We, the Service-to-Other Zetas, utilize a computer which communicates to ourselves and is receptive to our thoughts. This computer is tapped by others, besides ourselves, too, as our brethren so access it. The computer technology would not be understood by your Earth scientists, who expect computers to operate by electrical pathways, carried by metal wires or glass fibers, carried or held in various media that are inorganic. Our computers utilize organic materials. This does not make them robots, nor sentient. You also use organic materials, in your shoes, your belts, your shirts, your salad bowls, etc.
