"If we stop building superintelligence, someone else will."
It is the conversation-ender in a hundred rooms. It sounds like geography and game theory. Often it is neither. Often it is a way to keep building while calling the build inevitable.
Try the same shape with a technology we already handled. "If we stop making CFC fridges, someone else will just keep making fridges."
Yes. That is the point. They kept making fridges. They stopped using the chemical that was opening a hole in the sky.
Two different nouns
A refrigerator is a service: cold food, vaccines, less spoilage. Chlorofluorocarbons were one way to get that service, and a disastrous one for the ozone layer once the chemistry was clear. The Montreal Protocol did not outlaw cold. It scheduled the phaseout of the substances doing the damage, funded alternatives for poorer countries, and backed the deal with trade pressure. Industry had said the phaseout was impossible. The fridges stayed. The CFCs went.
Superintelligence rhetoric collapses two nouns into one. "AI" becomes a single blob that includes cancer models, route planners, and a hypothetical agent smarter than the human species. If you refuse the last item, the slogan says, you have refused the first ones too, and someone less scrupulous will ship all of it. That is the CFC trick in reverse: pretend the poison is identical to the product so that removing the poison sounds like a war on the product.
We did not save the ozone layer by promising to build the hole first. We kept the fridge and retired the chemical.
What "someone else will" is for
Grant the fear its strongest form. A rival lab, or a rival state, might try to train through any line you draw. That possibility is real enough to plan for. It is also the possibility arms control was invented to handle. The answer to "someone else might build a nuke" was not "then we must test infinitely." It was verification, chokepoints on fissile material, and consequences for breakout.
Compute is messier than uranium, and no one serious pretends otherwise. It is still physical, expensive at the frontier, and routed through a short list of chipmakers, fabs, and cloud regions. That is enough structure to build inspections on, which is why compute governance shows up in every serious treaty sketch. "Someone else will" skips that work and goes straight to permission.
Notice who benefits from the skip. If restraint is framed as unilateral surrender, then the only adult posture is full speed. Investors hear destiny. Safety staff hear that slowing down is naive. The slogan does not need to win a debate about mechanisms. It only needs to make the third option, shared restraint, feel childish.
The fridge was never the enemy
We want narrow AI that diagnoses, designs drugs, and finds faults in bridges. Say that plainly so the smear does not stick. The foundation's line is a refusal to build systems that exceed and replace human control while the control problem is unsolved.
That is closer to "use other refrigerants" than to "ban cold storage." The people who collapse the distinction are borrowing the popularity of useful AI as cover for a capability that does not stay a tool.
What the ozone fight actually teaches
Montreal worked because the science got loud, substitutes existed, and holdouts faced trade costs. Superintelligence is harder on substitutes for "strategic dominance," and easier in one respect the slogan ignores: no major power has a coherent interest in a system that does not stay under anyone's command. Shared vulnerability is the raw material of a deal. We expand that case on the China myth page and in the race myth essay. The short version is that rival fear can fund a treaty as easily as it funds a sprint, once the hollow finish is visible.
Ask which noun they mean. Useful AI is not on the chopping block. Uncontrollable superintelligence is. For the second noun, defection risk is a reason to build enforcement, not a reason to pre-defect. The fridges kept running. The sky healed because people could tell the difference.
Common questions.
Did banning CFCs stop refrigeration?
No. The Montreal Protocol phased out ozone-destroying chemicals while refrigeration, air conditioning, and aerosols continued with substitutes. The dangerous input was restricted. The useful service was not abolished. That distinction is the whole point of the analogy.
Isn't AI different because there is no substitute for strategic advantage?
There is no substitute for being the only actor with an uncontrollable superintelligence, and that is exactly why the prize is empty. Useful narrow AI has many paths. The strategic fantasy is that someone can own a system that does not stay owned. A race to that outcome is a race to a chemical everyone has a reason to retire, not a race to a better fridge.
What if a defector keeps building ASI anyway?
That is an enforcement problem, the same class of problem nuclear and chemical regimes were built to handle: verification, chokepoints, and consequences. It is not solved by joining the defector. The compute supply chain is concentrated enough to monitor. The obstacle is political will, not a law of nature that says restraint is impossible.
