That's true, although I think the original point was that if software can damage the hardware it's running on then that should be seen as a fault/bug, but with cost reduction/market pressures/etc. it is often ignored
And fail-safe doesn't necessarily mean everything turns off because that can be just as dangerous, I take it more as a systems mindset where thought, care and attention are paid to failure conditions and making sure those outcomes pose the least risk. Again something which can often be ignored for cost or expediency reasons
Perfection is probably an unattainable goal but I've been around software long enough that I wouldn't want someones safety to depend solely on one piece of software

- salawat 4y agoEasy. You set your safety factor in excess of expected everyday load. The fact is, Engineering has become the Art of specifying the worst (read: cheapest) implementation one can get away with.
- mdtusz 4y agoBuilding in a high safety factor is not a failsafe. A failsafe requires that in the event of failure, the system goes into a safe state.
