> Software doesn't wear out, or degrade through use. The analogies offered to other, physical common services are nonsensical. But latent bugs are discovered at a rate that is roughly proportional to use, and for application software running under general purpose operating systems on personal computers or servers the operating systems and hardware gets updates which can cause problems for applications. That imposes a maintenance and repair burden if you want to keep applications working that is very similar to the burden imposed by wear and degradation when you want to eep some physical thing running.
