Edge Question 2009: "What Will Change Everything?" http://www.edge.org/q2009/q09_9.html#smolin What do we think about this? Smolin seems to disagree with most of what we are on about on this list. My mind remains open in all directions, particularly as Smolin appears to be enjoying substan

Hal, I have entertained quite similar musings some time ago, and this led me to a position I called "naive materialism" NMAT some time ago on this list - that causality does not matter, and consciousness would supervene on the material states directly - and both backward and forward versions

It seems to me that your reasoning illustrates well the problems with physical supervenience and physicalism, and perhaps ASSA. In any case the Universal Dovetailer generates all such gaz universes generating the Boltzmann brains. Now the probability that you are implemented by a particula
