The original headline is: "The 10 Most Expensive Software Failures in History — and the One Thing They Share"

Short summary

The most expensive software failures in history — from Knight Capital's $440M loss in 45 minutes to Boeing 737 MAX's 346 deaths — share a common pattern: no adversary, no alarm, one change propagating everywhere at once. These silent, correlated, self-inflicted failures are exactly the risk autonomous AI agents are poised to recreate at scale. The article catalogs ten disasters with primary-source figures, drawing the lesson that systems trusted past their evidence cause the most damage.

• •Ten historic software failures (Knight Capital, CrowdStrike, Boeing MCAS, UK Post Office Horizon, Zillow, Ariane 5) cost billions with no attacker involved
• •Common pattern: silent, correlated, self-inflicted failures where systems acted confidently on bad inputs with no alarms
• •Core warning: autonomous AI agents will recreate this failure mode — automated systems executing mistakes faster than humans can intervene
