Assume that the universe is a computer. Therefore, everything that happens is the result of some computation done naturally at all levels.
If this assumption is reasonable, what are our brains? I would like to say that our brains are biological computers implemented over the universal computer. It is unable to work faster than speed of light and to do computations that are not possible in this universe. Also, if some component is replaced at the universal computer layer, e.g. some chemical substance in the brain, our hardware (brain) needs to adapt itself to it. Sometimes, it is unable to do that, e.g. Alzheimer's desease. Sometimes it regenerates. And there is also the brain plasticity.
Continuing, what about our software? I guess it runs over the brain. ;-) It is capable to explore brain redundancies. So what is consciousness? Is consciousness the ability to perceive our internal computations as well as part of the surrounding computations done by our universe around us? Is our consciousness limited by this ability to detect universe computations?
I posted this on a Linkedin community about Computing and Philosophy. Strong criticisms from entropy and other aspects.
