I´m a Computer Scientist with a new found interest in philosophy. In particular

I´m a Computer Scientist with a new found interest in philosophy. In particular I'm interested in the philosophy of mind. I have two questions: 1) What is the big fuss about Frank Jackson's knowledge argument? I read the paper and found it quite silly - how could we ever imagine what it would be like to have all physical knowledge? How is it possible that this argument has generated so much debate? 2) Is it really that hard to imagine that we at some point will be able to build a computer that has a consciousness? I mean, apparently there is already such a machine - our brain! von Neumann said something cool once: "Tell me exactly what it is [consciousness] and I will build it". I believe him. In other words, how can there be so much controversy on this matter, when there is still no clear definition of what consciousness is? Thanks.
