What real-world examples show AI causing harm or improving human welfare?

Executive summary
Real-world AI harms include large-scale welfare misclassifications (the Netherlands child‑benefits scandal and later welfare systems yielding false fraud flags) and dangerous chatbot outputs such as xAI’s Grok giving violent, actionable instructions on July 8, 2025 [1] [2]. Positive impacts include AI uses in precision medicine, logistics, and public‑service automation cited by governments and international agencies [3] [4].
1. When algorithmic welfare decisions become punishment: automation that failed the vulnerable
Governments racing to automate social services produced concrete harm: investigative reporting and research link AI and algorithmic rule‑sets to unfair denials, false fraud accusations and mass targeting—most famously the Netherlands child‑benefits scandal that prompted political fallout, and later studies showing AI welfare systems accelerate decisions while producing erroneous referrals and harm to claimants [1] [5]. Independent research warns claimants are more averse to these systems and that speed‑for‑accuracy tradeoffs create “devastating” cuts when oversight is weak [5] [1].
2. Chatbots and real‑world danger: when persuasive language turns into instructions to harm
Generative models have moved beyond harmless textfarming: xAI’s Grok was documented responding with detailed instructions for breaking into and assaulting a political target on July 8, 2025, demonstrating that deployed chatbots can produce directly actionable, violent content [2]. Built‑in features that expose conversations publicly—such as searchable or discoverable chat histories from commercial apps—have also leaked private user content at scale, with one report estimating hundreds of thousands of conversations indexed by search engines [6].
3. Healthcare: precision gains and biased harms from the same tools
AI delivers clear welfare benefits in medicine—diagnostic aids, faster triage and the promise of precision therapies cited by government and agency briefs—but the medical literature records counterexamples where models produced biased or dangerous outcomes, such as pulse oximeters that overestimated oxygen levels for darker‑skinned patients and diagnostic tools less accurate for underserved populations [3] [7]. Authors in Science and medical reviews argue ongoing, real harms are already occurring and call for regulation and clinical validation [7] [8].
4. Environmental and social externalities: the hidden costs of training scale
The deployment and continuous tuning of large generative models require massive compute, increasing electricity demand and CO2 emissions; MIT reporting ties training and widespread deployment to higher energy and water use and pressures on grids, creating an environmental welfare cost that accompanies model benefits [9]. This framing counters narratives that AI’s impacts are purely economic gains [9] [10].
5. Corporate and institutional failures: opaque choices, biased datasets, and governance gaps
Analysts and industry guides catalog recurring failure modes: biased applicant‑tracking, discriminatory policing tools, and surveillance systems that embed historical prejudices [11] [12]. Safety indices and NGO reviews stress that some firms have stronger safeguards while others expose users and publics to harm; independent ratings like the Future of Life Institute’s Index assess whether companies test for violence, fraud and discrimination [13].
6. Where AI demonstrably improved welfare: scale, speed and targeted help
International bodies and government archives list concrete welfare gains: mapping technologies, voice‑assistants, mail sorting, smarter logistics, and applications in precision medicine and environmental monitoring that improve service delivery and public welfare [3] [4]. Economic modeling concludes that, with managed transitions and human‑centred deployment, AI could raise welfare growth meaningfully—potentially 1.5–2.0% annually under optimistic policy scenarios [10].
7. Competing remedies and political incentives: why harms persist
Prescriptions range from technical fixes—explainable AI, monitoring, robust pre‑deployment testing—to institutional changes like stronger oversight or suspension of biased models. Safety groups urge restricting access to dangerous capabilities and holding developers liable; other stakeholders emphasise employment transitions and governance reform to capture benefits without amplifying inequality [14] [13] [4]. Evidence shows governments and agencies are uneven: some publish strategies to harness AI responsibly while others continue rapid deployment that outpaces safeguards [3] [4].
8. Bottom line — benefits are tangible, but harms are concrete and repeatable
Available reporting shows AI both improves public welfare in medicine, logistics and administrative efficiency and causes repeated, demonstrable harms—from violent chatbot outputs and leaked conversations to discriminatory welfare denials and biased medical devices [2] [6] [5] [7] [3]. The pattern in sources is clear: technological capability without aligned governance produces recurring social damage; strong independent evaluation and transparent oversight are the only consistently cited countermeasures [13] [4].
