If we accept the actual facts of evolution, and not the hype pushed by physicalist believers, then the only relevant facts we have are common decent and genetic variations that either produce useless/destructive changes or which produce simple superficial beneficial changes like bigger bird beaks, longer monkey tails, new colors, etc.
There are no "facts" of evolution that show genetic variation (along with natural selection) has produced high-functioning organs or organisms.
You are wrong when you say that there are no "facts" that show that genetic variation along with natural selection produces, over time, complex systems such as high-functioning organs (brain, heart, liver, hands, etc) or orgamisms (such as humans). On the contrary Biological Sciences are replete with facts and examples that demonstrate the validity of Evolution. By saying that it is all "hype" you are reducing the entire field of Biology (along with Geology, Paleontology and Astronomy for good measure) to a few frivilous musings of a mind.
Getting to your point, that "a sufficiently advanced AI with a complex enough mind can be said to have a mind of its own and be self-aware," I don't see it. First of all, we don't know that the basis of subjectivity is complexity. I've pointed out (many times) that if subjectivity arises from complex mental functions, then why do meditators (who still the mind and therefore mental complexity) not only retain subjectivity, but report that it is strengthened when the mind is silenced?
Well this point works only if you accept the fact of Evolution ... which you, it seems, do not. Also I am new to these forums so I don't really know how many times you have mentioned your example of meditators. Sorry.
I don't see how you can logically say that "stilling/silencing your mind" equals "reducing it's mental complexity". It's like saying that by idling your car you make your engine smaller and less complex. The mind/brain is still there even if you don't use it, and it's just as complex as if you would. All the meditators do is learn a trick, to make their brains produce alpha waves at will. This requires a lot more work and concentration to produce than what any average one of our brains could do. Videogamers are known to produce alpha waves because of the intense mental concentration required to keep a game going. Nor do I see how subjectivity cannot be retained when you concentrate.
However, you are wrong to say the only difference between me (human consciousness) and a virus is complexity. The big difference is my subjectivity which a virus cannot be shown to possess.
Could it be that the right kind of complexity eventually produces subjectivity/self-awareness? Subjectivity originates within the brain. The more complex the brain the more likely that it will be self-aware and subjective.
Yes, macroevolution is what's unsupported by evidence. In terms of what I "believe," personally speaking, I believe what is supported by proper evidence. Otherwise, I believe nothing.
What in your opinion constitutes "proper evidence"? Is this a definition that you have outlined for yourself or is this an official definition that everyone (including scientists) agree on? Don't really want to turn this into an evolution debate... but I feel it's beginning to drift that way :)
Personally I think if all transitional forms had been preserved, there really would be a record showing that all life evolved from the first life forms (algae/bacteria). The reason I think there is no fossil record is because the evolution of new life forms happened too fast, so there weren't enough transitional forms to ensure a fossil record.
Well the fossil record is far from perfect. You really cannot expect for everything to be preserved that once lived upon this Earth what with all the Earth processes and erosion etc. Paleontologists and geologists go by what they got. In fact we are lucky to have anything at all! It takes some special processes to preserve life for us to be able to examine it and extract data from it. Another reason would be that a lot prehistoric life was soft-bodied leading to a spottier fossil record.

One more bit of evidence I think that is virtually indisputable is the genetic record which clearly indicates common descent.
So if common descent is true, if all life forms did evolve from more primitive forms, then is there any reason not to extrapolate macroevoluation from microevolution?
YES! The problem is that in Darwinistic evolution theory genetic variation and natural selection are the only mechanisms we have for producing changes (well, plus how disease or changes in environmental chemistry might alter an organism). But today we cannot find evidence that genetic changes produce new organs. Bigger bird beaks, new shades of moths, longer monkey tails . . . no problem. But not organs.
You seem to agree that genetic evidence clearly indicates common descent and that it is indisputable yet you then deny macro evolution on the basis that we cannot see/have not seen new organs evolving. The problem, I think, is your understanding of how evolution works. Evolution does not produce new structures/organs overnight. They evolve over long periods of time. Also new structures are not new at all but modified existing ones (homologous structures). If you look at a bird's wing you would be tempted to say that it's a new organ... but it isn't, it's a modified leg/paw of the organism from which, depending on how far back you want to go, it evolved (some type of dinosaur like archeoapterix which in turn evolved from another creature). And if you go far back enough the thing from which the leg evolved would no longer be anything remotely like a leg but it would still be the same structure from which the leg and then the wing evolved.
Then you have the Cambrian explosion where virtually every phyla of animal first appears within a 10 million year period. There is no known mechanism for producing that quality and quantity of change. Certainly not accidental genetic variation and natural selection; they operate a billion times too slowly (at least as they are observed today) to attribute the kind and quality of changes that took place during the explosion.

I gave you a couple links for your reference. Although there certainly was an explosion/diversification of life during the Cambrian era this is a creationist claim and it is false. The previous links explain why but I will summarize. Basically there were many animal groups/phyla existing before Cambrian. The reason we have a good record of Cambrian fauna is because that was the period when many hard parts in animals (teeth, shells) first developed. As you probably know bone preserves much better than soft tissue which attributes to the scarcity of fossils before Cambrian. More fossils preserved (due to the hard parts) does not mean there were more animals back then, just more and better fossils. This claim does not in any way disprove macro evolution. Animals as we know them today (mammals, reptiles, birds, insects, spiders), which did not appear in the Cambrian, still evolved from the Cambrian animals (which were more like molluscs and trilobytes) via macro evolution. There are several factors that could have led to this explosion, but they only served as a catalyst for macro evolution.
