This is a pretty big claim which seems to imply this is much more common than expected, but there's no real information here and the numbers don't even stack up:

> That's one crash every twenty potentially caused by bad/flaky memory, it's huge! And because it's a conservative heuristic we're underestimating the real number, it's probably going to be at least twice as much.

So the data actually only supports 5% being caused by bitflips, then there's a magic multiple of 2? Come on. Let alone this conservative heuristic that is never explained - what is it doing that makes him so certain that it can never be wrong, and yet also detects these at this rate?
