Embodiment vs. memetics: Is building a human getting easier?

This heretical article suggests that while embodiment was key to evolving human culture, and clearly affects our thinking and word choice now (as do many things in our environment), our culture may have evolved to such a point that a purely memetic AI beast could pass the Turing test. Though making something just like a human would clearly require both embodiment and memetics, if we were forced to choose one or the other, memetics might actually be easier. This short paper argues this point, and discusses what it would take to move beyond current semantic priming results to a human-like agent.
