recalled from a long time ago is that when you write down ten random digits

see how special those human-generated numbers are; even when appearing

have had our number stolen.
The number of collisions may warrant solving the problem by simply
reassigning identification credentials. Think of all the other human

Identity management for credit cards is similarly obsolete; we're one of
the last places in the world where a strip of magnetic tape on a slice of
plastic can rob someone of their electronic currency. We need a better
system, ideally one that doesn't introduce new problems for the
