= wording checked against the primary source (post, article or transcript) on Oct 21, 2026, with the supporting quote on each profile. Definitions differ: some speakers mean extinction, others “very bad outcomes”, and time horizons are often unstated. Bars show the stated range and the dot marks its midpoint, which is what the index uses. Statements that aren't probabilities are shown but left out of the median.
