I suspect he doesn't share the same understanding of the "intended
uses" of bash's $RANDOM as the rest of us.

It's meant for displaying a random wallpaper image from a directory,
or for playing a random audio file from a directory.  Or for playing a
number guessing game with a 6 year old.

It is emphatically NOT for generating passwords.
