For most individual needs unguessable is sufficient.  Raw images of
aquarium bubbles and fish, lava lamps, a tree of leaves outside is quite
unguessable by the world and thus very useful for an individual.  A chip
design replicated in the millions nearly billions each can from shear
numbers  can have its flaws exposed as can operating system software that
depends on that hardware.

Casinos and lotteries need TRNG that are also unguessable. Flaws on the
draw or quick-pick generator could be costly.
