That sounds like eliminative materialism. It is a bit like saying that
the movement of the car down the road *IS* the combustion of fuel in
the cylinders, transmission of power to the wheels, and all the other
lower level phenomena that make up the car.

You change your mind because all the components of your brain change
configuration. If this did not happen, your mind could not change. The
mind is the higher level phenomenon. The analogy is as above with the
car: it drives down the road because of all the mechanics functioning
in a particular way, and you could say that driving down the road is
equivalent to the mechanics functioning in a particular way.

You completely misunderstand these experiments. Please read about
excitable cells before commenting further. The following online
articles seem quite good. The third is about spontaneous neuronal

The laws of nature are broad enough to determine everything everywhere
that has happened and will happen.

The question was about two identical computers, one made in a factory,
the other assembled with fantastic luck from raw materials moving
about randomly. Will there be any difference in the functioning or
consciousness (or lack of it) of the two computers?

So how would a human put together by molecular assembly machines using
the template of a regular human be different from the regular human in
either behaviour or consciousness?
