The cargo cultists of Melanesia built control towers out of bamboo. They had watched American air-traffic controllers sit in towers, wear headsets, wave signal paddles — and watched planes full of cargo land. So they reproduced the tower. Lashed bamboo into the shape of the thing, sat a man inside it, gave him wooden headphones, and had him perform the motions of control. The structure looked right. It controlled nothing. No plane was ever guided by a bamboo tower, because the tower was never what guided the planes.
We have built our own bamboo control towers, and we sit in them now, performing oversight of systems we do not actually control.
The shape of control without the substance
A real control tower works because it is wired into something — radar, radio, a flight system that responds. The bamboo tower copied everything visible about the real one and missed the only thing that mattered: the connection to the mechanism. From the outside, the two are indistinguishable. A man in a tower, headset on, waving paddles. The difference is entirely invisible, and entirely decisive.
This is the exact failure mode of governance theater around powerful systems. The dashboard that shows green. The “human in the loop” who approves at a rate that makes genuine review impossible. The alignment review that produces a document. The safety eval that everyone runs because everyone runs it. Each of these has the shape of control — the tower, the headset, the paddles — and the honest question about each is the bamboo question: is this wired into the mechanism, or is it lashed into the shape of being wired in?
Why we build them anyway
Nobody builds a bamboo tower cynically. The cultists weren’t faking; they were doing their sincere best to summon a result they wanted using the only model they had — copy the form, hope for the cargo. Our governance theater is built the same way: sincerely, by people who genuinely want the system to be safe and controlled, reproducing the visible forms of control because the actual mechanism of control over an opaque system is hard, sometimes not yet invented, and the forms are available right now.
The bamboo tower is what you build when you need control to exist and don’t yet have the real thing. It is a placeholder that feels like a solution. And the danger is precisely that it feels like one — the green dashboard discharges the anxiety that should have driven you to build real control. You sat in the tower, you waved the paddles, the ritual of oversight was performed, and so the question “are we actually controlling this?” feels answered when it has only been costumed.
The bamboo test
For any piece of oversight you rely on, ask the bamboo question plainly: if this control were purely cosmetic — if it were lashed bamboo wired to nothing — would I be able to tell from where I’m sitting? If the honest answer is no, you are in the tower. That doesn’t mean the control is fake. It means you don’t currently have the evidence to know it’s real, which, for a control you’re depending on, is the same risk wearing a calmer face.
The cultists waited in their towers for planes that no tower could summon. The towers weren’t a lie they told. They were a hope they built, in the shape of control, over a void where the mechanism should have been. The first step out is just to check whether your tower is wired to anything.
