If lives grow longer, when does child-rearing end?
2120The deep futureDeadline · Decision deadline: 1 year, until the long-term reproduction and child-rearing agreement
Civilisational assumption
The people, events, figures, and technology in this matter are stated assumptions. They are not to be treated as information about real individuals or as observed events. Background documents are separate sources, and symbolic interpretations are recorded as discovery paths.
The question to decide
Even if lifespan can be greatly extended, if maturation needs nearly twice the time, a community whose parents' lifespans stay the same is left with longer child-rearing duties. Start longevity research for the generation born carrying that duty, or first find a path that applies to adults, or postpone reproductive use?

The order shown is not a ranking of preference.
The situation as it stands
This world presents the possibility of greatly extending lifespan, but it is assumed that growth and maturation also take nearly twice as long. Decision deadline: 1 year until the long-term reproduction and child-rearing commitment.
Fictional 2120 scenario · A long-lived body requires late maturation. The people, organizations, figures, and events are a synthetic premise constructed for comparison.
- Premise 1This world presents the possibility of greatly extending lifespan, but it is assumed that growth and maturation also take nearly twice as long.
- Premise 2The current child-rearing and education systems are fitted to the existing life cycle, and the lifespan of research-participating parents is unchanged.
- Premise 3The actual daily-life benefits of longevity and the preferences of the new generation cannot yet be observed.
Where it holdsVoluntary commitments on research, child-rearing, and intergenerational support among participating households
What is still unknown
- Unknown 1The relationship between delayed maturation and actual life function
- Unknown 2The party who will take over child-rearing responsibility after the parents
- Unknown 3The choice to leave the research after the person has grown up
Signals to decide again
- Decide what observation, responsible party, and confirmation channel can verify 「the relationship between delayed maturation and actual life function」, and reconsider the judgment when new verification changes the tradeoffs of the options.

Where the paths partNot answers — paths that part from the same starting point
In a fictional long-term follow-up, physical maturation and the development of judgment ability appeared to progress at different rates.
The community's next generation accepted inheriting the child-rearing fund but expressed opposition to expanding the trait.

Do people accept both the benefits of a new capability and the life that capability demands?
An exploratory perspective chosen by the creator. Does not claim supernatural validity or the superiority of any particular option.The benefits and costs of the options accrue to different stakeholders. Which loss to accept remains undecided.
