In the 2010 era of RAM density, random bit flips were really uncommon. I worked with over a thousand systems which would report ECC errors when they happen and the only memorable events at all were actual DIMM failures.
Also, around 1999-2000, Sun blamed cosmic rays for bit flips for random crashes with their UltraSPARC II CPU modules.

Yep, hardware failures, electrical glitches, EM interference... All things that actually happen to actual people every single day in truly enormous numbers.
It ain't cosmic rays, but the consequences are still flipped bits.
