Vitalik Buterin has critiqued the apocalyptic predictions of the "AI 2027" report, which suggests that super AI will rapidly emerge and easily destroy humanity. In his blog post, Buterin argues that such assumptions are exaggerated. He believes the timeline for AI development may extend beyond 2027 and emphasizes that humans possess potential technological and defensive capabilities in areas like bio-defense, cybersecurity, and information interference. Buterin stresses the importance of not underestimating the feasibility of symmetric defense strategies against AI threats.
