So true. Imagine the dead cats under the rugs that we entrust our lives to every day... traffic lights, onboard computers, flight navigation software. Anyone seasoned in software knows that the point is not to write bugfree software but to understand what your code is doing and how it's impacting things across the whole system. Code is very very complex and bugs can be introduced from compilers, third part libraries, yourself, system upgrades, hardware issues, etc.
