Your car gets you around town quickly enough and at tolerable cost.
However, with probability 2^-21, on any given day, you will die in
a car accident.  With a Volvo and careful driving, you might
conceivably get that down to 2^-31.  With probability perhaps
2^-39, your whole family will die with you.

If this seems gruesome, a nuclear-exploding dishwasher is more so.

So, if you're a billion billion billion times more worried about a
hash collision than about your whole family dying in a car collision,
then maybe monotone isn't for you.
