## The prompt

```
Use only the evidence in this notebook to project three future scenarios over the next 24 months.

For each of Optimistic, Base Case, and Pessimistic, produce:
1. Headline outcome in one sentence.
2. The 3 key drivers (each with the source that supports it) that would push the world toward this scenario.
3. The strongest piece of counter-evidence in the notebook that argues against this scenario.
4. Three leading indicators — concrete, observable signals over the next 6 months that would tell you this scenario is unfolding.
5. The first decision someone reading this should make differently if they believed this scenario.

End with:
- A probability you'd assign each scenario, summing to 100%, with a one-sentence justification grounded in the sources.
- The single signal that, if observed, would most strongly shift weight between scenarios.

Do not invent drivers or indicators the notebook can't support. Speculation is fine; fabrication is not.
```

## How to use it

1. Open your notebook at notebooklm.google.com.
2. Replace the [bracketed] parts with your specifics.
