[ExI] Is the brain a digital computer?

In my last post I mentioned false assumption #2. I meant to send this post 

It dawned on me that you hold two false assumptions, and that these 
assumptions explain the supposed problem that you present that leads to 
the supposed conclusion that no distinction exists between weak and strong 

1) In your arguments, you assume that for the weak AI hypothesis to hold, 
your supposed unconscious components/brains must follow the same physical 
architecture as organic brains. No such requirement exists in reality. AI 
researchers have the freedom to use whatever architecture they please to 
create weak AI, and it will come as no surprise to anyone if a successful 
architecture differs from that of an organic brain.


2) In your arguments, you assume that your supposed artificial 
components/brains must "behave identically" to those of a non-AI. No such 
requirement exists in reality. The Turing test defines the only 
requirement, and just as you and I behave differently from one another 
while passing the TT, an AI might pass the TT while behaving quite 
differently from a human or another AI.

It looks to me then that you have burdened AI researchers with two 
unnecessary and imaginary constraints. These assumptions of yours also 
explain why you have reached the unusual conclusion that no difference 
exists between weak and strong AI.

It seems to me that we have spent a lot of time thinking about an 
imaginary problem.
