The Uncanny Valley

Peter posted a link the Uncanny Valley in the comments to the story about the Female Android. This is an interesting concept to me. I wonder if anything will ever be able to come out to the other side of the valley. Will androids always need to be a little inhuman for us to like them or could we accept them being just like us? It might take a few generations of living with androids before we can accept them looking like us.
