I know only too well that computers do not and cannot work perfectly; if nothing else, extra-terrestrial gamma radiation
causes all semi-conductor devices to malfunction at random times. More manageably, devices degrade with time and their systematic error-rates increase.
Disk monitoring, once only for top-end servers, is becoming commoner in workstations, at best giving us early warning of disk failure and allowing us to replace at a convenient time before catastrophic failure interrupts day-to-day work.
The same is happening with memory (and PCI devices, ...). EDAC can deliver similar warning of impending failure on workstations as has been available on high-end servers. Apparently EDAC is not mature yet but something like it is likely to become common and in a few years hardware monitoring will be taken for granted.
