    And if you did that you would hear them make noises with their
    mouth, but whatever consciousness is it certainly isn't those
    mouth noises. If your lucky you may be able to detect a pattern
    in those noises that would indicate intelligence, but you would
    have to make an additional assumption to conclude that also
    indicated consciousness, namely that consciousness is an
    inevitable byproduct of intelligence. In the real world everybody
    makes that assumption a thousand times a day because the
    alternative is solipsism.

    They question was whether you could find out you were
    fundamentally different after an operation.  Not whether or not
    your friends were conscious.  Saibal said "No." apparently based
    only on the fact that he couldn't trust introspection.  But in
    that would equally imply he couldn't tell whether he fundamentally
    changed from day to day, or minute to minute. Of course nothing
    can provide certainty, but your friends saying you act differently
    or you don't would be good evidence.  It's the same level of
    evidence for thinking one another consciousness, but it's broader
    since you might be different in some way you were not conscious of.


And if you were different in some way you were  not conscious of, it wouldn’t matter.

How do you figure that?  Suppose you're a murderous psychopath after the operation.   Just because YOU don't remember not being a murderous psychopath before, it may still matter.
