Answer: True
Explanation: Despite increasingly advanced and proactive technologies in development and use, running simulations with the aim of identifying every failure mode in a technology or to test technologies under every conceivable circumstance is neither possible nor practical. This is because an unpleasant or unexpected event might happen or exist in the future irrespective of our anticipating most likely problems. Going forward, without waste of time and needed resources, it is quite effective to solve eventualities as they arise by making modifications to existing technologies.
