Nvidia’s chief executive, Jensen Huang, has dismissed claims that artificial intelligence could become advanced enough to cause human extinction within the next few years, describing such predictions as exaggerated “doomsday narratives”.

Huang, co-founder and CEO of the $5tn AI chipmaker, was responding to comments by former Anthropic researcher Jacob Coxon, who said on social media that AI could become “superhuman” and potentially wipe out humanity within the next decade.

Huang described the claims as “irresponsible”, arguing that AI is unlikely to develop to a level that would pose such an existential threat to humanity in the near term.

“2030 is not going to be the end of the world. There is 0% chance that’s going to be the end of the world,” Huang said in an interview with CBS News. “Scaring people is unnecessary. It is irresponsible.”

Coxon’s comments, which were supported by two other researchers at Anthropic, the company behind the AI chatbot Claude, have fuelled an international debate over the potential dangers of AI and the lack of oversight as technology companies race to develop increasingly powerful models.

US lawmakers have also raised concerns about the risks posed by AI. Anthropic recently published a threat intelligence report detailing attempts by criminals, state-backed groups, spyware companies, scientists and propagandists to use its AI models to design missiles and bombs, develop deadly pathogens and spy on dissidents.

Anthropic CEO Dario Amodei, OpenAI chief executive Sam Altman and Tesla boss Elon Musk have all called for the development of AI to be slowed.

However, US President Donald Trump has dismissed concerns over the rapid development of AI as a “hoax” and a “conspiracy”, arguing that slowing the technology could allow China to gain an advantage.
