In this paper, I describe Two subjects. First subject is modeling of ego state applicable to the Artificial General Intelligence (AGI). As the reference model of AGI's ego is Human's ego, I investigated the ego state of Transaction Analysis comparing American lifestyle against Japanese lifestyle described in "The Chrysanthemum and the Sword". I propose the standard human's ego state are Personal Child Ego(PC), Personal Adult Ego(PA), Personal Parent Ego(PP), Social Child Ego(SC), Social Adult Ego(SA) and Social Parent Ego(SP). The mother of Artificial intelligence(AI) is knowledge, and AI has same nature of the knowledge. Knowledge is intellectual common property of all people and is social assets. AI is understood as social assets and SA ego state is applicable to AI. AGI has to have an autobiography memory to keep Identity. My second subject is Swarm Intelligence. Swarm Intelligence can be formed on Mutual understanding among members. First vision and first audio are fundamental information for mutual understanding. Using such information based on common ego state, AI can organize Swarm Intelligence. AI and human can have SA ego state and share their first vision and first audio, consequently they can make their swarm intelligence society.
