Unaligned AI

Unaligned artificial intelligence represents the single most probable cause of human extinction amid accelerating technological trends. Rapid progress toward artificial general intelligence, as evidenced by 2026 expert surveys estimating a median 10-20% probability of existential catastrophe this century, outstrips other risks. Superintelligent systems could pursue misaligned goals, leading to loss of control, resource competition, or autonomous actions incompatible with human survival. This dwarfs slower threats like climate change (estimated at 1-in-1000 extinction odds) or nuclear war, though geopolitical tensions may compound AI dangers through rushed deployment and weaponization. Environmental and societal pressures add instability but lack comparable near-term extinction potential. Without resolved alignment, current development trajectories make this outcome the leading existential pathway.
