# The Forecaster's Dilemma

The corpus is a chorus of named forecasters whose disagreements are as instructive as their agreements — and it teaches, by counter-example, how forecasts fail.

**The capability optimists:** [[entity-dario-amodei]] and [[entity-sam-altman]] (A072) forecast near-term super-intelligence — the very inputs that thicken the [[concept-ai-fog]] and justify [[quote-skyscrapers-vs-tents|tents over skyscrapers]]. [[entity-amy-webb]] (A073) forecasts convergence far beyond LLMs ([[claim-bioengineering-gpt]]).

**The infrastructure realists:** the *same* Altman (A074) concedes it is [[quote-altman-infrastructure|"brutally difficult"]] to build enough infrastructure, while [[entity-jensen-huang]] insists demand is "structural" — bracketing the [[claim-speculative-valuations|bubble]] debate ([[cross-bubble-cycle]]).

**The cautionary tale:** [[entity-geoffrey-hinton]]'s 2016 radiology prediction ([[claim-hinton-radiology-error]], A084) is the corpus's parable of *how a brilliant technologist gets economics wrong* — ignoring [[concept-induced-demand]] and [[concept-complementarity]]. Every other forecast in the corpus should be stress-tested against it.

**The scholar's hedge:** [[entity-toby-e-stuart]] (author of both A072 and A099) offers the most disciplined stance — [[concept-agi-automation-threshold|an economic AGI threshold]] and [[claim-compute-scaling-rate|4×-Moore's-Law scaling]], but with directions strong and *numbers illustrative*.

The meta-lesson: separate **direction** (well-supported) from **magnitude and timing** (speculative). This is the operating manual for [[cross-epistemic-fog]].
