>From What I remember of the book, Yes his argument hinges on a reductionist
view of an algorithmic machine. VERY simply put he says that any two
computing machines attempting to mimic the human brain will behave in an
identical manner - i.e. no personality, individuality etc.

To my mind he is neglecting the possibility of the system being non-linear
with the attendent possibility the emergence of complexity with its
attendent "sensitivity to initial conditions". This route could give the
required differences for the emergence of personality etc.
