Q. How is Sim Eternal City different from a typical retirement home?

A. While traditional retirement homes are "final destinations" for medical care and consumption, Sim Eternal City is an "Active City" where seniors continue to produce wisdom and engage in economic activities. We define the elderly not as subjects of support, but as core assets who pass down civilization and knowledge to the next generation.

Q. What is the "18-Minute City"?

A. It is a concept that combines the "15-minute physical living zone" with "3 minutes" of spiritual connection.

• 15 Minutes: All daily needs—including medical care, dining, and community activities—are met within 15 minutes inside a compact city formed by four connected cruise ships.

• 3 Minutes: This is the "Value Production Time" where citizens connect to the Life Tree for 3 minutes a day to record memories or share wisdom with the mainland.

Q. How is the city constructed?

It features a "Diamond Grid" structure, connecting four decommissioned mega-cruise ships in a diamond formation. Each ship specializes in medical care, housing, production (vertical farming), or culture. At the center lies the Central Plaza, a massive floating square where seniors and humanoids interact.

Q. Why recycle decommissioned cruise ships?

A. It is the fastest and most eco-friendly housing solution in the era of climate crisis. Instead of building new artificial islands, we upcycle cruise ships that already possess power generation, water purification, and residential cabins, minimizing resource waste and allowing for immediate occupancy.

Q. Is the "Life Tree" just a decorative sculpture?

A. It is the fastest and most eco-friendly housing solution in the era of climate crisis. Instead of building new artificial islands, we upcycle cruise ships that already possess power generation, water purification, and residential cabins, minimizing resource waste and allowing for immediate occupancy.

Q. Who are the citizens of this city?

A. Two types of citizens coexist in perfect harmony:

• Citizen 1 (The Elders): Seniors who lost their homes to the climate crisis but possess a lifetime of wisdom. They are the city's decision-makers and knowledge producers.

• Citizen 2 (Humanoids): AI robots that compensate for the physical limitations of the elderly. They handle labor, nursing, and logistics, serving as dedicated partners to the seniors.

Q. What is the city's revenue model?

A. It is a "Knowledge Circular Economy." The Life Tree processes the experiences (skills, history, know-how) of the seniors into "Masterclasses" or "Digital Archives," which are then sold or licensed as educational content to schools, corporations, and governments on the mainland (Land City).

Q. How is the Basic Income distributed?

A. Revenue generated from content subscriptions on the mainland is distributed back to citizens as a "Knowledge Dividend" (after city operating costs), ensuring a stable and secure retirement.

Q. Is the city safe during climate disasters?

A. Yes. The Diamond Grid structure responds flexibly to waves, and the city naturally floats as sea levels rise. In the event of mainland flooding or disaster, Sim Eternal City serves as an "Ark of Knowledge," preserving human civilization and data.

Q. Is the city isolated from the mainland (Land City)?

A. No. It is a mutually beneficial, symbiotic relationship.

• Land → Sea: Supplies food, materials, and young professional manpower (such as medical staff).

• Sea → Land: Provides the "Wisdom of Elders" (educational content), climate adaptation solutions, bio-data, and advanced Death Care services.
