Makes me think of the classic video of a white blood cell chasing a bacterium. You can sense the frantic desperation of the bacterium as it tries to get away from something monstrous that will inevitably swallow it whole. [this video]

This is because HIV is a brilliantly designed virus (of course it evolved, it's not designed. I don't know a better way to say this though). It's a third-generation retrovirus, meaning it defeats internal cell safeguards in a very clever way, meaning that if one cell of a few types comes into contact with ~10 virus particles, you effectively have AIDS. For the flu we're talking hundreds of cells needing to be in contact with thousands of virus particles. It evades being a target for vaccination by using internal body networks to transmit itself as opposed to the blood. The immune system inside our bodies has a sort of chemical protocol for one cell to exchange data with another. One cell app

In my opinion, it's not. Natural intelligence is another way of saying that dynamics and interactions of millions of neurons in our brain is too complicated for us to understand. Our brain is just a complex machine, and the complexity at the level of its individual components is based on very fundamental laws of physics and chemistry. In that sense, you bring up an excellent question. I don't think there exists any unique "natural intelligence" which Hofstadter in the linked article is referring to. Watson is only different from "natural intelligence" in terms of complexity. Conway's Game of Life can perhaps be used as an analogy here. The uninitiated is likely to assume a very complex sourc
