    Yes, but also having industrial equipment break because a bit flipped and that caused a sacrificial mechanical safeguard to have to do it job would lead to costly downtime and equipment replacement. So, it's a false economy to say you don't need ECC because you have mechanical safeguards to fall back on.

    Well, yes, if the hardware is under operating environmental range. If it's over 250F or 120C, the chips start bubbling.
    We've establish you need a mechanical safeguard, but I would hope an industrial controller would also enter thermal shutdown, if it exceeded its operating temperature range.

    Something like a Raspberry Pi 4 will reduce its clock speed, when it overheats. That was a big issue, when it first launched, due to the performance impact. But that shows us that not only does it have built-in temperature monitoring, but it also has active clock-throttling (and probably thermal shutdown, I presume).

    Then they will fail because the chip will fall off from the solder bubbling.
    Also, before they get nearly that hot, you might find that the software can't meet realtime guarantees, due to the reduced clock speed. That's another scenario under which it might voluntarily shutdown.
