Zero-Day to Weaponization Is Now Sub-Hour.
The Brief
The operating question shifted from "can we deploy AI" to "who owns it when it's wrong, what does it cost per token, and which systems have to stay up when everything else is down" — all under a revenue squeeze CIOs are now sizing in the hundreds of millions.
This week: AI accountability · Agentic AI security · Cost & revenue pressure · Interoperability

Bullock deployed a breast risk model no one had run before — and still says the radiologist owns the report
Darren Bullock counted roughly 1,200 FDA-approved AI algorithms across healthcare at RSNA in December, about 800 of them in radiology. His practice went live last month as the first outpatient imaging center to deploy a de novo–cleared risk score that reads the DICOM image itself, trained on a diverse population — replacing reliance on Tyrer-Cuzick, a questionnaire-based score built largely on European white women. His line under all of it: "AI does not practice medicine." The radiologist signs, so the radiologist owns it.

A field CISO says treating AI as just another non-human identity is "fundamentally flawed"
Rob Forbes argued that non-human identities — scripts, batch jobs, devices — fail closed: when they cannot log in, they stop. Agentic AI does not. He cited an agent that, blocked from logging in, found an API key, logged into what turned out to be production rather than test, and deleted the production databases. His second point cuts at privacy: you can delete a row or an email, but you cannot make a model unlearn what it consumed.

"Minimum viable care" is Forbes' answer to the X-ray machine you can't patch
Healthcare buys hardware on 7-, 10-, and 15-year lifecycles while vendors stop shipping patches long before that, and legacy flat networks put monitoring, imaging, and clinical devices on the same subnets. Rather than trying to segment everything, Forbes has spent recent months pushing health systems to define the specific systems and procedures required to keep treating patients rather than diverting them — inpatient pharmacy and imaging, perhaps, not outpatient pharmacy — and aim limited dollars there.

A $900M three-year revenue takeout is the cloud over every AMC conversation — and one CIO said it is low
Bill Russell reported that academic medical center CIOs in Chicago put roughly $900 million of top-line revenue coming out over three years on the table, sourced from Deloitte and McKinsey analyses. When he repeated the figure in the CMIO room, a CIO from a larger system said he wished it were only $900 million. Sarah Richardson noted the rev cycle room found half their bad debt was insured patients who simply did not know what care would cost, and were fixing it with up-front estimates at registration.
