>For example, if you wanted to chill your beverage, dropping an ice-cubed sized computer running the algorithmic emulation of an of an ice cube melting will not chill your drink no matter how perfect your emulation is, while a physical ice cube can perform that physical state change of your drink. Interestingly enough, this may not be entirely true. There are some fundamental relationships between computation, information, and entropy, that, in the limit of computational and representational perfection, probably would require exactly the amount of input energy as the ice-cube itself would to melt. Now, you might argue that this is a pedantic attack on your argument. It's not though. The real point is that the laws of physics often seem to have grander symmetries and transformation laws than observable at first glance, and the universe has very clever ways of enforcing these symmetries in what appear to be very different contexts, but are indicative of less intuitive symmetry laws.
