Because of AI: a registry of measured AI benefits to people

1. Because of AI, the Hurricane Center called a Category 5 landfall in Jamaica about three days out, while Melissa was still a Category 1.

   Evidence BobservationalEvidence B: Large observational or population-level data with a credible benchmark.Attribution isolatedAttribution, isolated: The comparison isolates the AI's contribution: the arms differ only by the AI.Window in windowWindow, in window: The benefit occurred inside the last twelve months.

   Caveat: There is no lives-saved number and cannot be; the measured outcome is forecast skill, and the final call was made by human forecasters using the model.

   ~3days' warning on a Cat 5

2. Because of AI, there were an estimated 841 fewer injury-causing crashes across 270 million driverless miles.

   Evidence Coperational reportEvidence C: A company or government operational report with no independent comparison.Attribution isolatedAttribution, isolated: The comparison isolates the AI's contribution: the arms differ only by the AI.Window ongoingWindow, ongoing: It began earlier, is still delivering, and has new in-window data.

   Caveat: Company-produced, modeled comparison against an estimated human benchmark with an adjustment for roughly 32% underreporting of human injury crashes; not a randomized comparison of identical trips.

   82%fewer injury crashes

3. Because of AI, a baby girl was born to a couple who had been told there was no sperm to work with.

   Evidence Dsingle caseEvidence D: A single case or anecdote.Attribution only pathAttribution, only path: No human or conventional alternative existed in practice.Window in windowWindow, in window: The benefit occurred inside the last twelve months.

   Caveat: One case; STAR finds sperm in just under 30% of men diagnosed with azoospermia, and larger trials are still underway.

   2sperm found in 2.5M images

4. Because of AI, 1,660 TB cases were found in Ethiopia between January 2025 and March 2026 in screening programs that had no radiologist to read the X-rays.

   Evidence Coperational reportEvidence C: A company or government operational report with no independent comparison.Attribution only pathAttribution, only path: No human or conventional alternative existed in practice.Window ongoingWindow, ongoing: It began earlier, is still delivering, and has new in-window data.

   20192020202120222023202420252026

   pub

   Caveat: Program report, not a controlled comparison; "contributed to" means the AI flagged people for confirmatory testing, so the counterfactual is how many would have been found by symptom screening alone.

   1,660TB cases found

5. Because of AI, TB case notifications rose 80% in a tribal district of Chhattisgarh, India, including 20 confirmed cases in people with no symptoms.

   Evidence BobservationalEvidence B: Large observational or population-level data with a credible benchmark.Attribution only pathAttribution, only path: No human or conventional alternative existed in practice.Window pre-windowWindow, pre-window: The benefit predates the window.

   Caveat: Before-and-after design in a high-burden setting; national notifications were also rising from other case-finding efforts.

   +80%TB notifications

6. Because of AI, about a third of urgent skin-cancer referrals at some NHS hospitals got a same-day all-clear without waiting weeks for a dermatologist.

   Evidence Coperational reportEvidence C: A company or government operational report with no independent comparison.Attribution only pathAttribution, only path: No human or conventional alternative existed in practice.Window ongoingWindow, ongoing: It began earlier, is still delivering, and has new in-window data.

   Caveat: Operational data from the vendor and trusts; at one district hospital the autonomous pathway discharged 37% of referrals and missed one basal cell carcinoma.

   25,000+cancers found; ~1/3 discharged same day

7. Because of AI-assisted decision support, 10 fewer stroke patients per 1,000 had another stroke, heart attack, or vascular death within three months.

   Evidence ArandomizedEvidence A: Randomized or cluster-randomized, with a preregistered primary endpoint.Attribution bundledAttribution, bundled: The AI shipped inside a package (tablets, protocols, crews) and the package was tested.Window pre-windowWindow, pre-window: The benefit predates the window.

   pub

   Caveat: Hospitals, not patients, were randomized, and the intervention bundled AI image analysis with guideline-based treatment prompts, so the AI's isolated contribution isn't separable; enrollment ran January 2021 to June 2023.

   26%fewer vascular events

8. Because of AI (plus tablets and pair work), junior secondary students in Sierra Leone gained about 0.26 standard deviations in math in eight weeks.

   Caveat: The control arm got neither tablets nor structured pair work, so the package was tested, not the AI; results are a Google DeepMind/Fab AI technical report, not a peer-reviewed paper.

   +0.26SD in 8 weeks

9. Because of AI, Swedish mammography screening found 29% more cancers with 44% less radiologist reading time, and 12% fewer cancers surfaced between screens.

   Evidence ArandomizedEvidence A: Randomized or cluster-randomized, with a preregistered primary endpoint.Attribution isolatedAttribution, isolated: The comparison isolates the AI's contribution: the arms differ only by the AI.Window pre-windowWindow, pre-window: The benefit predates the window.

   Caveat: The trial was designed for non-inferiority; the 12% interval-cancer reduction was not statistically significant (ratio 0.88, 95% CI 0.65–1.18, p=0.41), mortality wasn't measured, and screening took place in 2021–2022.

   29%more cancers, 44% less workload

10. Because of AI, a man with ALS has spoken with his family and kept working from home for two years through a brain implant, at up to 99% word accuracy.

    Caveat: One participant, an experimental device implanted in 2023, not commercially available; some BCIs in other ALS patients have later stopped working.

11. Because of AI, stroke patients in England were 57% more likely to get a thrombectomy and reached specialist centres 64 minutes faster.

    Caveat: Observational, not randomized; long-term outcomes couldn't be evaluated and reasons for non-use of the AI in some cases weren't captured.

12. Because of AI, 30 hearing-aid users understood far more words in heavy noise — according to the company that makes the device.

    Caveat: Both studies are Fortell-funded with a Fortell employee as first author, the control device also uses neural-network noise reduction, and the 30-person intelligibility trial was posted on the company's site rather than confirmed in a journal as of October 2026.

    31%→ 80% words understood (company trial)

13. Because of AI, Northumbrian Water stopped losing about 6.4 million litres of drinking water a day.

    Caveat: Operational report, no controlled comparison, and the saving is attributable to the detect-and-repair package; FIDO had already delivered a 37% leakage reduction across 15 target DMAs at the same utility in 2022–23.

    ~6.4ML/day saved

14. Because of AI, Oman screened 43,000 diabetics for retinopathy, flagged 12,000 for treatment, and cut specialist waiting lists by 87%.

    Caveat: Effects were modest, only one vendor saved documentation time, occasional note inaccuracies required vigilance, and the trial ran Nov 2024–Jan 2025.

    Modest burnout reduction (RCT)

16. Because of AI, 284 UCLA clinicians reported modestly lower task load and burnout from a chart summarizer — while saving no time and mostly not recommending it.
