient computing, and understanding human intelligence, while simultaneously crossing philosophical and ethical boundaries about consciousness, identity, and human dignity that our civilization has not yet developed the wisdom to navigate.

Scripture identifies the increase of knowledge as a defining marker of the final generation, affirms human beings as uniquely made in the image of God in ways that no technology can replicate or render irrelevant, and warns that knowledge without the fear of God does not produce flourishing but confusion, as humanity attempts to transcend the limits its Creator built into its nature for reasons that wisdom alone can perceive.

The technology is real. The scientific potential is significant. And the questions it raises about intelligence, consciousness, identity, and the boundaries of human knowledge are questions our civilization is only beginning to confront.

This is not a story about panic. It is a story about power. About knowledge increasing faster than wisdom. And about what happens when a civilization gains the ability to manipulate the mechanisms of human cognition while still struggling to answer the most basic question of all: what is a human being?

What Actually Happened

In 2022, Australian biotech company Cortical Labs demonstrated that networks of living human and mouse neurons grown on a silicon chip could learn to play the video game Pong. Smithsonian Magazine reports that the neurons received electrical feedback from the game environment and adapted their responses over time to improve performance. Researchers described the system as displaying adaptive or sentient-like behavior in the limited sense that it responded to feedback, adjusted its actions, and improved performance over time. Not that consciousness had been demonstrated. That distinction matters. The experiment did not prove self-awareness, emotion, or subjective experience. But it demonstrated something remarkable: living neurons outside a human body were able to process information, adapt to stimuli, and improve their behavior in response to changing conditions.

In 2025, Cortical Labs introduced the CL1, which the company describes as the world’s first commercially available biological computer. Popular Science reports that the system maintains approximately 200,000 living human neurons inside a life-support chamber connected to a silicon microelectrode array. Developers can interact with the system remotely through a Python API. In early 2026, an independent developer created an interface that allowed the CL1 to interact with the video game DOOM. GameDaily reports that the experiment demonstrated biological learning systems interacting with a complex three-dimensional digital environment, with the neurons seeking enemies, shooting, exploring corridors, and adapting through failure and feedback. The developer who built the DOOM interface, Sean Cole, had no prior experience in biological computing and completed the project in under a week using Cortical Labs’ publicly available API. The line between biology and computing is no longer theoretical. It is becoming operational.

Why Scientists Are Genuinely Excited

It is important to understand why many researchers view this technology as promising rather than frightening. Biological computing represents a fundamentally different approach to information processing than traditional silicon-based systems. Human neurons are extraordinarily energy efficient. They learn from experience rather than requiring every action to be explicitly programmed. They adapt dynamically to changing environments.

Researchers believe systems like the CL1 may eventually help scientists model neurological diseases, study disorders such as Alzheimer’s and epilepsy, test medications more efficiently, and better understand how learning actually works inside the human brain. The potential medical applications are significant. This is not a technology being developed primarily for entertainment. It is being developed by scientists attempting to better understand one of the most complex structures in existence: the human brain. A serious Christian response should avoid caricaturing every scientific breakthrough as inherently evil. Much of modern medicine exists because researchers were willing to explore difficult questions about biology and disease. But acknowledging the legitimate goals of the science does not remove the deeper ethical and philosophical questions the technology creates.

Why So Many People Feel Uneasy

Even people fascinated by the science often feel an immediate sense of discomfort when they hear about human neurons being grown on chips and connected to software systems. That discomfort deserves thoughtful examination rather than dismissal.

Part of the unease comes from the question of consciousness. No one currently knows whether sufficiently advanced neural systems could ever possess any form of subjective experience. Most scientists would say there is no evidence that systems like CL1 are conscious. But the deeper issue is that neuroscience itself still does not fully understand what consciousness is or how it emerges. And that uncertainty matters ethically. If living neural systems become increasingly complex, society will eventually be forced to confront questions it is not prepared to answer.

The second source of unease is civilizational. Technology is advancing faster than the moral frameworks governing it. That pattern appears repeatedly throughout history. Human capability expands rapidly. Ethical reflection lags behind. The result is often a civilization that becomes technically powerful while remaining morally disoriented. One of the most revealing realities about the current moment is not merely that scientists can grow neurons on silicon chips. It is that society can do something this profound while still lacking consensus about what a human being fundamentally is. That is not merely a scientific problem. It is a philosophical and spiritual one.

What Scripture Says About Knowledge and Wisdom

It is important to state clearly what this article is not arguing. This is not the mark of the beast. It is not proof that scientists have created consciousness. And it is not evidence that technology itself is evil. The more measured and biblically responsible observation is this: Scripture described a generation marked by extraordinary increases in knowledge and capability, while simultaneously warning that human wisdom detached from God would become unstable and self-destructive.

“But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased.”

— Daniel 12:4 KJV

The increase of knowledge Daniel described is difficult to deny in an age where living neurons can be integrated with computational systems and accessed remotely through cloud infrastructure. But Scripture never presents knowledge alone as the solution to humanity’s problems. In fact, Scripture repeatedly warns that knowledge without wisdom can become dangerous.

“Professing themselves to be wise, they became fools.”

— Romans 1:22 KJV

Paul’s warning in Romans is not directed at ignorant people. It is directed at civilizations that become extraordinarily advanced while losing sight of the Creator who gave them their abilities in the first place. The issue is not intelligence. The issue is orientation. A civilization can become technologically brilliant while becoming spiritually confused. And much of the modern world increasingly reflects that contradiction: immense technical power alongside declining moral clarity, expanding capability alongside diminishing wisdom.

The Question of the Image of God

The deepest issue raised by technologies like biological computing is ultimately theological.

“So God created man in his own image, in the image of God created he him; male and female created he them.”

— Genesis 1:27 KJV

Human beings are not merely biological machinery from a biblical perspective. They are creatures made intentionally in the image of God, possessing dignity and value that transcend material function alone. That truth matters profoundly when discussing consciousness, cognition, and human identity. Science can analyze neural activity. It can study learning behavior. It can model biological systems. But science alone cannot answer why human life possesses intrinsic value, what consciousness ultimately is, or why human beings matter morally. Those are theological questions. And a civilization attempting to answer them without a theological framework risks becoming increasingly powerful while simultaneously losing its understanding of the sacredness of human life itself.

The Babel Pattern

Scripture contains another pattern that feels increasingly relevant in moments like this.

“And they said, Go to, let us build us a city and a tower, whose top may reach unto heaven; and let us make us a name.”

— Genesis 11:4 KJV

The problem at Babel was not architecture. It was humanity attempting transcendence without dependence on God. That pattern repeats throughout history: capability expands, humility diminishes, power increases, wisdom fails to keep pace. The modern technological age often reflects that same tension. The drive to merge biology and machine systems, to overcome human limitations, to redesign cognition itself, is not automatically immoral. But it does reveal a civilization increasingly confident in its ability to redefine boundaries that previous generations viewed with caution. And Scripture consistently warns that human beings function best not when they abandon dependence on God, but when knowledge operates under wisdom rather than above it.

“The fear of the Lord is the beginning of wisdom: and the knowledge of the holy is understanding.”

— Proverbs 9:10 KJV

Not the conclusion of wisdom. The beginning. A civilization that can grow neurons on chips still needs wisdom. And that wisdom does not emerge from the laboratory. It begins in reverence for the God who created the human mind in the first place.

What This Moment Calls Believers to Do

The proper Christian response to developments like biological computing is neither panic nor anti-scientific hostility. It is discernment. It is intellectual seriousness. It is ethical clarity. And it is humility. Christians do not need to fear scientific advancement. But neither should they surrender moral reflection to technological momentum alone. The existence of a capability does not automatically answer whether every possible application of that capability should be pursued.

“What is man, that thou art mindful of him? and the son of man, that thou visitest him? For thou hast made him a little lower than the angels, and hast crowned him with glory and honour.”

— Psalm 8:4-5 KJV

That question matters more now than ever. Because humanity has entered an age where it can increasingly manipulate the mechanisms of intelligence itself while still struggling to answer the simplest and oldest question in history: what does it actually mean to be human? The knowledge is increasing exactly as Scripture said it would. The deeper question is whether wisdom is increasing with it.

“Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.”

— Revelation 14:12 KJV
