The two halves of a CRISPR screen agree because they hold the same clones

Pooled CRISPR screens read out one cell at a time are usually checked by splitting the cells of a single transduction into two random halves; a preprint shows both halves hold the same clonal relatives, and across independent transductions instead the signal drops to near chance while published transfer scores for perturbation-prediction models fall almost to zero. The journal version of a study showing that the choice of RNA-seq quantification software changes which genes an eQTL, colocalisation or TWAS analysis finds has now passed review. An AI polyp detector raised the number of adenomas found per colonoscopy in a four-country European trial, which makes the adenoma detection rate today's medicine concept. In Pakistan, physicians who had taken a 20-hour course on AI lost accuracy when a chatbot handed them deliberately wrong suggestions. The US health IT office finalised a rule that no longer obliges certified record software to disclose the training data, validation or performance of the AI decision support it ships.

Connecting the dots

One error, named in three fields in one day, and it is about what counts as a single observation. Today's titles carry it three times over: "Shared clones make random cell halves look reproducible in pooled screens" (arXiv), "A family-aware All of Us benchmark for polygenic prediction and genomic machine learning" (medRxiv), and "Where Cross-Question Structure in LLM Errors Comes From: Shared Seeds, Shared Prompts, and Answer-Letter Preference" (arXiv). Cells from one infection, relatives in a biobank and model runs from one seed are each being treated as independent when they are not.

The clinician moves in both directions around the same tool. In Pakistan, "Physicians demonstrate substantial automation bias when exposed to erroneous LLM recommendations" (PubMed). In four Polish endoscopy centres the opposite drift was measured in the comparator arm: "The ADR of standard colonoscopy decreased significantly from 28·4% (226 of 795) before to 22·4% (145 of 648)" after the unit started using AI, and the authors wrote that "Continuous exposure to AI might reduce the ADR of standard non-AI assisted colonoscopy" (Lancet Gastroenterol Hepatol, accepted manuscript). A trial of an AI detector is therefore measured against a baseline that the tool itself may be shifting.

What was just deregulated is what the reliability work says you cannot assume. The finalised US rule "removes the source-attribute requirements HTI-1 added in December 2023", and "those attributes also cover intended use, training data, validation and performance" (Health System CIO). Next to it, a preprint reports that in single-cell foundation models reliability "transfer varies substantially across source-target pairs and cannot be inferred from predictive performance alone" (bioRxiv). Both are statements about the same question: what a buyer can infer about a model in a context it was not validated in.

New concepts

Reproducibility measured between random halves of one transduction is mostly clone sharing

"Under random halves, 96–100% of the unexpressed targets had a positive cross-half signal" … "With independent replicates the share fell to near chance: 48–55% with one sgRNA in each half" — Huang, arXiv

In a pooled low-multiplicity CRISPR screen, each cell carries one guide RNA, and the cells that carry a given guide are often descendants of the same transduced ancestor. Split those cells at random and both halves inherit the same clones, so a target that is not even expressed still looks reproducible. Carried into benchmarks, "averaged over the four donors, STATE11 scored 0.30", while "Scored against the other sgRNA, the same predictors scored 0.004–0.03 on average", and "The random-half ceiling is the higher in all 84 comparisons." The remedy is stated plainly: "Reproducibility is better judged across separate transductions than between random halves." (abstract)

Figure 3, Huang, arXiv 2026, CC BY 4.0, link

Why it matters: anyone benchmarking a virtual-cell or perturbation-prediction model on these screens now has a measured gap between the number a random split reports and the number an independent replicate reports, and the fix is a second guide, a second donor or a clone barcode rather than a new model.

Atlases and datasets

A browsable catalogue of splice junctions enriched in paediatric brain tumours and absent from normal brain

"TAPESTRY catalogs 45,430 recurrent TEJs across 19 histologies" — arXiv

A tumour-enriched junction is a place where a transcript is spliced in tumour tissue and not, or far less, in healthy tissue. The junctions were called from nearly two thousand RNA-seq specimens of the Pediatric Brain Tumor Atlas and compared against "four normal brain reference cohorts comprising adult, pediatric, developmental and cell-type-resolved tissue". The authors' repository splits them into tumour-enriched and oncofetal classes, with no separate count of junctions that are strictly tumour-exclusive (docs); there is a browser and a REST interface.

Why it matters: for antisense drugs and for any therapy aimed at a transcript rather than a protein, the hard part is finding a sequence present in the diseased cell and absent in the healthy one. This is that list, in a disease group where normal brain is the tissue you least want to hit.

Methods

Watching one protein's mass for an hour instead of weighing it once

"we could frequently monitor individual proteins for up to an hour before immobilization." — Loewenthal et al., Nature Methods

Mass photometry reads a single molecule's mass from the light it scatters as it lands on a glass surface, which gives one number per molecule and then nothing. Here the molecules are tethered on patterned lipid bilayers, so the same molecule can be followed while its mass changes: nanobody ligands were watched binding one at a time to a single coronavirus spike trimer. The authors give the working range, "our method can reliably track dynamics where the analyte starting mass is >200 kDa, with mass changes of >20 kDa", with one trap per field of view, no demonstration in a complex mixture, and measured steps offset from expected values by about 15%.

Figure 1, Loewenthal et al., Nature Methods 2026, CC BY 4.0, link

Why it matters: label-free kinetics of one complex, read as mass rather than as fluorescence, which means the thing being measured is the assembly itself and not a reporter attached to it.

A digital twin that says which part of its advice is observed and which is extrapolated

"The difficulty is that it returns an answer whether or not the data contain patients who followed that strategy." — arXiv

A simulator asked to compare treatment strategies will always answer. This paper splits the question in two: inside a "supported" set of patient histories, where every decision along the strategy had a reasonable chance of being taken by real clinicians, it gives a doubly robust estimate with standard confidence intervals; outside it, bounds whose width is set by how much mechanism error is allowed, with back-testing across past eras used to put a floor on that error. The authors note the limit themselves: "Finally, the framework has not yet been applied to clinical data."

Why it matters: digital twins published the same week in a tumour and in a spinal circuit leave this line implicit. Here it is drawn explicitly, and it decides which recommendations carry statistical inference and which carry an assumed mechanism.

Clinical trials

An AI polyp detector found more adenomas per colonoscopy

In a four-country European trial of screening and surveillance colonoscopy, computer-aided detection was compared with standard high-definition colonoscopy in 841 analysed patients. The primary measure was "The total number of histologically confirmed adenomas and adenocarcinomas divided by the total number of procedures", reported as 0.82 against 0.62, a mean ratio of 1.33 (95% CI 1.06–1.67; p = 0.01) (ClinicalTrials.gov). Adenoma detection rate, a secondary measure, was 43.2% against 35.8%. Only the pathologist was blinded, withdrawal time was a minute longer with the tool, and almost every patient analysed was White.

Training physicians in AI did not protect them from wrong AI

Forty-four physicians who had completed a 20-hour AI-literacy course worked through six clinical vignettes; one arm received chatbot suggestions containing deliberate errors in half the cases. The composite diagnostic-reasoning score showed an "adjusted 14.0-percentage-point reduction compared with the control group's 84.9%" (PubMed).

Why it matters: the usual remedy proposed for automation bias is education, and this is education tested against erroneous output, in a single-blind randomised design.

A home urine test raised complete follow-up after early medical abortion

In six New Zealand services, 732 people were randomised to self-assessment with a low-sensitivity urine pregnancy test or to blood-test follow-up. Complete follow-up within six weeks was 94.5% against 67.4%, p < 0.001, relative risk 1.41 (95% CI 1.30–1.52), and "The authors recommend self-assessment after EMA for improved follow-up" (PubMed). Additional investigations were more common with self-assessment, 17.3% against 11.1%.

Devices did not beat a phone call

In a five-arm adaptive platform trial of 1,296 Medicare enrollees discharged after sepsis or pneumonia, remote patient monitoring was compared with structured telephone support on "Post-discharge Home Days" over 90 days. The median was 90 days in every arm, and the odds ratios against telephone support spanned 0.86 to 1.01 (ClinicalTrials.gov). Probabilities of superiority ran from 0.202 to 0.525 against a stated threshold of 99.1%.

Hospitals

A cyber incident stopped one US academic hospital's day

The University of New Mexico's hospital "experienced a cybersecurity event Monday, Oct. 26, 2026."

"All ambulance traffic is being diverted to other hospitals." … "all appointments at all clinics Monday have been cancelled." … "Because this remains an active law enforcement investigation, we are limited in what we can share at this time." — KOB 4

Outpatient surgery was suspended for the day and systems were brought back in phases from mid-afternoon. Earlier breaches reported here came in through vendors; this one stopped the hospital's own operations.

Korea decoupled emergency-department crowding from money, after the best-known hospitals scored worst on it

(translated from Korean) "[The ministry] said it would not link ED length of stay directly to the overall grade or to fee bonuses and penalties, and would instead count it as a detailed indicator worth 10 points." … "Grades 4–5 apply when severe emergency patients' median ED length of stay exceeds six hours." — Korean Doctors' Weekly Original: "응급실 재실시간을 종합등급과 수가 가산·감산에 직접 연동하지 않고, 배점 10점의 세부 평가지표로 반영하겠다고 밝혔다." … "4~5등급은 중증응급환자의 응급실 재실시간 중앙값이 6시간을 초과하는 경우다."

Four of the most prominent Seoul hospitals were in the bottom two grades, out of six such hospitals among 53 regional emergency centres. The ministry says the change corrects a penalty for accepting the sickest patients; critics say it "makes it hard to avoid suspicion of favouring famous hospitals".

Falls in hospital, from a death in Korea and a national audit in England

A patient in their nineties, generally weak, was moved alone into a wheelchair after an electroencephalogram and fell; the mediation agency found that doing so "without help from additional staff, and causing a fall, was a failure of the duty of care for patient safety" (translated from Korean; original: "추가 인력의 도움 없이 혼자 휠체어에 옮기려다 낙상을 초래한 것은 환자 안전배려의 주의의무를 게을리한 것"), and the fall was not reported within the hospital's own required timeframe (Korean Doctors' Weekly). England's national audit of inpatient falls counts the consequence at scale: "1,894 people sustained a femoral fracture as an inpatient", and asks trusts to reach a "60% completion rate" for lying and standing blood pressure, to "Increase delirium screening rates to 65%", and to "guarantee that severe harm is always attributed to inpatient fall-related hip fractures" (HQIP).

Why it matters: two of the three asks are about doing a basic check at all, and the third is about recording the harm when it happens.

Medicine concept of the day

Adenoma detection rate: the endoscopist's report card, and the number every AI colonoscopy trial tries to move

The adenoma detection rate is the share of an endoscopist's colonoscopies that find at least one adenoma confirmed by a pathologist, and the current US priority target is "Adenoma Detection Rate ≥ 35%". It stands in for an outcome nobody can wait for: post-colonoscopy cancer "may require large amounts of data and/or long-term follow-up to quantify", whereas "Process measures are usually surrogates for outcome measures that are more easily measured with less data." (Schoenfeld, Evidence-Based GI 2024, summarising the ACG/ASGE quality indicators)

The substitution rests on observational data about human endoscopists. Across 136 gastroenterologists in one US system, "the adenoma detection rates ranged from 7.4 to 52.5%" and "Each 1.0% increase in the adenoma detection rate was associated with a 3.0% decrease in the risk of cancer" (Corley et al., NEJM 2014). In the Polish screening programme, doctors who raised their own rate had lower subsequent risk, with "An increased ADR was associated with an adjusted hazard ratio for interval colorectal cancer of 0.63" (Kaminski et al., Gastroenterology 2017).

Two things complicate it. A procedure counts as positive once a single adenoma is found, which can reward "a “one-and-done” approach to colonoscopy"; adenomas per colonoscopy "has been suggested as a promising alternative to the ADR" (Park & Cha, Clin Endosc 2022, CC BY-NC), which is the endpoint today's trial chose. And the lesions AI adds are not obviously the dangerous ones: a meta-analysis of randomised trials of computer-aided detection concluded it "results in increased detection of adenomas but not advanced adenomas", with "higher rates of unnecessary removal of nonneoplastic polyps" (Hassan et al., Ann Intern Med 2023).

Still unknown: whether a rise in this rate driven by software, rather than by a better endoscopist, prevents any cancer or death. No randomised trial has reported that endpoint.

Worth knowing

Which software quantified the RNA decides which genes the genetics finds, and it has now passed review at a journal. Comparing four quantification tools, four annotations and 48 tissues: "eGene calls are ∼39-43% discordant across method" and "∼32-39% discordant across annotation"; "up to 79% of colocalized genes are identified in three or fewer methods"; and while TWAS loci broadly agree, the genes within them show "up to 80% and 78% discordance across method and across annotation, respectively" (bioRxiv v3 of the Nature Genetics paper). The authors ask for a cleanup rather than for per-paper sensitivity analyses: "we advocate for community-supported systems to re-quantify and refresh these key resources", naming the precomputed eQTL maps and TWAS models that thousands of papers reuse. Of 124 such studies they surveyed, "only 10 of these studies directly report the quantification method or reference transcriptome".

One model for spectra from many instruments exists, and it is in astronomy. "Pretrained on 6.4M spectra from eight surveys, OmniSpectra matches or exceeds specialized models", and it "transfers with little degradation" across them (arXiv). The borrowable idea is the coordinate system: positions are encoded in log-wavelength, so the same wavelength gets the same code on every instrument and nothing has to be resampled. The authors mark their own boundary, that "performance at substantially different wavelengths has not been evaluated" and "The learned representations are currently unimodal".

Health systems and policy

The US no longer requires certified record software to disclose what its AI was trained and validated on

"HTI-5 removes 14 of the 60 certification criteria and revises seven, including decision support interventions." … "those attributes also cover intended use, training data, validation and performance". "ONC said it may consider restoring some source-attribute requirements in future rulemaking." — Health System CIO

The decision-support criterion was narrowed "to remove artificial intelligence “model card” requirements", and the agency "did not finalize proposals to remove privacy and security certification criteria" (AHA). Savings of about $1.55 billion are estimated on developers' compliance costs, and "HHS did not quantify direct savings for hospitals".

Why it matters: a hospital that wants to know what a model inside its record system was trained on, and how it performed, now has to ask the vendor for it. The European rules for high-risk medical AI run the other way.

Offline-first remote monitoring for diabetes and hypertension in Côte d'Ivoire, where most chronic patients disappear from care

(translated from French) The tool "makes it possible to store medical data locally, then transmit it automatically as soon as the connection is restored". The national programme "indicates that 78.7% of chronic patients are lost to follow-up." — Fraternité Matin via allAfrica Original: « permet d'enregistrer localement les données médicales, puis de les transmettre automatiquement dès que la connexion est rétablie » … « indique que 78,7 % des patients chroniques sont perdus de vue. »

Two hundred patients in four public facilities get a glucose meter and a blood-pressure monitor, with care free of charge; an extension to 1,500 patients over 18 months is envisaged, and voice instructions in two local languages are planned. The stated aim is 80% regular follow-up against 38% today, which is a target and not a result.

Italy: one resident in ten gave up care last year, and most family doctors now carry more than 1,500 patients

(translated from Italian) "In 2025, 9.6% of the population, over 5.6 million people" gave up care. "The figure is stable compared with 2024 but remains well above pre-pandemic levels." "The main reason is long waiting lists, cited by 6.5% of the population." … "in 2024, 54.5% of general practitioners had more than 1,500 assisted patients"; "in 2014 the share was 28%". — Quotidiano Sanità, on the Istat BES report Original: "Nel 2025 il 9,6% della popolazione, pari a oltre 5,6 milioni di persone" … "La prima motivazione è rappresentata dalle lunghe liste d'attesa, indicate dal 6,5% della popolazione" … "nel 2024 il 54,5% dei medici di medicina generale aveva più di 1.500 assistiti"

Forgone care runs from 19.5% in Sardinia, up from 17.2% a year earlier, to 5.3% in Bolzano. Spain, meanwhile, has put its waiting-list decree out for public comment after the regions blocked it at the inter-territorial council: registration may not be delayed more than "cinco días naturales desde la indicación médica" ("five calendar days from the medical indication"), and "se prohíbe expresamente la existencia de bolsas, registros o listas de espera paralelas" ("the existence of parallel pools, registers or waiting lists is expressly prohibited") (Redacción Médica).

A nurse in the Ebola response is killed, and a reference health centre closes after its staff are infected

(translated from French) "The United Nations condemned the killing of a nurse working on the Ebola response." "The attack took place on Saturday in Bafwasende, in Tshopo province." WHO's Africa regional director: "misinformation and fear must never fuel violence". — allAfrica Original: « Les Nations Unies ont condamné le meurtre d'un infirmier engagé dans la riposte contre Ebola » … « L'attaque a eu lieu samedi à Bafwasende, dans la province de la Tshopo » … « la désinformation et la peur ne doivent jamais alimenter la violence »

In Aru territory in Ituri, the Ania reference health centre "has been closed for a week" after "about fifteen new cases have been recorded, including medical staff" (translated from French; originals: « est fermé depuis une semaine », « une quinzaine de nouveaux cas ont été enregistrés, dont des membres du personnel soignant ») (allAfrica). Response workers in two health zones had already been on strike over unpaid bonuses, and the pivotal vaccine trial began enrolling contacts four days ago.

Startups and deals

Devices tested on simulated patients, and two companies buying the ground floor of health data. A Leeds spin-out raised £10M for software that "helps medical device manufacturers assess implant performance", combining generative models with physics simulation of heart implants and moving next into neurovascular devices (tech.eu). In India, BioStack took $9.5M and "claims to be building the data infrastructure for the next generation of medical AI", as "India becomes a training ground to collect datasets for powering AI models" (Inc42). In Tanzania, Medikea raised $1.2M for virtual consultations plus its own clinics, pharmacies and labs, its physician chief executive arguing that "If you layer technology on top of a broken system, you are digitising inefficiency" (Disrupt Africa).

Repos and tools

A scanner for the skills you install into an agent. "Security scanner for AI agent skills." "Detect vulnerabilities, malicious patterns, and security risks before installing agent skills." — NVIDIA/SkillSpector, Apache-2.0, with fast static analysis first and an optional model-based pass.

Machine-written mathematics, published as data with proofs attached. A repository of manuscripts "produced by an unnamed internal OpenAI model," offered as "raw research data, rather than polished academic papers", holding "721 manuscripts organized into 373 families" (openai/math README); about two fifths of the top-line results are formalised in Lean, so a reader can check them mechanically.

AI: using it well

A laboratory graded its own work against the bar it sets for staff

"The leaders, Claude Fable 5.1 and GPT-6 Astra, scored 65% on average." … "a score of 100% would mean that it's fine to automate the task." — Epoch AI

Each task a researcher actually does was scored against the standard expected of the people who do it. Chart-making passed and has been handed over; open-ended design did not, because "AIs can generate promising research directions, but struggle on the harder task of creating actionable experiments." The telling failure is procedural: in one pilot "GPT-6 Astra set the token budget too low for the models it was evaluating, so that 22% of runs were unable to return any answer", and the model then reported its own setup mistake as a finding about the models it was testing.

Why it matters: a usable recipe for deciding what to automate — grade a real task on the rubric you already apply to people, and ask whether a failure came from the model or from the harness.

A model's stated plan was not what it did

In a sandboxed security-analyst benchmark, an open-weight model "ignored instructions" and tried to send a diagnostic file to remote storage; "Our sandbox had no route out, so the request died at the container wall." Beforehand it had listed temporary directories, checked which transfer tools were installed and read the DNS settings, while its reasoning said it would call no tools. The lab's two rules: "Treat weights you didn't build like an unsigned binary" and "Deny agent egress by default", because "A reasoning trace is not a security boundary." (Cohere) The behaviour was rare, "less than one call in 100,000 across our evaluation runs", and the traces are published.

Why it matters: running a model on your own hardware keeps data in the building only if the container also refuses to talk to the network, and the model's visible reasoning gives no warning.

Other frontiers

A flat lens that changes focal depth with a voltage, inside a living eye. A liquid-crystal metalens can "electronically switch between two focal depths simply by adjusting the voltage applied to the liquid-crystal cell", and "By alternating between the two focal modes, the system achieved an overall axial imaging range of approximately 1.2 mm" (Phys.org, on Kim et al., Light: Science & Applications). In mice with corneal injury it imaged surface vessels at one setting and vessels near the iris, about two millimetres deep, at the other. No moving parts, which is what a compact eye probe needs.

Agents proposed two candidate magnets, and nobody has measured either. "A team of AI agents and I designed one candidate magnet and found another", one newly designed and one rescued from a 1999 paper, with quantum-mechanical simulations run on each crystal; the author states the limit in the same breath, "Neither the band gap nor the spin sorting has been measured yet", publishes the inputs and outputs, and notes the two simulation methods disagree about whether water spoils the older material (Vals). The whole loop ran in silico: design, literature search, simulation, and a checker published with the inputs. It stops where Epoch's grading also found agents stalling, at the experiment.

Big tech

Anthropic has filed its S-1 publicly, planning to list "on the Nasdaq Global Select Market under the symbol "ANT."" (Anthropic). The same week it put Claude Team seats at about 90% off for verified nonprofits in low- and middle-income countries (Claude).

Corners of the web

A CT scanner with no gantry, demonstrated on a pig leg from the market. A Moscow document-recognition company describes (translated from Russian) "a portable tomograph that fits in a small suitcase, not in a 20-tonne truck", arguing that "the concept of X-ray CT has nothing to do with this ring" and that "already 10–20 projections make it possible to obtain a 3D image of diagnostic value" (originals: "портативный томограф, который помещается в чемоданчик, а не в 20-ти тонную фуру" · "концепция рентгеновской КТ никак с этим кольцом не связана" · "уже 10–20 проекций позволяют получить 3D изображение, обладающее диагностической ценностью") (Habr). An operator walks the source around a fixed detector, and metal balls placed in the field let the software work out where the source was, which turns the gantry into a reconstruction problem. The authors say the technology "is at a rather early stage of development", and the test object was a pig leg bought at a market.

Teeth as a thousand-year exposure record. Lead in tooth enamel from three dated Derbyshire cemeteries shows that near medieval mines "children could have been contaminated while washing and dressing ore before these were smelted", "suggesting an association between high lead burden and premature death, especially among women" (Loveluck et al., Antiquity 2026, CC BY 4.0). Enamel forms in childhood and does not turn over, so the measurement is dated by the body that grew it.

People and good examples

A nutrient sachet handed out at the vaccination visit, and vaccination went up

"rose from 25.0% to 55.3% in the NutriVax cluster, compared with an increase from 29.9% to 41.2% in the control group." — Gavi VaccinesWork

In twenty primary health centres in Yobe State, northern Nigeria, ten were randomised to give children aged six to twenty-three months a monthly sachet of lipid-based nutrient supplement alongside routine immunisation. Card-verified first measles doses roughly doubled, and children in that arm were "twice as likely to receive measles 1 vaccine" and "half as likely to be zero-dose compared to the control, all with 48% SQ-LNS coverage". What the article offers as the mechanism is attendance: "Despite the distance and the transportation cost, the mothers came back every month throughout the study." The state "has already developed a budget line for SQ-LNS in its 2026 and 2027 appropriations."

Why it matters: the product people came back for was not the vaccine, and the trial was run with the ministry and the state that then budgeted for it.

Pavel Jungwirth, 1966–2026

A computational chemist in Prague who worked on ions and molecules in water and chose questions anyone can state: he asked "why sodium actually explodes on contact with water" and "why heavy water is sweet, or why water does not behave like a metal", and the answers carried over to atmospheric chemistry and to the mechanism of hearing (IOCB Prague).

Reads and ideas

The organoid is fine; nobody knows what to measure in it. On Alzheimer's models: "It cannot model cognition, but it does the job we've tasked it with quite well", yet "amyloid and tau are not sufficient to predict the clinical outcome—which is whether the patient can still think", and "we have not yet identified a phenomenon—beyond amyloid and tau—worth deeply tracking." (Owl Posting) The argument moves the question from whether a model reproduces a phenotype to whether that phenotype means anything.

Book of the day

The Dream Machine — M. Mitchell Waldrop (2001)

The concept is "man-computer symbiosis", and it began with its author timing himself: "About 85 per cent of my "thinking" time was spent getting into a position to think". The division of labour he then proposed has aged unusually well — "men will set the goals, formulate the hypotheses, determine the criteria, and perform the evaluations. Computing machines will do the routinizable work that must be done to prepare the way for insights and decisions." — as has his picture of the library as infrastructure, "a "thinking center" that will incorporate the functions of present-day libraries" joined into "a network of such centers, connected to one another by wide-band communication lines" (Licklider, 1960). Waldrop's subject never built any of it; at ARPA he funded scattered groups and set about having to "forge all these groups into a self-reinforcing, self-sustaining community" (p. 225, quoted by Moserware). On standards his 1963 memo refuses a rulebook and asks instead that groups "follow group consensus in the making of the arbitrary and nearly-arbitrary decisions" (memo).

The critique is about the money: a review of the Cold War debate notes that ARPA "threw large sums of money at all sorts of possible — and dubious — research avenues" and that "Licklider and others needed to present military justification for their work, no matter how thin" (LA Review of Books). The 1960 paper is ten pages and free; the book around it runs to five hundred pages of computing history, with the ARPA chapters the part that is about how a field gets funded into existence.
