You've shifted the goalposts and erected strawmen so many times in this brief passage, I hardly know where to start...
> No matter how many Turing Test they pass, intelligent machines will be no more conscious or self-aware than the Mechanical Turk!
I see. Well, this is just a rephrasing of the "Chinese Room" discussed in the article. Taken to it's logical conclusion, I am certainly self aware, but the rest of you are all just acting out complex behaviors encoded in chemical and electrical gradients, successfully mimicking consciousness.
I think that if any entity exhibits the behaviors associated with conscious thought, it would well behoove us to treat such entities as conscious, or we may very well find ourselves holding the short end of that particular stick sooner than we'd like.
> That's because solving the problem of self-awareness, or consciousness is a different engineering challenge than solving problems of AI. Consciousness is a more complicated, and specialized a thing.
Since there is no doubt that ML/AI has a long way to go toward AGI, and along the way we can expect the discipline to evolve considerably in many unexpected directions, this assertion of yours is close to tautological.
> Were we to build an artificial self-awarene machine we would not expect it to pass a Turing Test.
Why not?
> Instead we might expect different things of it and ask different questions to determine if it is self aware: can it adapt and survive without human help,
So, anyone severely ill to the point that they cannot do without assistance is not conscious and self aware?
> ie can it trap and store energy and reproduce itself,
So, a single-celled organism is conscious?
> and what purpose does it find for itself is what objective does it pursue ...
Ah, this seems a relevant criteria, but keep in mind that humans can be subjected to operant conditioning ("brainwashing") to impose external goals, not to mention that humans actually require a couple of decades of such conditioning (albeit rather more gradual and haphazard) before being considered competent members of society, but we don't consider humans to be less conscious or less self-aware on either side of that particular divide.
> it's a different engineering challenge than producing information that is organized to be sensible to human mind, which is the AI challenge, and the Turing Test.
Given that people have to be specially educated to produce information that is organized to be sensible to a computer, I don't see why an AGI, whatever it's capabilities "out of the box", so to speak, shouldn't be expected to be capable of learning to be sensible to humans.
