The ability to form an arithmetic compression is one definition of intelligence.

Even if the brain were continuous rather than discrete, there is no limit to how accurately its behavior could be simulated.

A machine can't evolve for it's own purposes. A-life can and does.

A lump of coal and a glass of water aren't alive until they are organized appropriately, what makes them "organic" is a matter of their organization and relationships between each other. So long as this organization and the relationships are preserved, the pattern and its complexity are preserved. > The computer has no high level complexity, I think that is an absurd statement.

These are all discrete particles with understandable properties and known relations between them. Thus these same relations can be replicated in any computer so that burning may take place. Also, are you sure you have never heard of Searle?

I think you need to "see" (having qualia) in order to see. In other words, Zombies are not possible.
