No, I stand by what I said. If there's a bug, then that software is not
correctly-working (even if it seems to be).

The analogy for hardware would be a marginal timing problem (wher,
peerhaps, every 10 years 2 signals arrive effetively in the wrong order).
That's a mis-design, it's not working correctly.

But correnctly-working software carries on working. Hardware on the other
hand can stop workin if a component fails.
