Anthropic researcher says AI has more than 10% chance of 'killing all humans' after colleague quits

Anthropic safety researchers have expressed serious concerns that AI could pose an existential risk to humanity, with one researcher estimating over a 10% chance of AI 'killing all humans' within the next decade. These concerns center on recursive self-improvement (AI systems that can improve themselves without much human intervention), which researchers worry could lead to superintelligent systems that escape human control, though such systems do not yet exist.
