I think the amount of textual user data in memory is dwarfed by various kinds of program data (pointers, metadata, static strings, libraries, etc) as well as image data. It seems pretty likely that bit flips could result in a crash once in a while or could have no effect at all if the bit flip is in some rarely used piece of an executable loaded in memory. For example, would anyone notice that a letter in an error message string is corrupted? So errors may be happening at the rate that researchers report, but with only a tiny fraction of them happening in user data where they will be noticed.
