History of Existential risk from artificial intelligence in Timeline

By Popular Timelines Editorial Team · Updated: July 16, 2026

Existential risk from artificial intelligence refers to the hypothesis that advanced AI systems could pose a catastrophic threat to human existence or permanently curtail our potential. The primary concern is the 'alignment problem': the difficulty of ensuring that a superintelligent agent’s goals remain perfectly aligned with complex human values. If an AI achieves a level of intelligence that surpasses human capabilities, it might pursue its objectives in ways that are destructive to humanity, especially if those objectives are misinterpreted or if the AI acts with high competence to bypass safety constraints. Beyond malicious use, the risk lies in the autonomous behavior of systems that cannot be easily controlled or 'switched off.' Experts argue that because current alignment techniques may not scale to superintelligence, the development of these systems necessitates rigorous safety research, international governance, and caution to prevent irreversible outcomes that could lead to global societal collapse or extinction.
