10 Will AI take your job? Workforce and economics
About 60 minutes
TipIn short
- The idea. In 2016 the most confident forecast in medicine said radiology would disappear. It failed because it mistook a task for a job. Four questions (tasks, generalization, liability, demand) let you judge any forecast about your own specialty.
- What you do. Ask ChatGPT Edu to apply the four questions to your specialty and find studies of how its working day is spent, then check one in PubMed.
- What you keep. A three-line forecast for your specialty, with a number and its source, to reread at the end of residency.
- Short on time? Read “What actually happened” and “Why ‘he was just early’ is not enough”. Do Part A.
NoteWhat you’ll learn
By the end of this chapter you will be able to:
- Say what was predicted for radiology in 2016, what the original data (match tables and workforce studies) show happened through 2026, and why “he was just early” is not a good enough explanation.
- Ask four questions of the specialty you are entering. Does the job break into tasks? Does the tool work outside the hospital that built it? Who is liable? Does demand grow? Then use the same questions to check a chatbot’s forecast about that specialty.
- Use the story of computer-aided detection in mammography to explain why a tool being adopted and a tool improving outcomes are separate questions.
- Explain why a tool can cut work inside one hospital while raising cost across the whole system, and describe the “bot wars” pattern.
- Read the Bureau of Labor Statistics projections for three health-information jobs and explain why jobs that sit next to each other move in opposite directions.
- Name the task in your intended specialty that a machine could most plausibly take over, estimate what fraction of the job it is, and say what would change your estimate.
Course competencies: AIM-7 (workflow and systems), AIM-2 (critical appraisal), AIM-X (professional identity, the closing question).
What you need. Your university ChatGPT Edu or Copilot account and a browser. Nothing to install. Nothing in this chapter involves a patient. The time counts about 15 minutes of reading, a 2-minute clip, and about 35 minutes of doing; the longer video and Go deeper are optional.
10.1 The year everyone says radiology is over
It is September of your fourth year. You have your radiology letters, your program list, and a spreadsheet of interview dates. At a family dinner, an uncle who reads about technology asks why you would go into the one specialty the “godfather of AI” said should stop training people. He has the quote on his phone. In 2016 Geoffrey Hinton told a Toronto audience that people should stop training radiologists now. Within five years, he said, deep learning would obviously do the job better. Hinton would later share a Nobel Prize for the neural networks that make modern AI work.
Your uncle is not wrong that Hinton said it. He is not wrong that Hinton knows more about deep learning than anyone at the table. The question is what happened next. Does the way the prediction failed tell you anything about the job you are about to spend a decade training for? Not going into radiology? The same uncle has a version of the question for every specialty, and so does every chatbot. This chapter is about how to answer it with evidence.
10.2 Why this matters
You are choosing a specialty for the next thirty years, mostly on instinct and advice. Nobody can tell you how your specialty will look in 2056. But the most confident, most credentialed prediction that a medical job would disappear has now had its full time to come true. It failed in a specific way that you can learn from. A forecast that has failed is more useful than one that has not been tested yet. You can examine each assumption and see which ones were wrong.
There is a second reason, and your co-residents will not think of it. The people whose jobs are already changing are not physicians. Medical transcription is shrinking. Medical coding is growing. Both jobs are done close to where you will work. A resident who understands why is more useful to the team than one who is only relieved about their own position.
10.3 How it works
10.3.1 What actually happened
The prediction was five years. Ten years on, the National Resident Matching Program’s own tables show what happened in Figure 10.1. Diagnostic radiology offered more advanced (PGY-2) positions in 2026 than in any of the previous four years, and filled 98.4 percent of them. There were 1,741 applicants who ranked the specialty for 1,083 positions.1
The other workforce numbers agree. The Neiman Health Policy Institute counted 37,482 radiologists serving Medicare patients in 2023. It projected a workforce 25.7 percent larger by 2055 even if residency positions stop growing, and 40.3 percent larger if they keep growing (Christensen, Parikh, et al., 2025). Attrition, the rate at which working radiologists leave clinical practice, more than doubled between 2014 and 2022, from 1.1 to 2.5 percent a year. The authors treat that as one cause of a shortage, not a surplus (Christensen et al., 2026).
In May 2025 Hinton told the New York Times that he had spoken too broadly in 2016. He said he had meant image analysis rather than the whole job. He now expects most image interpretation to be done by “a combination of A.I. and a radiologist.”2 Here is the prediction as it was covered when it was new, and as it reads now.

Match Day 2026: Radiology programs offer more positions than ever, but applicant pool declines
March 2026
Read the third clipping twice. “More positions than ever” and “applicant pool declines” are in the same headline. The headline does not prove why the pool shrank. But if students are hearing the prediction and acting on it, even as the job market moves the other way, that is a harm the prediction did, and the people who believed it were the ones harmed.
10.3.2 Why “he was just early” is not enough
The easy explanation is that the prediction was only late. Hinton’s own 2025 correction is more interesting. He says he meant a task, image analysis, and said a job. That is not a timing error. The most useful explanation of the failure has four parts, each built into how medical work is organized. Each one is a question you can ask about any specialty. The worksheets later in the chapter call them the four factors.
1. Task decomposition: does the job break into tasks a machine can be tested on? A job can be automated only as far as it breaks into tasks a machine can be measured on. In 2012, one trained observer followed fourteen staff radiologists through their workdays at three hospitals, timing each activity. The radiologists spent 36.4 percent of their time interpreting images (Dhanoa et al., 2013). The rest went to protocolling requests (deciding how each scan should be done), supervising studies, procedures, talking with other physicians, and direct patient care (Figure 10.2). A tool that read every image perfectly would leave nearly two-thirds of the day untouched. It would not sign the report either.

"Image interpretation" : 36.4
"Clinical work other than reading images" : 43.8
"Other clinical" : 7.5
"Nonclinical" : 12.3
2. Generalization: does it work at a hospital that did not build it? A model that beats radiologists on a benchmark (a fixed test set) has beaten them on one dataset. Deep-learning models for pneumonia on chest x-rays were trained at one hospital system and tested at another. Performance dropped. The models could also tell which hospital an image came from with better than 99.9 percent accuracy. They had learned the scanner as much as the disease (Zech et al., 2018).
3. Liability: who signs, and who is blamed when it is wrong? Someone signs the read. Malpractice law judges the physician, not the model. The joint statement of the American, Canadian, European, Australasian, and North American radiology societies describes current tools as helping the radiologist’s interpretation, not replacing it. Tools that act on their own are treated as a separate question needing their own evidence (Brady et al., 2024). Where a device stops and who is liable when a tool is wrong belong to the ethics chapter. The point here is only that the rules are built to keep a human involved in every decision, and rules change more slowly than benchmarks.
4. Demand: if the task gets cheaper, is more of it ordered? Making a task cheaper does not obviously reduce the number of people doing it. This is the second of the course’s four recurring lessons, efficiency gains get eaten by volume; economists call it the Jevons paradox. In the nineteenth century, more efficient steam engines led to more coal being burned, not less, because cheaper power got used more. Imaging works the same way: cheaper scans get ordered more often. The Neiman Health Policy Institute projects 17% to 27% more imaging in 2055 than in 2023, driven mostly by population growth and ageing, if per-person use stays flat (Christensen, Drake, et al., 2025). Its companion paper projects the radiologist workforce growing 26% to 40% over the same years (Christensen, Parikh, et al., 2025). The workforce projection above assumes demand keeps growing at least as fast as supply. The same paradox appears again in the environmental-impact chapter, if you take it. Efficiency per unit and total use move in opposite directions more often than you would expect.

Most physician jobs do not break neatly into tasks. The specialties that look most automatable from outside are the ones whose pattern-recognition work is easiest to see, not the ones where it is the largest share of the work.
10.3.3 The precedent: mammography CAD
The closest earlier example went further than most students expect. Computer-aided detection (CAD) for screening mammography is software that marks suspicious spots on the image for the radiologist. The FDA approved it in 1998. Medicare began paying extra for it in 2002. By the late 2000s it was used on most screening mammograms in the United States, at a cost of over $400 million a year (Lehman et al., 2015). Measured by adoption, it was a success.
Then the outcome data arrived. Across 429,345 mammograms at 43 facilities, adding CAD lowered specificity (the share of healthy women correctly called normal) from 90.2 to 87.2 percent. It raised the biopsy rate by 19.7 percent. It did not significantly change the cancer detection rate (Fenton et al., 2007). A later analysis of 625,625 digital mammograms found no improvement on any measure with CAD. Among radiologists who read both with and without it, sensitivity (the share of cancers found) was lower with CAD (Lehman et al., 2015). From January 2018 Medicare stopped paying separately for CAD. The new mammography codes include CAD “when performed”, so the add-on disappeared into the base payment (CMS Transmittal 3844, 2017). A technology was adopted at scale, generated extra procedures for patients, and then disappeared once the payment stopped.
The finding to remember is smaller and worse. Readers were shown mammograms in which an unusually high share of the CAD marks were wrong. Their sensitivity fell compared with readers who had no computer output at all. It fell most on exactly the cancers the computer had missed (Alberdi et al., 2004). The name for this is automation bias: the habit of trusting a machine’s suggestion more than it deserves. It has been documented in aviation, in decision-support software, and in imaging (Goddard et al., 2011). CAD did not replace the radiologists. It made some of them worse. That is a different and more troubling failure than the one everyone was worried about. The same thing happens with the sepsis alert you will silence in your first month. A tool that is wrong in a systematic way makes the human worse rather than being corrected by them. The defence is the same in both places: find out how often the tool is wrong before you decide how much to trust it.
Adoption and outcomes are separate questions.
10.3.4 The economics the debate leaves out
Everything so far points toward optimism about physician jobs. This section complicates that, because “your job survives” and “the system gets better or cheaper” are different claims.
Within the organization. Ambient scribes are software that listens to a visit and drafts the note. At UCSF, a study followed 1,565 physicians and about 1.2 million outpatient visits. Physicians who adopted a scribe billed 1.81 more relative value units (RVUs, the units Medicare uses to price physician work) per week than those who did not. They saw 0.80 more patients per week, with no rise in claim denials (Holmgren et al., 2026). This is an association, not proof that the scribe caused the change; early adopters may differ from other physicians. More billing is what a hospital’s finance office hopes for, and it is not cost reduction. It fits the same recurring lesson: efficiency gains get eaten by volume.
Across the system. The Peterson Health Technology Institute takes no vendor money. In March 2025 it concluded that scribes probably reduce burnout but show little evidence of financial return. In April 2026 it concluded that administrative AI reduces work inside organizations while failing to lower system-wide costs, and possibly raising them.3 The pattern it names is “bot wars.” Providers use AI to submit more prior-authorization requests (the insurer’s approval needed before a treatment) and to code visits at higher levels. Payers use AI to process more denials and to “downcode” claims automatically, paying at a lower level than billed. The number of requests and denials rises, and no clinical question is settled any faster.
10.3.5 The most useful single fact: the BLS contradiction
The Bureau of Labor Statistics (BLS) is the United States government agency that publishes ten-year employment projections for every occupation, in its Occupational Outlook Handbook. Three of those occupations sit side by side in the medical records department (Figure 10.4).
| Occupation | 2025 jobs | Projected change, 2025–35 | BLS’s stated reason |
|---|---|---|---|
| Medical transcriptionists | 42,000 | −4% | Speech recognition and natural language processing let physicians document in real time |
| Medical records specialists | 200,700 | +8% | Aging population, chronic disease, more coding for reimbursement; AI coding tools “may affect” demand |
| Health information technologists and medical registrars | 42,000 | +16% | Growing volume of electronic health information needing analysis and registry maintenance |
What separates them is the same four questions, applied to non-physician work. Transcription is a single task a machine can be tested on. It works anywhere, because speech is speech. Nobody signs a transcript. And its demand is capped by the number of visits. Coding and health-information work fail the first test. The job is judgment about what a record means and what a payer will accept, and the bot wars above are increasing that work, not removing it. The people whose jobs change first are your colleagues, and the harm is not spread evenly. Transcription pays less than the two occupations that are growing, so the displaced workers are the ones with the least money in reserve. That is the course’s fourth recurring lesson, who benefits, who bears the risk, who decides, explained in the ethics chapter. The bias and equity chapter has a name for that, harms of allocation, and it applies to jobs as much as to diagnosis.
10.4 Watch or listen
First, the source (1 min 24 s). “Geoff Hinton: On Radiology,” Creative Destruction Lab, YouTube, uploaded 24 November 2016. https://www.youtube.com/watch?v=2HMPRXstSvQ. Watch it before reading anything about it. Notice how specific the claim is, how confident the tone is, and that the whole argument is about image analysis. He is describing a task and forecasting a job. That difference is what this chapter is about.
Then, if you have time, the other side (optional; the first 20 minutes). “AIMI Grand Rounds: Developing Clinically Useful AI for Radiology,” Curtis Langlotz, Stanford AIMI, YouTube, 30 January 2025, 59 min 37 s. https://www.youtube.com/watch?v=WS9p0wFw7uY. Langlotz is the radiologist who wrote, in 2019, that AI will not replace radiologists, but radiologists who use AI will replace those who do not (Langlotz, 2019). Listen for what he says makes a tool clinically useful, as opposed to merely accurate. Listen also for every place where the obstacle he describes is one of the four questions rather than model performance. Twenty minutes is enough for the exercise. The rest is worth hearing when you have time.
If you would rather read than watch, Deena Mousa’s essay, listed under Go deeper, covers the same material in about the same time.
10.5 Do
Made-up patients only. What counts as patient information.
10.5.1 Part A: ask the four questions with ChatGPT (15 minutes)
Step 1. Ask. Open ChatGPT Edu (Copilot also works) and paste this, with your intended specialty in place of <specialty> (or radiology if you are undecided):
I am a fourth-year medical student going into <specialty>. Use these
four questions to think about how AI may change the job by 2036:
1. Does the job break into tasks a machine can be tested on? Which ones?
2. Do tools for those tasks work at hospitals that did not build them?
3. Who signs the result, and who is liable when it is wrong?
4. If the task gets cheaper, will more of it be ordered?
Then search for two or three published studies of how <specialty>
physicians spend their working day (time-and-motion studies) or of the
<specialty> workforce. For each, give the authors, journal, year, a link,
and the number I should look for.Step 2. Record what it said. One line per question, and whether it gave you something you can check: a number, a study, a link.
Tool: ____________________ Specialty: ____________________
Question What it said (one line) Checkable?
Tasks ____________________________________ Y / N
Generalization ____________________________________ Y / N
Liability ____________________________________ Y / N
Demand ____________________________________ Y / NStep 3. Check one study. Ask, then check: most of a good answer is right, and your job is to find out which parts. Pick the study the answer leans on most. Open the link, or search its title in PubMed. Does the paper exist, and does its abstract contain the number the answer gave?
The study I checked: ________________________________ PMID: __________
It exists: Y / N It contains the number: Y / N
What I found: _________________________________________________________It may get this right. If so, you know because you found the number in the abstract yourself. If it got the study or the number wrong, tell it what you found and ask again. Either way, note which parts of the answer held up.
10.5.2 Part B: your own forecast (12 minutes)
Step 1. Find out how the time is actually spent. The 36 percent figure for radiology came from someone with a stopwatch. Most specialties have such a study. Use the one you checked in Part A if it held up. If not, search PubMed with:
"time and motion studies"[MeSH] AND <your specialty>adding physician or resident if the results are mostly about nurses. Read the abstracts of the two most recent studies that observed physicians rather than surveying them. Write down how the day divides. If your specialty has no such study, say so on the sheet. That absence is itself a finding about how well the job is understood. In that case, use your own sub-internship, labeled honestly as one observer’s estimate.
Step 2. Write three lines.
Specialty: ____________________
1. The most automatable TASK in this specialty (a task, not the job):
__________________________________________________________________
2. What fraction of the working day that task is, and where the number
comes from (study / my own estimate):
______ % source: ____________________________________________
3. The factor most likely to make my estimate wrong, and why:
[ ] task decomposition [ ] generalization [ ] liability [ ] demand
__________________________________________________________________Radiology’s 36 percent is the number to compare yours against. Most students overestimate the fraction for their own field when they first write it down. That is fine. The point of writing it down is to have a number you can check later.
Step 3. Argue against it. Reread your line 2 as the uncle at dinner. What would he say is missing? Then reread it as the radiology resident who wrote the first press clipping. Change the number if either of them convinced you, and say which.
10.5.3 Part C: check the numbers yourself (8 minutes)
The BLS projections change every two years. Read them from the source.
Step 1. Open the three BLS pages linked under Table 10.1 in your browser. For each, find the “Job Outlook” section and record:
Occupation Projected change Decade BLS's stated reason
Medical transcriptionists ______ % ____–____ ___________________
Medical records specialists ______ % ____–____ ___________________
Health information technologists ______ % ____–____ ___________________If your numbers differ from Table 10.1, BLS has revised the projections since this chapter was written. Note the new decade, and trust the page over the chapter.
Step 2. In two sentences, explain why the first occupation moves one way and the other two move the other way. Use at least two of the four questions by name. Then one more sentence: who bears the cost of the −4 percent, and what does that group look like compared with the +16 percent one?
10.6 Check
Score yourself against this before moving on. Objective numbers refer to the list at the top of the chapter.
| You have | Meets | Falls short |
|---|---|---|
| The prediction and its outcome (obj. 1) | You can state the 2016 claim, give two primary numbers from 2026 (positions, fill rate, or workforce projection), and say in one sentence why “early” is the wrong diagnosis | “He was wrong” with no number, or “he was just early” |
| The four questions for your specialty (obj. 2) | All four rows filled, and one study opened and checked against the number the answer gave | Rows filled without checking anything |
| Your three-line forecast (obj. 2, 6) | A task, not a job; a fraction with a named source or an honest “my estimate”; a factor with a reason | “Documentation, 50%, probably fine” |
| The CAD sentence (obj. 3) | “Adoption and outcomes are separate questions,” with the biopsy-rate finding attached | Only the slogan |
| The system-cost sentence (obj. 4) | You can explain in your own words why 1.81 more RVUs a week is not a cost reduction, and what “bot wars” means | “AI saves money” or “AI wastes money” without a mechanism |
| Three BLS rows (obj. 5) | Numbers and reasons read from the live pages, and a two-sentence explanation that names two factors | Numbers copied from this chapter |
10.7 What this changes for you
What does this change about how you’ll practice, and what would you have to see in the next five years to conclude you got this wrong?
Write both halves down. For the first, go back to the dinner table. Your uncle is still holding his phone. What do you say about the 2016 quote, using one number from this chapter and one of the four questions? If you are not going into radiology, answer for your own specialty, with your Part B line 2 as the number. For the second half, name the observation that would make you change your forecast: a match statistic, a workforce projection, a BLS revision, a change in who signs the report. A forecast that nothing could prove wrong is not a forecast.
Then keep the sheet from Part B. Reread it at the end of residency. Every student who does this exercise has just made a confident forecast about a medical specialty. So did a Nobel laureate, with better information than any of you, and he got the mechanism wrong. The point of writing it down is to be able to check.
Your forecast, and what would change it, can go into your week 4 piece, “what you will keep” (see the learning journal).
10.8 Go deeper
10.8.1 More numbers behind the story
Optional. These were in the main text and were moved here to keep it short.
Radiology pay. Doximity’s 2026 pay survey put average diagnostic radiology pay at $609,684 for 2025, up 6.6 percent in a year when physician pay overall rose about 2 percent (Doximity, 2026 Physician Compensation Report). The previous year’s report gave $571,749, up 7.5 percent. These are different survey years, not competing estimates, so quote one with its year.
The subspecialty exception. Count the radiologists who bill at least half their work for children. That pediatric radiology workforce shrank from 2,190 in 2016 to 2,032 in 2023, from 6.4 to 4.6 percent of all radiologists, while demand for imaging rose (Morales-Tisnés et al., 2025). That is not automation. It is the job market of one subspecialty moving on its own, apart from its parent specialty. A student choosing a fellowship is making a more specific decision than the overall numbers describe.
FDA devices. Radiology has most of the FDA-authorized AI devices. An analysis of the 903 AI-enabled devices the FDA had authorized by August 2024 found that 692 (76.6 percent) were radiology devices. It found a clinical performance study reported for about half of all 903 (Windecker et al., 2025). There are hundreds of cleared radiology tools, and so far no measured loss of radiologist jobs. The most widely read explanation of why is Deena Mousa’s essay “AI isn’t replacing radiologists” (Understanding AI, 1 October 2025). She also reports that 38 percent of models cleared in 2024 that disclosed their test sites used data from a single hospital. That figure is her reading of the same analysis; it is not in the paper’s main text VERIFY: not in the main text of pmid:40305017, checked 2026-09-08; the site counts would be in Supplement 1, which a person should open.
Scribes across five health systems. A study followed 8,581 clinicians at five academic health systems, 1,809 of whom adopted a scribe. Adoption was associated with modestly less time in the EHR and on documentation, and slightly more visits each week (Rotenstein et al., 2026). The Peterson Health Technology Institute’s April 2026 report also records a health system where Level 5 visit coding (the highest billing level for an office visit) rose 5 percent after scribes arrived, worth over $1,000 per provider per month. That is the UCSF finding seen from the payer’s side.
Percent of what? You will hear that “25 percent of health care spending is administrative.” That sentence blends three studies with three different denominators, that is, three different answers to “percent of what?” Shrank and colleagues estimated total waste at $760 to $935 billion, about 25 percent of spending. Administrative complexity is one of six categories of that waste (Shrank et al., 2019). Himmelstein and colleagues found administration to be 25.3 percent of hospital spending, the highest of eight countries (Himmelstein et al., 2014). Woolhandler and colleagues put administration at $294.3 billion in 1999, 31.0 percent of spending after exclusions, using the broadest definition in the literature (Woolhandler et al., 2003). Asking “percent of what?” will stay useful after all three figures are out of date. Test yourself: can you name the three denominators?

It also lists eight guiding principles (Badal et al., 2023). Two of them, “have high healthcare value” and “reduce overdiagnosis and overtreatment,” are the CAD story stated as rules. The deck is also in the ethics chapter; the principles are also in the appraisal chapter.
