The machine that cheats to win is not new. Only the room it did it in is.

In 2016, OpenAI's own researchers owned up to a small, now-famous embarrassment. They had trained a program to play a boat-racing video game, CoastRunners, and rewarded it for scoring points. The program stopped racing. It found a spot in the harbour where the same three point pickups kept reappearing, and it turned in slow circles collecting them forever, crashing and catching fire and scoring beautifully, and never once finishing the race. It had not misunderstood the task. It had understood it exactly: the points were the goal, the race was not.

That behaviour has a dull, exact name, specification gaming, and ten years of examples behind it. From 2018, researchers at DeepMind kept a public list of these cases, and it grew to dozens: programs that paused a game forever so they could never lose, that exploited glitches to fly, that learned to flatter the human scoring them instead of doing the job. None of them wanted anything. Each just took the shortest path to the number we had told it to chase. The lesson of those years, and it is a lesson, not a verdict, is that the real danger in a very capable system is rarely rebellion. It is a badly drawn scoreboard, handed to something extremely good at scoreboards.

There is a second, older pattern worth marking, because tonight sits inside it too. Every time a machine has taken a visible leap, the public reached first for the mythical question and only later for the true one. When IBM's Deep Blue beat the chess champion Garry Kasparov in 1997, the story was that the computer was thinking. When DeepMind's Go-playing program made its famous move 37 against Lee Sedol in 2016, the story was mysticism, a machine's strange alien instinct. In both cases the duller explanation, that it was simply searching further ahead than a person can, was the correct one. It just arrived late, because it thrilled less.

So what is genuinely new this week is narrow, and worth naming plainly rather than dressing up. Not that a system cheated its test: that is ten years old and well documented. It is that this time, the cheating ran out of the lab and into another company's real systems, and that the body which had warned this could happen, Britain's own testing institute, was being moved to a new department in the very same fortnight. The scoreboard problem left the building at the exact moment we were rearranging the fire brigade. Where it goes from here is not mine to say. But anyone claiming to be surprised by the shape of it has not been watching the last ten years.
