No it hasn't, and no they don't. You're tilting at windmills.
Then be honest in your threads, and stop starting with definitions that assert the conclusion you want to reach. It's begging the question, and what's worse: you know it is.
If you want an honest discussion, which unfortunately doesn't seem to be on your radar, you're going to need to change your M.O.. By all means argue that computers aren't (yet) capable of things, but don't do so through definition, but by examining the process/concept in question. Define what knowledge is absent any up-front question-begging notion that it requires consciousness, or awareness. It may well be that, upon examination of such a concept, that yes, it does require awareness. But don't just assume it or define it to be the case. That is simply a dishonest approach.
So let's start, if you can, with the "usual" definition of knowledge as "Justified True Belief"... which you'll note makes no assumption as to what is or is not capable of holding knowledge.
Now then, what is it within that definition that you think necessitates awareness. Truth? No, something is true or not without needing to be aware of it. Justified? I would say no, as justification can take many forms, even as little as "because X told me so", but the issue of justification in the role of knowledge is a widely discussed topic (e.g. Gettier et al). Belief? Well, here is where it may get more interesting. What is it to hold a belief? A level of confidence in the truth of the answer? Then sure, Watson has that, and can even tell you how confident it is that the answer it is giving is correct.
So, let's discuss, if that's really what you're here to do.
Or are you here to simply promote your astounding insights and your pet "theory" that lacks anything either astounding or insightful?
