Wouldn't there be a more likely explanation for an unintended bit flip than a cosmic ray? Perhaps some random hardware effect like an unintentional 'Row hammer'

Wouldn't there be a more likely explanation for an unintended bit flip than a cosmic ray? Perhaps some random hardware effect like an unintentional 'Row hammer' bit flip in other parts of the system, a very rare hardware race condition, a very unlikely quantum tunnel for the node size, etc...?
