Paper: The Great Filter hypothesis -- a new Great Filter?

What they're saying

Predicts human extinction "some time after year 2500" based on declining TFR using exponential decay models...

The Critique

Assumes TFR trends from 1963-2023 continue unchanged for 500+ years. Ignores AI/automation changing economic incentives, pro-natalist policies, demographic transition theory, and selection effects where higher-fertility subpopulations become more prevalent.

Why It Matters

Making extinction predictions based on naive exponential extrapolation without accounting for adaptation is alarmist pseudoscience dressed in mathematical formalism.

What They Missed

Assumes TFR trends from 1963-2023 continue unchanged for 500+ years. Ignores AI/automation changing economic incentives, pro-natalist policies, demographic transition theory, and selection effects where higher-fertility subpopulations become more prevalent.
