We could think of ourselves as walking organic computers. Neurons
have an 'all or nothing' on/off state and will only fire
(switch on) if the stimulus reaches a specific level of intensity.
In that sense, we are a walking collection of on/off switches.
However, this does not necessarily explain HOW the mechanism works.
Yes, at a neural level, all information is processed as a series of
1's and 0's - neurons firing and not firing. It is how this is
organised and how this action translates from 1's and 0's to speech,
memory, language, conscious awareness etc. which is the unknown.
For example, imagine we found an item of alien machinery (as you do!).
Scientists and engineers could spend years studying this machine, detail the
components in minute detail, but still be none the wiser for HOW it
works, or what it is for.

Symbolism offers one possible explaination for how we process
information. It isn't necessarily HOW we process sensory
information, but as you say, AI research has shown it can work in
limited areas. It is important to remember that in this field there
is no one answer to how the mind/brain works, but many feasible yet
