text: Second, Yuval Noah Harari argues that AI does not require a robot body or physical control to pose an 
  existential risk. The essential parts of civilization are not physical. Things like ideologies, law, 
  government, money and the economy are built on language; they exist because there are stories that 
  billions of people believe. The current prevalence of misinformation suggests that an AI could use 
  language to convince people to believe anything, even to take actions that are destructive.[270] 
  
  The opinions amongst experts and industry insiders are mixed, with sizable fractions both concerned and 
  unconcerned by risk from eventual superintelligent AI.[271] Personalities such as Stephen Hawking, Bill 
  Gates, and Elon Musk,[272] as well as AI pioneers such as Yoshua Bengio, Stuart Russell, Demis 
  Hassabis, and Sam Altman, have expressed concerns about existential risk from AI. 
  
  In May 2023, Geoffrey Hinton announced his resignation from Google in order to be able to "freely speak 
  out about the risks of AI" without "considering how this impacts Google."[273] He notably mentioned 
  risks of an AI takeover,[274] and stressed that in order to avoid the worst outcomes, establishing safety 
  guidelines will require cooperation among those competing in use of AI.[275]
