I have heard Victor Wooten use this anology.
DDwilkins is on point with his example.
I think of the fretboard like the Keyboard I am using to type with right now. When I took typing classes in the 7th grade I had to look at my fingers to type.
but by the 8th grade, I could effectively type 35 words a minute without looking down at the keyboard. Now Many years later, I can type without looking at the keys, and whats more, I can type without really thinking what I am typing. The moment something hits my mind, my fingers automatically go to the position on the keyboard to create words.
While these are great examples, and hold much truth. Music is a bit different, because you add tonalities, to expression. If I say "Hello" Low, or high, Mono-tone or with many voice fluctiations. Its all discernable. With music we fully rely on tones to verify differences. The English language doesn't rely on tonalities so these examples don't really jump out to us.
