  1. Cả hai vụ đều là “người thông minh làm việc hợp lý” nhưng hệ thống hoạt động đúng thiết kế sai lầm:
    🚀 Mars Climate Orbiter (1999) mất vì một nhóm dùng đơn vị Imperial, nhóm còn lại dùng Metric.
    🏦 Citibank ($500 triệu, 2020) lỗi thanh toán vì nhãn UI không rõ ràng, chuyển tiền gốc thành lãi.

    Thất bại không do độ phức tạp, mà do “nghĩa” chỉ tồn tại trong đầu người, tạo “technical debt” khổng lồ.

  2. From the looks of it, the #NATS meltdown and the development style of Austrian software company #Frequentis will provide an excellent example for programming teachers for years. It might even surpass #ariane5 floating point, NASA's #MarsClimateOrbiter's meter vs feet parachute and #Therac25
