I am not sure if I correctly understood your point. On one dimension, you are basically hinting at another anecdote that proves my point: hardware failure (specifically bit flip in non-ECC memory) is pretty much guaranteed to happen at scale, but people are mostly okay with absorbing that risk. I feel you are overselling the hardware reliability story. For sure, we can build less reliable systems out of reliable components. That goes without saying, and no, that's definitely not software specific. Almost by default most composite systems are less reliable than their primitives (simple example would be nailing two pieces of wood) unless specific care is taken to build in those guardrails or redundancies. The point, however, is it is possible, and there is a vast precedent for it.
