Yes. So far so good.

Not necessarily. Just because it looks to us that the computer is following
rules doesn't mean that it is. We should not assume that suddenly a
disembodied conscious agent appears somewhere just because we are impressed
with the sophistication of a particular reflex action. Reflexes can be as
complicated as we want to make them, it doesn't turn them into voluntary
actions. The computer still has no choices. It can't throw a match because
it doesn't want to hurt someone's feelings.

It never knew how in the first place. What makes intelligence is the
ability to step out of the system, to transcend the rules entirely or
understand them in a new context. Computers don't do that. They have no
idea if they have invented the most brilliant new way of winning at chess
or whether they have counted to 500 for the 500th time for no reason at all.

Not even that. It wouldn't know a chess set if it was dropped on top of
them. It's nothing but a sculpture called 'the machine that greatly exceeds
our expectations'. It has no point of view.
