A photograph of the switch room of an old telephone exchange, lit by fluorescent tubes. Two ranks of tall steel relay racks run away from the camera down a narrow aisle, their faces packed with thousands of small contacts and bundles of red, blue and white jumper wire; the far third of the hall is unlit and goes to black. In the left foreground two engineers in white shirtsleeves work at a rack, one of them lifting out a large coil of stripped coloured wire, with a wooden crate of more of it on the floor at their feet. A third man in a shirt and tie walks up the aisle toward the camera reading a clipboard. Standing alone on the right, between the racks and under a lit tube, is a man in a grey suit a half size too big, seen from behind and turned to look back over his shoulder up the hall toward the dark end: white greasepaint, rose-pink painted rings round his eyes, a pink nose, a lavender wig. A single brown paper bag hangs from one hand at his side. None of the three men has noticed him.

The other side of the machine

S&P 500 6,832.76 · −108.71 · −1.57%

For two years the artificial-intelligence build had been a reason to own almost anything. On 12 February the market spent a day considering the same build from the other end — as a thing that arrives at a business and removes the need for most of it — and it did not enjoy the exercise. The index made its high of 6,973.22 ten minutes after the open, gave up a hundred and eighteen points by twenty past eleven, spent five hours going nowhere in particular, and then broke in the last half hour to finish at 6,832.76, down 1.57 percent, with the low of the day printed inside the final ten minutes. Utilities rose. Packaged food rose. That is what this kind of fear looks like while it is still polite: not a run for the exit, but a quiet, orderly move into the two industries that no software has ever been able to explain away.

The day's protagonist

Cisco Systems CSCO

Move: −12.32% to 75.00 — the fear arrives with a number attached

Cisco makes the switches and routers that the data centres are built out of. If the artificial-intelligence build were an unambiguous good for the companies that supply it, Cisco is the last place you would expect the doubt to land. It guided the current quarter down anyway, and the stock opened at 79.61 — a gap of nearly six dollars below Wednesday's close, before a single share changed hands in the session — traded down to 74.085, and finished at exactly 75.00, off 12.32 percent, on twice its normal volume. It was the worst thing in the Dow and it dragged the average down 669 points. What made the day frightening was not the guidance, which was one company's quarter. It was that the guidance was the first hard number anybody could attach to a soft, widely held, entirely unquantified worry: that the build could be enormous and real and still not pay the people building it. Apple fell exactly five percent the same afternoon on no news at all. Money went into utilities, up 1.5 percent, and consumer staples, up 0.9 — the two sectors whose businesses are the hardest to describe as software problems.

The deeper account

The selling came in two pieces with a long flat stretch between them, which is a useful thing to look at. The first piece was the morning: from 6,973.22 at twenty to ten down to 6,854.94 by twenty past eleven, a hundred and eighteen points in under two hours, which is a market reacting. Then nothing — five hours in a forty-point band, up a little, down a little, the shape of a market that has priced the news and is waiting to see whether anyone disagrees. The second piece was the last thirty-five minutes, when it went out on its low. Afternoon lows are the tell. A market that gaps down and recovers has absorbed something; a market that spends the day steady and then breaks at the bell has decided something.

The thing it decided was not about Cisco. Cisco's quarter was the occasion. The subject was a proposition that had been floating around, unpriced, for most of a year: that the artificial-intelligence build might be simultaneously the largest capital programme in modern corporate history and a net destroyer of the earnings of most of the companies that are not building it. Every previous version of that worry had been abstract. This one came with a number and a share price, from a company that sells the shovels, which is why a single set of quarterly guidance took two percent out of the Nasdaq.

What the money did next is the part worth recording. It did not leave. It moved into utilities and consumer staples — power and groceries — which rose while everything else fell. That is not panic; panic sells everything and asks later. It is a specific, considered proposition about which businesses a model can be pointed at, and it is the same proposition, in a much politer form, that the market would spend the rest of February arguing with itself about. Then, on the last day of the month, the war started, and for the next five weeks nobody discussed artificial intelligence at all.

The cease-of-service sheet. Every bay tests serviceable and every bay is marked to strip, which is the entire argument of 12 February set down in two columns: the equipment works, and that turned out not to be the thing being priced.
