The myth of computer consciousnesss and intelligence
People have been trying to create perpetual motion machines
for centuries, but nobody has succeeded, I believe because
of energy losses. The problem with making computers
truly intelligent I believe is also impossible, because
the final stage of perception must be subjective (free of symbols),
not objective (described in symbols). In particular,
Computers can only deal with descriptive knowledge (symbols),
which is third person singular, hence, not personal and private,
not conscious.
The results and the process itself are publicly avalable (as
code) and communicable.
Only living creatures-- even a gnat--can think without symbols (not
coded),
since thinking is a conscious experience, hence first person
singular (not coded).
Since it is personal, it can to some extent be communicated,
but there is always a loss converting experience to symbols,
expressing in words my expeience, what I thought and concluded,
which need not be in symbols.
The conscious experience of a machine is not related only to the
symbolic manipulation that the machine does, but in the relation
between the truth about the machine, and that manipulations, and this,
even for machine, can be shown, in computer science and mathematical
logic, not amenable to "only" symbols.
So your argument does not go through, and btw, would apply also to a
third person description of a brain or bod, like other told you already.
You are right that consciousness is not purely symbolic, but wrong in
thinking this makes machines non conscious, as machine are confronted
with non symbolic things too, like truth (arithmetical or not).
