Could you build a robot to mimic all human functions? I think something
like balance would be very difficult to implement in a robot as everybody
has a different balance. Balance also degrades with age, like most (if not
all) human functions. If a robot were able to mimic all the human
functions, would they interact with each other in exactly the same way. I
believe that this would be very difficult to achieve.

I don't think that consciousness can be solely described as a set of rules
and facts that one follows. If it were then it would make trying to
reproduce it almost impossible as there would be far too many rules to
make this plausible.

I don't think that it should be dismissed that because, at the moment,
humans cannot make efficient use of mechanical aids then robots could not
make use of an organic structure. I believe that we are not too far away
from having really god artificial limbs, each year you hear about a new
artificial limb that is a lot better than previous ones. I think that it
would be possible to use an organic structure on a robot.

This is possible, but is it practical. If you wanted to have an infant
robot develop the same way as a human robot than it would take a long time
for the robot to become fully developed. I don't think that science is

I agree that rules that are built in cannot be useful in the learning
process. They are merely refining the rules of the learning process to
make it more practical (i.e. the robot not destroying itself).

How difficult would it be for the robot to learn another language as
well. Would it get confused between the two? I think this is an
interesting pint that could be discussed further.
