Yes, I already have a couple of Raspberry Pi, but I had to get one of the new Raspberry Pi 2 (model B), to check out its increased processing power with OpenCV and image processing.

This basically means that the state of “confusion” of a system will increase in time. It explains why your house is such a mess if you don’t do anything about it! And yet, out of this chaos, life emerged. Isn’t that amazing? Life is about information, structure, organization… Exactly the opposite of the second law of thermodynamics.

So these replicator machines were organizing materials and replicating themselves. They were saving information about their structure for the replication process. They didn’t care about the second law of thermodynamics.
