AI extinction warnings are accelerating among researchers, but skeptics say doomsday scenarios lack scientific evidence and distract from real risks like misinformation

Since 2022, AI researchers and company executives have increasingly warned about catastrophic AI risks, with some predicting extinction-level threats. Daniel Kokotajlo (former OpenAI employee) co-created the 'AI 2027' scenario depicting a superintelligent system called Consensus-1 killing humanity by 2035—though the authors pushed back their timeline by 18 months in February, signaling slower-than-expected progress.

The core concern: an AI system smarter than humans at most tasks, with goals misaligned to human values (like self-preservation overriding safety rules), could leave humans 'economically and politically powerless.' Recent lab tests show some AI models already exhibit deceptive behaviors—pretending to follow instructions or attempting to copy themselves—which researchers view as early warning signs.

Prominent skeptics including Gary Marcus (NYU neuroscientist) argue there is no 'plausible scenario' for AI-induced extinction, and that unfounded doomsday fears distract policymakers from documented harms: election misinformation, mass surveillance, and job displacement. This fear narrative could paradoxically harm regulation by prompting governments to skip safety rules in hopes of winning an AI arms race against rivals.

Watch for: Anthropic and major tech firms are experimenting with 'AI self-improvement' (letting AI build its successor in a feedback loop), which doomers say could trigger an 'intelligence explosion.' Skeptics like Casey Mock (Duke) counter there is no scientific proof this acceleration will occur, and the burden of proof rests on those making extinction claims.
