I found these really interesting. I recall some 45 years ago I read a book 
called "Mechanical Man" by Dean Wooldridge (physicist, worked for Bell Labs, 
Hughes Aircraft, and his own company which became TRW). This book attempted to 
explain the workings of the human brain in strictly physical terms. 

 I have often felt that regarding human beings as simply computational machines 
with running programs and grasping appendages and transducers (speech and 
hearing) often simplifies interaction with others of my species (and other 
species as well), and provides an apposite explanation for the rather odd 
behaviour, that from the perspective of this machine, infects my fellow mammals.

 This mechanistic view is necessary if we regard AI and AGI as a real

 One of my favourite inspirational thinkers holds forth on the problems facing 
Artificial Intelligence research:

 To state that the human brain has capabilities that are, in some respects, far 
superior to those of all other known objects in the cosmos would be 
uncontroversial. The brain is the only kind of object capable of understanding 
that the cosmos is even there, or why there are infinitely many prime numbers, 
or that apples fall because of the curvature of space-time, or that obeying its 
own inborn instincts can be morally wrong, or that it itself exists. Nor are 
its unique abilities confined to such cerebral matters. The cold, physical fact 
is that it is the only kind of object that can propel itself into space and 
back without harm, or predict and prevent a meteor strike on itself, or cool 
objects to a billionth of a degree above absolute zero, or detect others of its 
kind across galactic distances.
 But no brain on Earth is yet close to knowing what brains do in order to 
achieve any of that functionality. The enterprise of achieving it artificially 
– the field of "artificial general intelligence" or AGI – has made no progress 
whatever during the entire six decades of its existence.
 Despite this long record of failure, AGI must be possible. That is because of 
a deep property of the laws of physics, namely the universality of computation. 
It entails that everything that the laws of physics require physical objects to 
do can, in principle, be emulated in arbitrarily fine detail by some program on 
a general-purpose computer, provided it is given enough time and memory.
