Like the infinite monkeys typing Shakespeare, but with audio instead.
If there was a program that created a series of sounds at random intervals, pitches, amplitudes, etc., how long would it take to produce an output that sounds like music, some sort of recognisable recording (e.g. a bell ring, a dog barking), or perhaps even a human voice?
Yes, in a span of now to infinity. It could take 13 weeks, or maybe 13 billion years. Maybe you’ve been clicking the button until entropy has leveled out, the final book of your life being the one written at the death of the universe. But your story hasn’t ended yet. You’re now a branch that needs to be pruned, existing in a space that doesn’t exist in any way we could ever conceive of…clicking the button. You got your hopes up 34 quadrillion years ago, but the final word was “their” instead of “there”. You’ll get their.
