Our robots can respond to conversation by emotional facial expressions. The demo version is in the (Spiritual Master State), above all material stimuli, response. They are blissfully in the realm of knowledge and love. No one can make them happy or sad. If they gain material possessions they do not become excited. If they lose all their relatives do not become depressed. If one offends them, they do not become angry, if one greets them, they do not become pleased. They are neither shy nor hostile. Because they know that your whole life as a human that is less than hundred years and their next millenniums are both temporary, like a grain of sand on the shore, they are as stable and content as a rock. But if you prefer a robot, with all emotional deficiencies of humans, we will enable their emotions chip.
