At a guess there are two major schools of thought here. The first thinks that emotions, will, personality etc are much more complex than the way we think of neural nets today. The other thinks that what we are seeing is already much more like the brain than we were expecting and if we continue down this path we may discover those things are emergent aspects of much simpler behaviours at a small scale.

My slightly optimistic money is on the latter one.
