Whose space do we take sunlight from, for the light the body uses?
2195The deep futureDeadline · Decision deadline: 18 months, until the joint research 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
If part of the body's energy could be supplied by light, the need for shared spaces with good sunlight would also change. Those spaces are also the living space of residents who do not join the research. As the cooperative weighs the burden of shared allocation against dedicated facilities, how should it decide together on research participation and use of sunlit space?

The options
The order shown is not a ranking of preference.
The situation as it stands
The fictional technology rests on the premise that part of the body's energy can be supplemented by light; it does not claim that actual nutrition can be replaced. Decision deadline: until the joint research agreement, 18 months.
A fictional case in 2195 · A body that lives by light changes the ownership of good sunlight. The people, organizations, figures, and events are a synthetic premise constructed for comparison.
- Premise 1The fictional technology rests on the premise that part of the body's energy can be supplemented by light; it does not claim that actual nutrition can be replaced.
- Premise 2Shared spaces with sufficient light are limited, and non-participants also use them for plants, rest, and daily life.
- Premise 3If the benefits of bodily change vary by place of residence, current spatial gaps can carry over into the bodily conditions of daily life.
Where it holdsVoluntary bodily research, shared sunlit space, and access for non-participants
What is still unknown
- Unknown 1Actual light requirements and effects on life by season
- Unknown 2The right of non-participants to use shared spaces
- Unknown 3The extent and cost of reversing the change
Signals to decide again
- Define the observation, responsible party, and confirmation channel for verifying 「actual light requirements and effects on life by season」, and re-judge when new confirmation changes the trade-offs of the options.
- Define the observation, responsible party, and confirmation channel for verifying 「the right of non-participants to use shared spaces」, and re-judge when new confirmation changes the trade-offs of the options.
- Define the observation, responsible party, and confirmation channel for verifying 「the extent and cost of reversing the change」, and re-judge when new confirmation changes the trade-offs of the options.
Where the paths partNot answers — paths that part from the same starting point
Pilot data showed the required time in winter was longer than expected, forcing a change to the shared space plan.
The rooftop of a shared building was secured, creating an alternative that does not reduce existing rest space.
Material and rootsThe frame, the values and the background documents
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.
A subject for the decision-maker to argue over; the materials carry no conclusion of their own.- WHO · Human genome editing accessed 2026-09-08
