Three categories of AI risk, and why extinction is not yet evidenced

Professor Nick Jennings outlines three dramatic classes of AI risk — loss of human control, emergent superintelligence and concentration of power — and argues that moving from possibility to probability requires a long chain of assumptions that has not yet occurred. He calls for built-in safety, oversight and clearer justification from developers continuing frontier work.
