Global IT outage shows dangers of cashless society, campaigners say

Infrastructure fragility & redundancy

• Several comments argue all infrastructure is inherently fragile and subject to entropy; others counter that some systems (e.g., modern power grids) are measurably more reliable than in past decades.
• Debate over whether we must accept fragility vs. can engineer robust redundancy, with calls for explicit plan B/C/D for critical services.
• Historical structures (Roman concrete, cathedrals, pyramids) are cited both as evidence of robustness and as survivor bias.
• A large solar flare’s impact is disputed: some say it would only kill power grids, not microelectronics, but even that would be catastrophic.

Cash vs. cashless as resilience

• Many see the outage as proof societies need cash as a fallback when electronic payments fail.
• Others argue cash isn’t a guaranteed backup: ATMs and bank branches also depend on IT (often Windows) and may fail too; cash only helps if people pre‑withdraw and hold reserves.
• Some insist there is “no going back” because cash is inconvenient, runs out, and electronic payments are too entrenched.

Legal and practical acceptance of cash

• Wide variation by country/region:
  • Some places (e.g., parts of Norway, Seattle) have many “card only” businesses.
  • Others (e.g., Italy, some U.S. states like Oregon, Massachusetts in theory) legally require acceptance of cash, with various exceptions.
• Motivations for card‑only: reduce fees/overhead, staff theft, robbery risk, and to collect more customer data.
• Motivations for cash‑only: avoid card fees, avoid receipts/tax scrutiny, or lack of connectivity.

Privacy, freedom, and surveillance

• Strong thread arguing cash is uniquely private: no centralized transaction log, less amenable to profiling or censorship.
• Counterpoints note serial numbers, ATMs, and CCTV reduce anonymity, but others reply this is still far less centralized and searchable than card data.

Digital payments, monoculture, and testing

• Outage is seen as a monoculture failure: many critical systems tied to Windows and a single security vendor.
• Some note core card networks held up; failures clustered at POS/endpoint level.
• Old manual card imprinters once provided offline redundancy but largely disappeared due to fraud and card design changes.
• There is criticism of blind auto‑updates and underinvestment in rigorous testing for widely deployed security software.

Currency design: fiat, gold, crypto, barter

• Jokes about going back to eggs‑for‑beer highlight a serious discussion about inflation, central banking, and store‑of‑value.
• Some propose gold or crypto as non‑inflationary, non‑spoiling, decentralized alternatives.
• Others argue stable currencies require managed supply and some inflation to prevent hoarding; point to high volatility and poor pricing usability of gold/Bitcoin.
• Bitcoin’s technical limits (throughput, speed, environmental impact) and the need for additional layers (e.g., Lightning) are raised; those extra layers risk recreating bank‑like intermediaries.

Corporate incentives, compliance, and liability

• Several comments link systemic brittleness to misaligned incentives: executives and boards rarely face personal liability for large‑scale failures.
• Debate over limited liability: some defend it as necessary for entrepreneurship; others suggest scaling down protections for very large firms.
• Compliance regimes (e.g., NIST, STIGs) are cited as drivers for ubiquitous endpoint security tools, including on Linux, even when their real security value is questioned.
• Market pressure for low cost and speed to market is seen as driving under‑tested, over‑centralized solutions.

Cultural shifts & regional patterns

• Sweden is mentioned as a high‑online‑payments country whose central bank is now working to explicitly protect cash.
• Some recall that much of the tech world, including high‑profile companies, strongly pushed for a near‑cashless society a decade ago; recent outages are viewed as a corrective to that enthusiasm.
