Thank you everybody for your responses.
Bruno Marchal I looked at your statement, they are very
interesting but some very good neruoscientists argue that brain
is not like computer
Here for example (4min video) Edelman:

The question can be turned around. Why would anyone think a brain is
strongly comparable or identical to a computer? It has some
superficial similarities such as being able to store memory and
logical functions (which are simulated by a computer), but its cells
are not two state systems like computer transistors. AG
A bacteria is already a computer (at least), and a neurone is already
a rather sophisticated society of bacteria and viruses, plausibly
enough. So, a society of billions of neurons should not be compared to
transistors. The substitution level is plausibly much lower than the
level of neurons.
It has been estimated that simulating a single neuron requires a
micro-controller like an AVR, which contains 80,000 transistors.

But we don’t know in Nature anything which at some level is not
emulable by a computer, except for controversial notion like
A) primary matter (if that exists, it is not emulable by a computer)
B) the reduction of the wave packet (if that exists, it is provably
not emulable by a computer).
But there are no evidence neither for A) nor for B).
Bruno
Please give me your thought on that.
