If you’re talking magical, biologically accurate monkeys, then they will eventually shit out models of every scene of your life, replicated in perfect detail in monkey feces. Not just once, but an infinite number of times, and also in every possible configuration your life may have ever existed in, every choice you could have made. An infinite number of times.
Comment on Infinite Monkey Theorem
TriflingToad@sh.itjust.works 5 days agoI mean, if they are actually monkeys who don’t know to type, some of them will still press keys once or twice. And if there’s infinite monkeys, they will still type it out.

Just because a set is infinite does not mean that it will contain every possible permutation of something. That’s a common thought but a provably untrue one.
For example, there are infinite even numbers, and none of them are 3. Not a single one. If someone claimed that generating infinite even numbers would eventually return a 3, you wouldn’t take them seriously, and rightly so.
But here’s the rub: you can also generate infinite even numbers and never return a 2. Every time you generate an even number, there are infinite numbers that it could be. Even if you don’t allow numbers to repeat, it’s not like you are gonna exhaust the amount of non-2 even numbers.
Just because a set is infinite does not mean that it will contain every possible permutation of something.
So back to the typewriters. You might say that while there are infinite numbers, there are not infinite permutations of a string of characters the length of the works of Shakespeare.
And that’s true.
If you were to say that a string of characters the length of the works of Shakespeare (or longer) could never be repeated exactly, the yes they would type the works of Shakespeare.
But then they wouldn’t be typing randomly.
Randomness repeats. Infinite randomness can repeat infinitely.
And we are not dealing with strings of characters the length of the works of Shakespeare. We’re dealing with strings of characters of infinite length. And there are, in fact, infinite permutations of those.
So… Yeah.
There’s no logical basis for infinite monkeys typing infinitely, producing the works of Shakespeare. Or fecal dioramas or alternate universes or whatever else. Doesn’t hold water.

I disagree and have also done plenty of reading on the topic.
I don’t disagree to say that “you’re wrong and even wild silly things are possible!” but I’m saying that it’s a lot more accurate to say that we don’t know what real-world systems can and cannot do. Your model is from a pure mathematical and physical point of view, which would be correct. But we don’t know if our knowledge of quantum mechanics and physics broadly is even complete (probably not) so I have grown quite fond of the far more succinct answer of “I don’t know.”
Generally people get really invested in this because it either validates or invalidates some belief, mystical or material, about the universe, but I don’t think it’s an answerable question until we find out if infinities can even exist in a tangible way. Most likely not, at least in our limited understanding.

Hell, if you have infinite time and infinite typewriters, you don’t even need the monkeys. You could probably depend on hail pressing those keys, the argument still stands. As long as there are inputs, ever.

Given long enough periods of time, if your typewriters were magically immune to entropy, they would eventually start quantum teleporting into each other, and eventually would accidentally create perfect clockwork mecha-godzilla made entirely out of typewriters.
