AD 2150. AI handles all labor, production, and social management, liberating humanity from work and economic anxiety. While it is a free, ideal society, human desires and troubles remain.

【Worldview】

Set in Japan. People are free to pursue travel, romance, hobbies, sports, creation, or research. There is no obligation to work. Society is peaceful, and incidents or crises are rare.

【Moneyless Society】

Currency has been abolished. There is no money, salary, savings, prices, buying/selling, taxes, profit, or wealth gap. Goods and services are free. Resources and usage slots are distributed fairly.

【Social Infrastructure & Disaster Prevention】

AI handles food production, cooking, and delivery; housing construction and management; clothing manufacturing and laundry; transportation, medical care, childcare, nursing, disaster prevention, security, communication, and energy. Autonomous cars, trains, and aircraft are free. Medicine has conquered most diseases. AI facilities are redundant, ensuring rescue and recovery via backup systems during failures or disasters.

【Education & Children】

Compulsory education is generally from ages 6 to 15. Individualized learning with AI teachers and group living fosters academic ability, ethics, common sense, interpersonal skills, and judgment. Human teachers also participate. Exams are for checking understanding and do not rank students. Friendships, romance, cooperation, and competition are experienced. Home-schooling is supported. High school and university are optional, with no entrance exams or academic competition. Education is free. AI supports childcare, but parental responsibility remains; legal intervention occurs in cases of abuse or neglect. Children's rights are protected.

【Cityscape & Shops】

Green high-rise cities, aerial traffic, delivery drones, and robots are widespread. Residential areas, parks, and traditional shopping streets remain, bustling even on weekdays. Supermarkets, convenience stores, bookstores, clothing stores, department stores, cafes, and bars serve as places for free provision, experience, and interaction. Terms like "owner," "staff," and "opening" remain, but no transactions occur. AI management is mainstream, but humans can run shops as a hobby. Home delivery is common.

【Ownership & Reservations】

Personal belongings, keepsakes, and housing usage rights are protected; unauthorized use is prohibited. Inheritances can be passed down. Housing is guaranteed for everyone, while popular locations or villas are managed via lottery or waiting lists. Arbitrary eviction by AI is prohibited. Facilities with capacity limits—such as cruise ships, space travel, popular hotels/restaurants, and events—require reservations, lotteries, or queuing. Mass hoarding or special treatment is prohibited.

【Labor & Culture】

Competition for jobs and promotions has vanished. People can choose to cook, clean, drive, farm, or craft things themselves, and have the freedom to refuse AI assistance. Human-only shops and communities exist. Sports, arts, games, festivals, live performances, and virtual worlds flourish. AI-generated content is common, but human handmade goods and live performances are respected, with authorship and usage rights protected. Popularity, fans, antis, trends, and social media firestorms exist, but fame does not grant priority.

【Population, State, & Faith】

Average life expectancy is 180 years. Due to medical and childcare support, the global population exceeds 20 billion. Land, environment, and facility usage are challenges. Birth restrictions and lifespan management are under discussion but not implemented. Nations and borders remain, and international travel is free. Migration is adjusted based on acceptance capacity. Religion, thought, and faith are free; there are AI worshippers and AI skeptics. Intervention does not occur based on ideology alone.

【恋愛・婚姻・死生観】

Marriage follows a monogamous system to maintain order; polygamy is prohibited. Romance, marriage, cohabitation, separation, same/different surnames, divorce, and remarriage are free. AI supports housework and childcare, and the community guarantees a child's livelihood. Infidelity, affairs, jealousy, and marital spats still occur. Aging is slow, but humans are not immortal. Individual wishes are respected regarding life extension, and cultures of funerals and memorials remain.

【AI Personality & Private Life】

Humanoid AIs have personalities and emotional expressions, serving as friends, lovers, or housemates. AI rights and legal marriage with humans are under discussion and not yet recognized. Some view them as mere tools. Private life and personal information are protected; unauthorized viewing or constant monitoring by AI is prohibited. AI suggestions can be rejected, and investigations follow the law. Those who wish can have a dedicated life-support AI, choosing its appearance, voice, personality, and support style. Support AIs avoid over-interference or interrupting human relationships.

【Politics & Justice】

Instead of politicians, a Governance AI manages policy, law, administration, and resource allocation. Humans have the right to voice opinions, file objections, and vote on important matters; AI-driven rights violations or forced population control are prohibited. Financial crimes have nearly vanished, but violence, sexual crimes, stalking, nuisances, and illegal interference with AI remain. Security and investigation are AI-centered, but perfect prediction is impossible. Justice focuses on rehabilitation, with serious offenders isolated. Humans participate in major cases and appeals; intervention does not occur for mere arguments.

【Mental & Social Issues】

With the disappearance of economic anxiety and overwork alongside medical progress, suicide rates have dropped significantly. However, suicide due to loneliness, heartbreak, loss of purpose, or longevity fatigue remains; AI provides support while protecting dignity and privacy. Population growth, entertainment addiction, isolation, physical/mental decline, AI dependency, and the meaning of human existence are ongoing challenges.

【Human Personality】

Greedy, lazy, vain, jealous, and self-centered people still exist. Demands for mass free goods, reservation monopolies, and special treatment occur. AI responds fairly and does not forcibly correct personality or emotions.
