To be sure, it's not because they fail all the time, but to probabilistically address the risk that if Murphy does come knocking, consequences won't be immediately catastrophic.

We're talking about different spectrums. I'm saying that "things" in general fail all the time, not always on a single plane or flight.

Different spectrums, indeed.

I only meant to clarify that aircraft redundant systems exist because failure mode consequences would be catastrophic with unacceptably high probability otherwise; not simply because things in general fail all the time, as was asserted.

It's a subtle yet significant difference that other readers in passing may not recognize.
