One quote from the very long comparison:
What makes the Golem work? In both cases it is energy. In the old Golem it was the energy of speech, in the new one it is electronic energy. In the case of the Kabbalists it was the Shem ha-Mephorash, the fully-interpreted and expressed and differentiated name of God. Now, it is still differentiation according to a given system and interpretation of signs and ciphers which makes the Golem work.
