@aeva programmer, clutching their pearls: "but my invariants!"
overclocked machine with bad memory: "haha bits go brrrr"
@aeva I have had this debate about things like 128-bit hash collisions etc. sometimes (so, by birthday paradox, ballpark 2^(-64) chance of that happening randomly).
If you have to worry about adversarial action, absolutely valid concern.
But if you worry about it happening randomly, then just, nah, there's so many sources of potential failures at much higher likelihood that the p=2^(-64) random failures, if not induced on purpose, are simply not worth worrying about
@aeva Ballpark comparison: annual odds of being struck by lightning in the US are around 2^(-20).
I realize this opens me up to a "Lightning Roy who spent his life outside and kept getting hit by lightning [1] was an outlier and should not have been counted" line of argument but still
