        No, Scott Alexander did, he's a pretty smart guy but I think
        he got some things wrong. I did write this in the comments
        section:

        "You say "If we’re lucky, consciousness is a basic feature
        of information processing and anything smart enough to
        outcompete us will be at least as conscious as we are" and I
        agree with you about that because there is evidence that it
        is true. I know for a fact that random mutation and natural
        selection managed to produce consciousness at least once
        (me) and probably many billions of times, but Evolution
        can't directly detect consciousness any better than I can,
        except in myself, and it can't select for something it can't
        see, but evolution can detect intelligent behavior. I could
        not function if I really believed that solipsism was true,
        therefore I must take it as an axiom, as a brute fact, that
        consciousness is the way data feels when it is being
        processed intelligently.

        />You've written this before, but I slightly disagree with
        it. I think Evolution can detect consciousness as directly or
        indirectly as intelligence. /


    I agree,Evolution can detect intelligence so it can only detect
    consciousness if it is an inevitable byproduct of intelligent
    data-processing.
    You're missing my point that there are at least two different
    meanings of "conscious" and only one necessarily accompanies
    intelligence (and isn't exactly a "byproduct")  It's just
    awareness or perception.  It doesn't include reflection and
    self-awareness, but in can include a lot of intelligence,
    including learning.

    The second meaning, which is the kind we prize as uniquely human,
    is self-awareness.  I think it's what you refer to as a
    "byproduct", but my point is that it's another level of
    intelligence and hence is subject evolution just like any other
    aspect of intelligence.  This second meaning is planning, and
    planning depends on having a self-model.  If I do this and that
    happens how will I feel and what will I do then.


There is yet another level, phenomenal consciousness, which has no behavioural manifestations whatsoever, allowing for the theoretical possibility of philosophical zombies. Some claim that phenomenal consciousness reduces to one of the other kinds, and therefore that zombies are impossible.
That's the kind that couldn't evolve and so I agree with JC that it's unlikely to exist.
