Plutonic Rainbows

The headline figure has been reported as more than a thousand publicly accessible pools closed across the country since 2010, with around forty-two per cent of those losses falling after 2020 alone. The acceleration is the part of the statistic that tends to get skipped. A slow attrition would suggest a shift in habits. A cliff means something else was paying for these buildings, and that something stopped.

The pools in question were rarely ordinary. Britain accumulated an unusual stock of municipal swimming infrastructure over a century and a half, and the Edwardian and inter-war buildings were architecturally ambitious in a way no leisure-trust replacement ever attempts. Moseley Road Baths in Birmingham opened in 1907 and has kept its swimming function essentially continuously since, which is rare for the period. It still has its forty-six original slipper-bath cubicles, the oak ticket offices and attendants' kiosks, and what may be the last steam-heated drying racks left in a British pool. That is a description of a building that was designed to do work most people no longer remember asking of a pool.

Slipper baths held the line. Households without indoor plumbing rented a private bathtub at the baths by the half-hour, with the towel and soap included on the higher tariff. The municipal pool was therefore not a sports venue grafted onto a town. It was the hygiene infrastructure, the lido in summer, the gala hall on Saturdays, and the cheap warm room for women allowed in on segregated days. When that function went, the buildings stayed.

The closures concentrate where the buildings did most of that work. Swim England's analysis found a hundred and sixty-nine pools lost in the most deprived parts of the country against forty-nine in the richest, and seventy per cent of the worst-affected local authorities fell above the average for multiple deprivation. The losses are not distributed across the map. They are tracing the same outline that council tax bases trace, that bus deregulation traced, that the post-PFI maintenance backlog traces.

Fifteen hundred more pools are over forty years old now, according to the same data, and considered to be reaching the end of their useful life. That figure carries the next decade inside it. A boiler from 1978 cannot indefinitely be coaxed back into compliance with whatever the current edition of the water-treatment regulations says. Either the council finds the capital to replace the plant, or the pool closes on a Friday afternoon and never reopens.

What is left in the closed buildings is harder to describe than the arithmetic. Drained pools hold their acoustics for a surprisingly long time. The tile lines, the diving stages, the numbered changing cubicles all survive the absence of water without obviously deteriorating, and the chlorine smell lasts in the grouting after the ventilation has been turned off for years. The first time you walk into one of these spaces empty, the strangeness is not the silence. It is that nothing about the room admits that anything has changed.

The pool buildings were never really about sport in the way the arithmetic of pool-closure reporting now implies. They were about a particular version of public provision, indoor heat that did not depend on whether your boiler at home was working, water that the council was responsible for keeping clean. We are not really losing swimming, which can be done in a private gym or a glassy hotel basement for a fee. We are losing the proposition that a town owes its residents a warm room with a roof on it, paid for in advance out of the rates. The buildings survive longer than that proposition does, which is what makes walking past them in 2026 a particular kind of unsettling.

Christian Lacroix's first show under his own name opened the Paris fall-winter couture week on Sunday 26 July 1987. Fashion editors stood on chairs. They threw flowers at the runway. Some of them cried, openly, and the Guardian's reporter wrote it down without irony because that was what was actually happening in the room. Lacroix was thirty-six. He had signed in February with Bernard Arnault's Financière Agache for fifty million pounds, which made him the first new haute couture house in Paris since Courrèges in 1965.

The Patou years had given the press a shorthand for what to expect. He'd been the house designer at Patou without a contract since 1981, and the couture mob had already noticed the puffball, the bullfighter jackets, the dropped waists trimmed with Provençal embroidery, the late-eighteenth-century engravings cut down to a mini-skirt and re-coloured. Those Patou collections sold to a small list of private clients and to a slightly larger list of editors who couldn't quite work out where this register was supposed to sit. It wasn't revivalist exactly. It wasn't ironic. The historical references were treated as a working vocabulary rather than as costume.

What changed in July 1987 was the scale of the production. Arnault had given Lacroix an atelier at 73 Rue du Faubourg Saint-Honoré fitted out by Élisabeth Garouste and Mattia Bonetti, the neo-baroque furniture-makers, and the cocktail party the night before the show ran until four in the morning while the seamstresses were still working on the last looks behind a screen in the next room. The collection itself read like Lacroix had finally been allowed to publish everything Patou had made him cut. There were short broadtail cocktail suits with matching cocktail hats. Embroidered short jackets over moiré taffeta ball skirts the diameter of a small dining table. An above-the-knee silver fox coat with a shawl collar at the back that dipped almost to the hem. The puffball returned, larger and louder, in colours Patou would never have signed off.

The pouf became the easy press story because it was photographable and because it stood for the wider question the collection was raising. Late minimalism was already where the smart money said women's fashion was going. The Helmut Lang years were underway in Vienna; Donna Karan had spent two years stripping the American wardrobe back; Prada was a few seasons away from inventing ugly chic. Lacroix walked into that climate and presented an evening dress that required two assistants to manoeuvre through a doorway, and the audience treated it not as a provocation but as a deliverance. Some of that was Provence. He'd come from the south, his references were genuinely Boucher and Lautrec and the regional dress he'd absorbed as a child, and the clothes carried that conviction without apologising for being out of step.

The ending of the story is harder to enjoy. Black Monday hit nine days before his New York debut in October. The customers who had worn the big poufs and the big jewels at the July show, Lacroix said later, were in black-rimmed glasses and menswear by spring. The ready-to-wear that Arnault's contract had been built around never quite caught up to the couture. LVMH eventually sold the house to the Falic Group in 2005, the haute couture activity wound down later in the decade, and Lacroix today designs operas and ballets and the occasional hotel interior rather than dresses. The July 1987 show sits inside that arc like a held breath. For exactly one week the direction of Paris fashion looked like it might be about to reverse, and the editors who climbed on the chairs were not wrong about what they had just seen, only about how long it would last.

Open Apple Music's lossless support page and a stubborn little unit appears: 16-bit/44.1 kHz (CD Quality). I don't need a compact disc to hear music at that setting. The disc has become the explanation attached to the setting, an optical carrier that once needed shelf space now reduced to a label in a streaming menu.

The number did not arrive by accident. In a Philips-hosted history of the compact disc, Kees Immink describes the Philips-Sony meetings that fixed a sampling frequency of 44.1 kHz and 16-bit quantisation for the common CD standard in June 1980. The full specification lived in the Red Book and, as the article notes, in an International Electrotechnical Commission publication. A commercial object began with a negotiated row of technical decisions.

There is nothing dreamy about a figure like 44.1 kHz. That is why its afterlife interests me. We usually imagine obsolete media through their surfaces: jewel cases cracked at the hinge, the rainbow underside of a disc, the particular clatter of a portable player in a coat pocket. The sampling rate sits below all of that. It was invisible when the CD seemed modern, and it remains invisible now that the music arrives without a disc at all.

Apple's current explanation of lossless audio says that most of its Music catalogue is encoded with ALAC in resolutions ranging from 16-bit/44.1 kHz (CD Quality) up to 24-bit/192 kHz. Higher figures have become available, but the old figure still does useful work: it tells a listener what the basic lossless tier means. The stream borrows a vanished household object as its unit of reassurance.

I am more taken with this than with a retro skin drawn around a digital player. A skeuomorphic button can be redesigned next year. A standard is stickier, because manufacturers, catalogues, mastering work and listeners' expectations accumulate around it. Even a clean, modern download has to explain itself against a disc first sold when a home music library still meant furniture.

Compact discs were never as frictionless as their promise. My earlier post on pre-emphasis on early Japanese CDs stays with the physical object: a particular copy, a particular listening memory. The 44.1 kHz trace feels stranger because it escaped the object. It does not require owning an old copy of anything.

Somewhere in a settings panel, CD Quality now sits beside choices a compact disc could not contain. I can select it without hearing a tray close or watching a display count tracks. The format did not merely leave recordings behind; it left a number that the present still uses to say what ordinary fidelity should be.

The site had been down for a few hours today, as I had to deal with .webp to .avif conversions that did not go well. In addition, a github commit went south and deleted over a hundred posts. It took me some time to manually track down the generated html and then reconstruct the markdown files for rebuilds.

A toy world is a forgiving place to build an intelligent machine. Put a few blocks on a table, give the program a neat description of them, and search can look uncannily capable. Add the furniture, the door, a person walking through it, the million irrelevant details a real room contains, and the trick becomes a bill. The machine has far too many possible next moves to examine.

That objection sat at the centre of Sir James Lighthill's review of British artificial intelligence. Submitted to the Science Research Council in 1972 and published the following year as Artificial Intelligence: A General Survey, the report did not argue that computers could do nothing useful. It argued that ambitious work kept running into the same wall: as the world a program needed to represent grew, the possible searches through that world grew violently faster.

Lighthill called this combinatorial explosion. I prefer the plainer description: intelligence was expensive precisely where it appeared to be general. A system could solve a carefully bounded problem by carrying a great deal of human knowledge inside it. Let the boundaries loosen, and the method began spending its time discovering how much it did not know. That is less a philosophical defeat than an engineering one, but funding committees tend to recognise engineering defeats quickly.

There is an awkwardness here. John McCarthy, in his response to Lighthill, did not deny the explosion; he objected that AI researchers had known about it all along. He argued that heuristics existed to reduce just this kind of search. The dispute was not between a sober mathematician and fantasists who had never met complexity. It was about whether the field's workarounds amounted to progress, or merely made small demonstrations look more impressive than they were.

Britain's later account of this period is more careful than the neat myth. A parliamentary history of AI evidence records the report's connection with the British AI winter, while resisting the idea that one hostile document simply switched off a living field. The historian Jon Agar makes a similar correction in his reassessment of the report: Lighthill mattered, but his report also landed inside an argument about what publicly supported science was for.

This is why the story feels different from an ordinary wrong prediction. The earlier American decision to reduce machine-translation support, which I wrote about in Pierce's Verdict, had a similar trap built into it: evaluate a field by what its present methods can deliver, and you may be entirely fair while still starving whatever method comes next. Lighthill's case is harder, because the expensive search never went away. Bigger machines and learned representations did not abolish the problem. They changed which parts of it we could afford to tolerate.

I distrust histories in which the critic is made foolish by subsequent success. He had found a live wire. General systems still become costly when the world they must handle expands, even if their failure now shows up as a compute invoice or an answer produced without enough grip on the facts. The frustrating part is that a serious objection can be both true and mistimed.

The surviving document has the dry force of a public expenditure review: show me where this scales. It is not a glamorous demand. It is also the question that keeps returning whenever an impressive demonstration asks to be mistaken for a reliable world.

Dunmail Raise is not where I would choose to discover that a car had stopped cooperating. On the A591, the old AA telephone box appears in the records as a point of practical help: box number 487, placed on the Keswick-Grasmere road, ten miles south of Keswick, in the AA's historical list of roadside boxes. What survives now is less a telephone than a small black-and-yellow instruction in how fear once worked.

Before a mobile could turn a breakdown into an administrative nuisance, the road retained stretches where contact had a location. You had to reach the box. Weather, darkness, an injured passenger, a car that couldn't be left unattended: each fact counted while the telephone stood elsewhere, fixed and indifferent. I don't miss that vulnerability, but I do recognise the peculiar dignity of an emergency system that admitted distance rather than disguising it.

The AA's own timeline records the turning point with unusual neatness. In 1968 its wooden sentry boxes were phased out, apart from those protected by listing or retained in scenic places, as the network peaked at 787 boxes. In 2002 the telephones were decommissioned because mobile phones had made them redundant. Between those dates, the box moved from active equipment to something the landscape could keep after its reason for being had gone.

Number 487 had acquired another kind of protection before that final switch-off. Historic England lists the box as Grade II, first listed on 27 January 1987, its photograph still showing the black structure with AA yellow lettering and the number set out on the eaves. Listing is an odd form of aftercare. It can preserve the shelter, the paint scheme, perhaps the exact scale of a door, but it cannot preserve the moment when opening that door altered the odds of getting home.

I am tempted to call the box comforting, and that isn't quite honest. Its whole design assumes a failed journey. It belongs to the old grammar of the road: know the route, note the last petrol station, be aware that the next human voice may require a walk. The smartphone has improved most of this beyond argument. It has also thinned the visible evidence that we depend on systems at all. A call now seems to rise from the hand, not from a maintained network, charged battery, mast and contract.

There is a yellow severity to an AA box that the red public telephone kiosk doesn't have. A red box could be social, even faintly theatrical; the black and yellow box speaks only of trouble and the organisation summoned to deal with it. On an exposed road that narrow purpose must once have been a relief. Now it makes the surviving structure unusually stark: an emergency verb left behind after the sentence has changed.

Passing box 487 today would not make me want the old arrangement back. I would still check the charge on my phone and keep driving. Yet the little listed box marks something that constant connection has made difficult to feel clearly: help used to occupy a place in the landscape, and until you reached it the road was allowed to keep you waiting.

On Saturday, DeepSeek announced that the 75% discount on its flagship V4-Pro model is no longer a discount. It's the price. The promotion was due to expire on 31 May; instead the company locked the new rates in indefinitely. Output tokens now cost $0.87 per million. Cached input sits at $0.003625. The standard input rate is $0.435.

For context: GPT-5.5 charges $5 per million input and $30 per million output. Claude Opus 4.7 is $5 in, $25 out. Decoder ran the comparison and put V4-Pro at roughly 34 times cheaper than GPT-5.5 on output, and about 52 times cheaper once you cross GPT-5.5's long-context tier above 272K tokens. Those gaps aren't margin; they are a different business model wearing the same product shape.

The framing of "price war" has been used for every Chinese model release since the original V3 in late 2024, and it has become a tired phrase. What is actually new here is the supply story. V4-Pro is the first Chinese frontier model that runs natively on Huawei Ascend 950 silicon rather than Nvidia. DeepSeek told customers at launch a month ago that prices would ease once Ascend 950 supernodes started arriving in volume, and warned that until then the Pro tier could cost up to twelve times more than the lighter Flash model because of compute constraints. Saturday's lock-in is the company saying the supply problem is solved well enough to commit to the new floor.

That is the part worth paying attention to. The token price is a headline; the chip pivot is the structural fact. US export controls on the most advanced Nvidia parts pushed Chinese buyers toward Huawei. A second layer of restrictions on chipmaking equipment slowed Huawei's own ramp. Both pressures are still in place. What changed is that DeepSeek has decided the Ascend pipeline is reliable enough to price against, which is a different kind of bet than running benchmarks on borrowed hardware.

The interesting question is what this means for buyers who do not live inside Anthropic or OpenAI's stack. The flagship tax was already collapsing inside the Western labs; you could get 95% of the quality for a third of the cost by dropping from full GPT to a mini variant. DeepSeek's move is a more aggressive version of the same trick, only the discount goes to roughly two cents on the dollar and the savings are independent of which tier of Western model you benchmark against. For a CTO running document analysis or codebase review across a million tokens of context, the math is no longer close.

The complications are real. Training-data provenance for V4 is opaque, Anthropic has openly accused DeepSeek of distillation against earlier Claude generations, and routing enterprise traffic through a Chinese API still trips most large companies' procurement processes. Whether that gets resolved through audited deployments, private hosting, or just slow erosion of caution is the actual question. Reuters reported DeepSeek is chasing a $45 billion valuation off this strategy. The playbook is Amazon Retail circa 2002: give up margin, take the demand, build the moat. The new wrinkle is that the moat is silicon made in Shenzhen.

There's a smaller observation underneath all this, which is that the phrase "frontier model" is starting to do too much work. V4-Pro is not the most intelligent model in the world. It is the cheapest model that is intelligent enough for almost everything, and that has become a separate axis of competition entirely.

Vogue's note on Gianni Versace's Fall 1992 ready-to-wear collection carried a sentence that has stayed with me longer than any of the photographs from the show. "Getting strapped required eight hands." The clothes were beautiful in the usual Versace way, all glow and gold and a kind of Roman-emperor confidence, but the line betrayed how much engineering it took to land the silhouette. A woman couldn't walk into one of these looks alone. The dress had become a small infrastructure.

Versace called the show Miss S&M, in the sort of unembarrassed register he had been working in for years. The runway pulled in the supermodels of the moment, the same handful of women whose faces Lagerfeld was reading against Rose Macaulay on the Chanel runway earlier that year. What separates the two shows is that Lagerfeld's was a literary footnote in couture; Versace's was a hardware shop. PVC, oxblood leather, silk straps with steel buckles, and the safety pins that would soon define the house: not yet the giant chrome ones that held Liz Hurley together at the Four Weddings premiere two years later, but the smaller silver ones already migrating from punk shorthand to evening-dress structure.

The reception split along a fault line that fashion writing still finds awkward. Helmut Newton, whose own work had been engineering women into hardware for thirty years, told Vogue he loved it. Suzy Menkes, less so. "I don't want women to be sex objects or any of that," she said immediately after the show, then added, "But, after all, women have a right to choose." It is the kind of line a critic delivers when the work has refused to give her a clean exit. She had walked into the show with a position and walked out with half of it.

Versace himself gave the season its post-show punctuation. At an AIDS benefit in New York a few weeks later, the same looks turned up on the guest list, and he crowed to The New York Times, "Last night, there were two hundred socialites in bondage." The quote is archived in the trade press as a kind of victory lap, although what it actually marks is the moment a collection's vocabulary crossed from runway to red carpet without anyone losing their nerve. The clothes were never meant for a dungeon. They were meant for the front of a benefit photograph.

The other thing the show did, almost by accident, was institutionalise the Medusa head. Versace had been using the face on stationery and press packs, but Fall 1992 is the season the trade press dates as the emblem becoming the house's permanent logo, set into safety pins, clasps, buckles and buttons rather than printed on labels. By the following summer the Medusa was as inescapable as the safety pin itself, and the safety pin had stopped meaning punk and started meaning Versace.

What I keep coming back to is the eight hands. The whole moment sits inside that small piece of stagecraft. A collection presented as transgression that required, to actually wear, a quiet conspiracy of dressers backstage. The clothes look like rebellion, but they behaved like couture, and the gap between the two is where Versace made his case.

The Chambre Syndicale finally let him in. For the Fall-Winter 1992-93 season, Thierry Mugler was invited as a guest member of the haute couture calendar, and the decision was less generous than overdue. Couture in the early nineties had a problem. Buyers were ageing into the seats, press coverage was thinning, and the houses kept showing variations on the same drape. What the schedule needed was someone who treated tailoring as engineering and the runway as a venue for argument.

He answered by booking the swimming pool at the Ritz.

There is a Numéro retrospective of nine Mugler collections that walks through this debut with some precision. The pool gave the collection its name. Twenty seamstresses moved into the atelier and worked the season around the corset, which is the structural detail worth pausing on. Most couture houses at that point were assembling the silhouette from the shoulder down. Mugler started from the waist and built outward, the way a coachbuilder starts from the chassis. The 1989 bodywork-bustier that Naomi Campbell wore in the Buick collection had already proved the principle on ready-to-wear. The couture debut was the same logic stretched to the disciplines the Chambre Syndicale measures you against: hand-finishing, fitted-to-the-body precision, no shortcuts.

The Ritz pool is a strange room for clothes. The tiles bounce sound around the edges in a way no proper auditorium would tolerate, and the chlorinated humidity is hostile to silk. None of that mattered, because the room is also a stage set, art-deco depth and water-light and chrome handrails that pick up flashbulbs. The venue did half the work of arguing that couture could still surprise. The other half was the clothes, which the FIT Fashion History timeline catalogues alongside his ready-to-wear pieces from the same year, the bustier and corset traditions running in parallel between the two calendars.

What it bought him was a ten-year permanent membership in the couture calendar, which is the unglamorous answer to why this debut matters. Mugler now had a decade of January and July slots. He used it to do the Cirque d'Hiver anniversary show, the chrome gynoids and Cardi-B-shell-dress couture of Fall-Winter 1995-96, and Les Insectes in Spring 1997 with Galliano newly at Dior and McQueen at Givenchy in the next seats over. The Ritz pool is the show where that runway access was paid for, in 20 sets of hands working sleeves that took weeks instead of hours.

The footnote that always gets cut from the legend is that Mugler had been ready for this membership for a decade. The 1984 Zénith spectacle, the Too Funky bustier worn down a 1992 runway, the Atlantes mermaids and the Buick bodywork: the structural vocabulary was already complete. The Chambre Syndicale spent ten years deciding what a body could do, and then handed him the keys to a room he had already furnished.
