The Human Brain Is Better Than Artificial Ones
A recent report on a tiny cubic millimeter of human brain tissue landed like a thunderbolt into conversations about AI. The study described the speck as containing “about 57,000 cells, about 230 millimeters of blood vessels, and about 150 million synapses, and comprises 1.4 petabytes.” Those numbers ought to stop us cold and force a humble pause.
The researchers’ finding that such a speck packs 1.4 petabytes of information demands context. “[A] typical DVD holds 4.7 GB of data. That means a single terabyte of storage could hold 217.8 DVD-quality movies, while a single petabyte of storage could hold 223,101 DVD-quality movies.” Put simply: the human brain’s storage and wiring are staggeringly dense.
Small Slice, Huge Wonder
Podcaster Aakash Gupta said the study “should mass-humble every AI lab on the planet.” He went on: “We’re building AI systems that loosely mimic neural networks, while still unable to fully read the wiring diagram of a single cubic millimeter of the thing we’re trying to imitate. … Every AI model on Earth fits in a fraction of that. The brain runs on 20 watts and fits in your skull. The data center required to merely describe one-millionth of it would span 140 acres.” Those sentences are not boasting about humanity; they are a corrective.
It is easy to be dazzled by silicon and scale, but such marvels are pale imitations of what God made. The brain’s efficiency, power consumption, and integrated complexity point beyond mere accident to clever design. To deny that design is to shrink human identity to a series of chemical and electrical events with no deeper meaning.
Materialism insists that love, loyalty, and moral commitment are evolutionary tricks or “selfish gene” programming. That reduction robs marriage, sacrifice, and parenthood of their sanctity and weight. Scripture calls the human person more than a bundle of instincts: we are made in the image of God, wired for relationship and moral truth.
Some scientists will argue that further study will close the explanatory gap and leave no room for Creator language. Yet the more we map and measure, the more evident the depth and intricacy become. Like unpeeling an onion of wonders, every layer of discovery reveals new puzzles that point beyond mere material process.
Consider the temptation to worship our own inventions. When we treat AI as the summit of human achievement, we mimic Eustace’s mistake in Voyage of the Dawn Treader: “Even in your world, my son, that is not what a star is, but only what it is made of.” Knowing how something is made does not answer why it exists or who ordained the order behind it.
Faith does not fear science; it reads science as testimony. The cosmos and the creature both bear the fingerprints of a Creator who delights in complexity and relational beings. A wise Christian celebrates technological progress while refusing to let it dethrone the God who made minds capable of wonder.
Practical implications matter. If we accept a purely reductionist anthropology, social institutions fray and moral responsibilities erode. Families, churches, and communities will be tempted to treat human beings like data points rather than image-bearers who deserve dignity and care.
So what do we do with discoveries that expose our smallness? We respond with gratitude, awe, and guarded humility. We keep building useful tools, but we do not confuse tools for the craftsman who made the hand that wields them.

Technology can amplify both good and harm, and Christians must steward innovation with eyes open. That stewardship includes protecting relationships, speaking for human dignity, and pointing again and again to the God who designed minds that can know, love, and worship.
The brain’s mysteries are an invitation, not an eviction. They call us to worship the Maker who placed such wonder inside each skull and to live as people who recognize that utility and meaning are related but not identical.
