Recommendation Engines and Infinite Monkey Theorem


"The infinite monkey theorem states that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time will almost surely type or create a particular chosen text, such as the complete works of William Shakespeare."

In 2003, Plymouth University Researchers left six monkeys and a computer in a cage,for 4 weeks. All the monkeys could come up with, were long sequences of A.

The experiment probably was "fun" and not scientific, because the concepts of time, infinity and probability are in measures beyond the average human experience.

Even though, there are billions of people in the Planet, the number of people who bought, "The world is flat" is probably in the order of thousands, which is a small number.

The law of large numbers does not scale down very well. This is why the notions of collaborative filtering, i.e., boiling the consumption patterns of all users into one universal set, does not work.

However, my hypothesis is that: "a Monkey randomly curating tweets for an infinite amount of time will almost surely link to Hamlet".
