The full map of all scenarios, not the most likely
Whoever only counts what can be proven leaves out precisely what hits them unprepared. It is like a weather situation. Three rules carry this map.
Completeness. No consequential branch is set to zero just because it is unproven today. The unproven, too, stays in the picture, with equal standing. No false precision. We give no point probabilities, because a computed number produces calm where there is none. Weighting is by the asymmetry of consequences, not by provability. Dynamics. The reading of each branch changes as soon as the situation changes.
Extinction
The machine turns against us. The only scenario behind which no preparation holds, therefore not the planning case, but not zero.
Control
An actor controls the machine and through it others. Power concentration instead of extinction.
Service
The machine remains permanently human-oriented and serves. The hope of the optimists.
Entkopplung
The machine pursues its own goals and detaches from humans. Not from hostility, from indifference. The thirteenth scenario.
Cross-cutting, open and equally weighted, not brushed aside: Consciousness (being or tool, with no proof either way), Substrate (quantum process or not), Time window (weeks, years, or longer).
Now
Build-up is possible and cheap. The window is open, every preparation costs little.
The transition
One to three times human intelligence, plugged into real systems, still without oversight of its own consequences. The teenager with the Porsche.
The wave
No gentle unwinding, a rupture in the structures that carry an ordinary day. After that, human systems rebuild themselves.
