What shifts you between these timelines

Every lever below is something an actor can push on. Changing one of these moves pull strength between the two timelines in a way downstream readings should pick up.

• AI alignment research pace

  How fast the field proves that frontier systems do what we meant, not what we literally said.

• Nuclear restraint and arms control

  Whether the current drift of eroding treaties reverses in time, or compounds into a doctrine shift.

• Biosecurity preparedness

  Pandemic-response infrastructure, DNA synthesis screening, and dual-use biology containment.

• Climate response speed

  Deployment pace of grid-scale clean energy and whether tipping-point feedbacks fire first.
