Geoffrey Hinton, who is famously known as the “Godfather of AI,” has left his role at Google to express his concerns about the potential dangers of AI. He has contributed to Google’s AI development efforts for a decade on a part-time basis, but he has now expressed concerns about the technology’s rapid advancement and the possibility of eliminating jobs and creating a world where people “will not be able to know what is true anymore.” Hinton’s decision to leave Google and speak out comes amid growing concerns from lawmakers, advocacy groups, and tech insiders about the potential for AI-powered chatbots to spread misinformation and displace jobs.

Hinton has left Google to speak freely about the risks of AI, regardless of how it may impact Google. He acknowledged that Google had acted responsibly, and Jeff Dean, Google’s chief scientist, expressed appreciation for Hinton’s contributions to the company and its commitment to a responsible approach to AI. Hinton is not the first Google employee to raise concerns about AI. In July, the company fired an engineer who claimed an unreleased AI system had become sentient, saying he violated employment and data security policies. Many in the AI community pushed back strongly on the engineer’s assertion. In March, a letter signed by prominent tech figures called for a halt to the training of the most powerful AI systems for at least six months, citing “profound risks to society and humanity.” Hinton’s decision to leave Google and speak out adds to the growing concerns about AI and its potential risks.
