It is my dream that one day you will write an entire post without
once referring to some fossilized ancient Greek. I have a dream!

Another explanation is you made a blunder in step 3, a blunder so
severe I suspected you literally didn't even know what you were
arguing for. Subsequent conversation has only increased my suspicion.
Write a text. Up to now, you convince zero person. Step 3 is
kindergarden level.

That's easy, all I have to do is reach for my $2.99 calculator
punch in 2+2 and voila, I have a existence proof that
matter that obeys the laws of physics can perform a
calculation. Now I want you to do the same thing using NOTHING but
pure arithmetic.

Because atoms are generic. One atom of the same element is as good
as another so the important thing that needs to be preserved is
information on how those atoms are arranged, it's the only thing
that makes me different from you. So replacing one carbon atom in my
brain with another carbon atom is of no consequence to me, even
replacing a carbon atom with a silicon atom is OK as long as it
processes information in the same way. If it does that then it's
still me.
And information is not some vague abstract quality, information is
physical, information has entropy, processing information causes
heat, and storing information always involves changing the PHYSICAL
state of something. Information is as close as you can get to the
traditional religious concept of the soul and still remain within
the scientific method.
