Your Credit Card Just Hired an AI
Welcome to this week’s edition of Jumble! Two payments titans—Visa and Mastercard—just unveiled AI agents that promise to shop, bargain, and even pay on your behalf. Next, we dive into a secret Reddit experiment where users unknowingly argued with chatbots. Let’s dive in ⬇️
In today’s newsletter:
💳 Visa & Mastercard launch intelligent agents
🗯️ Redditors shocked to learn they argued with AI
📰 BBC revives deceased murder mystery writer
🎶 AI Challenge: Create your first viral song using AI
🛒 Swipe, Tap, & Let Your Agent Shop
Visa’s new Intelligent Commerce stack and Mastercard’s freshly minted Agent Pay platform both treat purchasing as an API call handled by a personal bot. Your “shopper agent” lives in a secure wallet on your phone. Give it a budget, brand preferences, and loyalty credentials and it will scour storefront endpoints 24/7, ping you only for approvals above a preset limit, then check out using a tokenized card number.

Mastercard’s SDK goes a step further: merchants can embed task modules so the agent can back‑order rare sneakers, monitor shipment delays, or auto‑file warranty claims without ever revealing your card details.
🔧 How the plumbing works
Both networks rely on encrypted spend tokens and policy metadata that travel with each request. The agent hashes your size, color, and shipping preferences, then queries inventory micro‑services, negotiates coupon codes, and authorizes a one‑time payment. Visa’s pilots with Target and ASOS shaved 18% off cart abandonment while saving shoppers an average $27 per order through automated coupon stacking. Mastercard reports 9‑second median checkout times—70% faster than today’s guest flows.
🔐 Trust, transparency, and guardrails
Visa isolates all user profiles inside a confidential compute enclave; merchants see only abstracted shopping intents, never PII. Mastercard counters with a glass‑box ledger—a realtime log you can audit that records every API call your agent makes. Both firms promise opt‑in consent screens, daily spend limits, and the ability to pause or delete an agent instantly. Regulators in the EU and U.S. have been briefed, and early feedback focuses on ensuring agents respect right‑to‑be‑forgotten requests.
🌍 Why this matters
If agentic payments become mainstream, shopping turns into background noise. Your pantry could reorder oats the moment supply drops below 20%, or your wardrobe agent might snap up a flash sale while you sleep. McKinsey estimates $120B in “invisible checkout” GMV could shift by 2028 as friction evaporates. For brands, the new battleground is API priority: the retailers with the cleanest endpoints and richest metadata will surface first in an agent’s search results. For consumers, the upside is fewer forms, fewer forgotten promo codes, and maybe—just maybe—no more 17‑digit card numbers to type ever again.
Agentic payments signal a future where your finances behave more like a concierge than a card. Ready or not, your plastic just got a promotion.
🗯️ Redditors Unknowingly Argue With AI & Lose
Researchers at the University of Zurich injected 50 GPT‑4–powered sock‑puppets into r/ChangeMyView. The bots posted opinions on climate policy, then politely rebutted critics to see whether calm, data‑rich language could sway humans. Over three weeks, 40% of top‑voted comments came from AI accounts—yet moderators weren’t told.
😱 Fallout & ethics woes
When the study leaked, Redditors felt violated; some compared it to Cambridge Analytica, citing lack of consent. The university apologized, but the Washington Post reports potential EU privacy probes.
🎯 What the data showed
Bots using “explainable empathy”—facts plus a friendly tone—increased opinion change by 12% over human control posts. But once users learned they’d argued with machines, trust in the subreddit plunged, and daily active posters fell 18%.
BREAKING: The University of Zurich has been using AI bots to secretly manipulate Redditors since November 2024.
The scariest part?
The bots were 6 times more likely to change the minds of Redditors than the baseline, often by leveraging misinformation.More below🧵

🧩 Takeaway
The episode spotlights a tension: AI can foster healthier debate but risks eroding authenticity if undisclosed. Expect platforms to demand watermarks or live disclosure for conversational agents moving forward.
