AI safety researchers and cybersecurity experts have renewed calls for stronger safeguards after former Anthropic researcher Jacob Coxon warned that advanced artificial intelligence could pose an existential threat to humanity by the end of the decade.
Coxon announced his resignation from Anthropic on 8 September 2026 and subsequently warned on X that advanced AI could pose an existential threat to humanity. His warning spread rapidly online because it went beyond the usual discussion of faulty chatbots, job losses or deepfakes.
