FinAgent: When AI Starts Shopping for Your Groceries (and Your Health)

Opening — Why this matters now Inflation doesn’t negotiate, food prices don’t stay put, and household budgets—especially middle‑income ones—are asked to perform daily miracles. Most digital tools respond politely after the damage is done: expense trackers explain where money went, diet apps scold what you ate. What they rarely do is coordinate. This paper proposes FinAgent, an agentic AI system that does something radical by modern standards: it plans ahead, adapts continuously, and treats nutrition and money as the same optimization problem. ...

Personas, Panels, and the Illusion of Free A/B Tests

Opening — Why this matters now Everyone wants cheaper A/B tests. Preferably ones that run overnight, don’t require legal approval, and don’t involve persuading an ops team that this experiment definitely won’t break production. LLM-based persona simulation looks like the answer. Replace humans with synthetic evaluators, aggregate their responses, and voilà—instant feedback loops. Faster iteration, lower cost, infinite scale. What could possibly go wrong? ...

Reading the Room? Apparently Not: When LLMs Miss Intent

Opening — Why this matters now Large Language Models are increasingly deployed in places where misunderstanding intent is not a harmless inconvenience, but a real risk. Mental‑health support, crisis hotlines, education, customer service, even compliance tooling—these systems are now expected to “understand” users well enough to respond safely. The uncomfortable reality: they don’t. The paper behind this article demonstrates something the AI safety community has been reluctant to confront head‑on: modern LLMs are remarkably good at sounding empathetic while being structurally incapable of grasping what users are actually trying to do. Worse, recent “reasoning‑enabled” models often amplify this failure instead of correcting it. fileciteturn0file0 ...

RoboSafe: When Robots Need a Conscience (That Actually Runs)

Opening — Why this matters now Embodied AI has quietly crossed a dangerous threshold. Vision‑language models no longer just talk about actions — they execute them. In kitchens, labs, warehouses, and increasingly public spaces, agents now translate natural language into physical force. The problem is not that they misunderstand instructions. The problem is that they understand them too literally, too confidently, and without an internal sense of consequence. ...

Traffic, but Make It Agentic: When Simulators Learn to Think

Opening — Why this matters now Traffic simulation has always promised more than it delivers. City planners, transport researchers, and policymakers are told that with the right simulator, congestion can be eased, emissions reduced, and infrastructure decisions made rationally. In practice, most simulators demand deep domain expertise, rigid workflows, and a tolerance for configuration pain that few real-world users possess. ...

When 100% Sensitivity Isn’t Safety: How LLMs Fail in Real Clinical Work

Opening — Why this matters now Healthcare AI has entered its most dangerous phase: the era where models look good enough to trust. Clinician‑level benchmark scores are routinely advertised, pilots are quietly expanding, and decision‑support tools are inching closer to unsupervised use. Yet beneath the reassuring metrics lies an uncomfortable truth — high accuracy does not equal safe reasoning. ...

When More Explanation Hurts: The Early‑Stopping Paradox of Agentic XAI

Opening — Why this matters now We keep telling ourselves a comforting story: if an AI explanation isn’t good enough, just refine it. Add another round. Add another chart. Add another paragraph. Surely clarity is a monotonic function of effort. This paper politely demolishes that belief. As agentic AI systems—LLMs that reason, generate code, analyze results, and then revise themselves—move from demos into decision‑support tools, explanation quality becomes a first‑order risk. Not model accuracy. Not latency. Explanation quality. Especially when the audience is human, busy, and allergic to verbose nonsense. ...

Agents All the Way Down: When Science Becomes Executable

Opening — Why this matters now For years, AI for Science has celebrated isolated breakthroughs: a protein folded faster, a material screened earlier, a simulation accelerated. Impressive—yet strangely unsatisfying. Real science does not happen in single model calls. It unfolds across reading, computing, experimentation, validation, revision, and institutional memory. The uncomfortable truth is this: as AI accelerates scientific output, it is quietly breaking the human systems meant to verify it. Peer review strains. Reproducibility weakens. “It worked once” becomes the dominant success metric. ...

Teaching Has a Poker Face: Why Teacher Emotion Needs Its Own AI

Opening — Why this matters now AI has become remarkably good at reading emotions—just not the kind that actually matter in classrooms. Most sentiment models are trained on people being honest with their feelings: tweets, movie reviews, reaction videos. Teachers, unfortunately for the models, are professionals. They perform. They regulate. They smile through frustration and project enthusiasm on command. As a result, generic sentiment analysis treats classrooms as emotionally flat—or worse, mislabels them entirely. ...

Think Before You Beam: When AI Learns to Plan Like a Physicist

Opening — Why this matters now Automation in healthcare has a credibility problem. Not because it performs poorly—but because it rarely explains why it does what it does. In high-stakes domains like radiation oncology, that opacity isn’t an inconvenience; it’s a blocker. Regulators demand traceability. Clinicians demand trust. And black-box optimization, however accurate, keeps failing both. ...
