It seems that a very large piece of something divides into a bunch of small pieces of something. These small pieces of something then get replicated somewhere that has some code that makes more pieces of something that is different. These new pieces of something combine into more pieces of something that join the collection of all the pieces of something that cycle through this process for, like, forever. Sometimes, some of these pieces of something just disappear when they fail to enhance the collective good of all the pieces of something. But their existence seems to influence the cycle for, like, forever. Sometimes, the code itself flows through this cycle for, like, forever.
