Well, I don't expect to need to write code that does that explicitly. A sufficiently powerful machine learning algorithm with sufficient computational resources should be able to:

1) Learn basic perceptions like vision and hearing. 2) Learn higher level feature extraction to identify objects and create concepts of the world. 3) Learn increasingly higher level concepts and how to reason with them. 4) Learn to reason about morals and philosophies.

Brains already do this, so its reasonable to assume it can be done. And yes, I am advocating a Bottom Up approach to A.I. rather than the Top Down approach Mr. Yudkowsky seems to prefer.
