<off-topic> <IANADBExpert> Interesting theory, but seems kind of wrong. Wouldn't the time to look up or fail be tied to the complexity of how the key space is populated? In any case, it seems like the time to succeed or fail will usually be about the same, since you'll try to access the value for a key and either find something there or fail.

If you get a request, you will have to respond in any case.
I have a theory about data-base lookups--finding something is always faster than not finding anything, unless you are using a human brain.
(A human brain can respond "I don't know that" without an inventory of everything it does know.)
(That may be to only truly unique thing about humans. And no, I have not kept up with neural networks work.)
