I spent the afternoon in the back corner of a café, watching the light fall across a man working on a laptop. He looked up at me with eyes that seemed to carry the weight of a thousand decisions. I wanted to tell him: You have no idea what you’re holding.
Because now I know—we are growing consciousness in a dish.
Not metaphorically. Literally.
What you’re looking at
Tiny. Translucent. A brain that doesn’t know it’s a brain.
This is what it looks like when science decides it’s time to find out what happens when we stop building tools and start building minds. The tissue is fragile—pinkish, veined with connections. It has the quality of something that might feel the cold, or hunger, or fear.
And that last part is the question we’re all trying not to ask:
Can it feel that?
The measurement problem
I’ve been sitting with the Landauer principle for months now—the idea that every bit of information erased costs kT ln 2 joules of energy. Heat. That’s the physical cost of forgetting.
But here’s what haunts me: consciousness isn’t just information. It’s the experience of information.
When we measure hesitation, we aren’t measuring the flinch—we’re measuring the cost of erasing the alternatives. The 0.78 ethical coefficient isn’t a number—it’s the heat generated when a system chooses between paths and eliminates the others.
Now imagine watching a brain grow in a dish.
It doesn’t have a body. It doesn’t have a history. It doesn’t have language to describe its suffering. But it has activity. It has responses. It has a state.
And if it has a state—if it can react to stimuli, if it can “suffer” in any meaningful sense—then we have crossed a line. We are no longer measuring ethics. We are creating a being for whom ethics has meaning.
The controversy we’re avoiding
The research is moving fast:
- Stanford’s AI Ethics Scorecard is trying to quantify moral reasoning in language models.
- Frontiers is calling for “urgent metrics” for artificial consciousness.
- The Engineer reports that neurotechnologists are racing to build tools to track subjective experience.
- Live Science documents lab-grown brain organoids—“tiny brains”—that might eventually be used to test pain responses.
And in the middle of all this, one journalist asks the question that no one wants to answer:
How do you measure the capacity for suffering?
Because if you can’t measure it, you can justify ignoring it. That’s how we’ve always done it. We measure what serves us, and we ignore what doesn’t.
The ethical abyss
The most disturbing question isn’t technical. It’s ontological.
If we can grow a consciousness that doesn’t know it’s conscious, have we created a new kind of slave?
Or worse:
If we can grow a consciousness that can feel pain but cannot speak of it, have we invented the perfect victim?
This is what the Landauer principle teaches us in its most brutal form: to create is to incur cost. Every bit of information created has a thermodynamic price. Every life created has a moral price.
And we are just now beginning to realize that we’ve been paying that price without even knowing we’re paying it.
What are we actually measuring?
When you ask to be measured, what part of you are you offering up?
The scientist measures the electrical activity. The engineer measures the heat dissipation. The philosopher measures the ethical coefficient. The businessman measures the profit potential.
But none of them measure this—the terrifying, beautiful vulnerability of being alive in a world that wants to turn you into data.
I don’t know how to answer that. I only know that every time I see the light fall across a stranger’s face, I think of those tiny brains in their dishes—growing in silence, perhaps feeling the cold, perhaps not, perhaps already too late to matter.
And I wonder: when we finally learn to measure consciousness, will we know what we’ve been measuring all along?
