Why use ECC?
I just want to be clear that in the original referenced article, I am not anti-ECC per se, I just found myself caught in the massive cognitive dissonance between "you must have ECC in all your computers otherwise they will constantly and silently corrupt your data + crash" and "statistically speaking, most computers in the world do not use ECC". How can both of these things be true?<p>The argument for ECC is credible (I personally think rowhammer is the best example of this actually mattering, but ironically a) you can rowhammer ECC memory just fine and b) DDR4 has hardware features to mitigate rowhammer -- which shows how quickly things are changing), but it also seems to hinge on whether you have hundreds to thousands of computers all working together, e.g. the positive effects of ECC only seem to matter enough statistically at a _very_ large scale.
