Slowing artificial intelligence, meaning reducing how fast new AI systems are built and put to use, is the right decision. That is the argument. It begins by acknowledging that getting there is hard.
Reducing the speed of AI innovation will be hard both practically and politically. The argument treats those as real obstacles. It reaches the same conclusion anyway.
The headline makes the sharper point. "I told you so" has value only when something can still be done with being right. If the harm from unchecked AI development proves difficult to reverse, then waiting for that harm to become undeniable is itself the mistake. The time to act, the argument goes, is before the evidence becomes impossible to deny.
