If intelligence comes from machinery, where did the machinery come from? Other machines? Self-assemble? Or is it machines all the way down?
The machinery that gives rise to the intelligence is inherent in the physics an intellegence exists in. That means, given some particular physics, the machinery that supports the functions of intelligence will arise by self assembly.
Also, an intellegnece that exists as a result of self assembly, ie. a human, could create machinery that supports intelligence that is different from that which arises as a self assembly from the physics itself. An example of that would be an artificial intelligence program running on electronic, or optical hardware.
Isn't it rather curious that liberals just shrug their shoulders about answering where the machines, the origins of intelligence and conscious thought and organization (or anything that might help explain evolution/origins) comes from...it all "just is"...
and then turn right around and get intensely curious when they demand, "so where dod God come from"?
