Software Wear-out and Design Philosophy

publish date: 2026/10/04 04:25:26.553689 UTC

Unlike physical hardware components, software does not suffer from physical wear and tear over time. Why do some engineers use this fact to argue against software redundancy and diversity?

Because redundant software automatically prevents human errors during system specification.

Because software does not physically wear out like hardware, making physical component aging irrelevant to software bugs.

Because simple software eliminates the need for redundant hardware components.

Because financial savings from avoiding complex redundant software can be reinvested into rigorous verification and validation.
