Bill Gates says unchecked AI could ‘cause a billion deaths’ in call for regulation

Bill Gates has called on the US’s federal legislators and law enforcers to regulate the development of artificial intelligence (AI), saying in an interview airing on Sunday that the technology left unchecked could cause “a billion deaths” and “no one thinks self-regulation is enough”. “You need law enforcement and the politicians to get into the discussion about what safeguards and monitoring look like,” the Microsoft co-founder and philanthropist said to Kristen Welker, the NBC Meet the Press host. “And that ha…

Bill Gates says unchecked AI could ‘cause a billion deaths’ in call for regulation

In brief

On 27 September 2026, The Guardian reported on Bill Gates's interview with NBC's Meet the Press host Kristen Welker, in which the Microsoft co-founder called for US federal legislators and law enforcers to require safeguards and monitoring for AI development, arguing self-regulation is not enough and warning that AI in the wrong hands could cause a billion deaths.

The warning matters because it frames AI as a dual-use capability comparable to a weapon and pushes the debate from voluntary industry measures to legally required oversight, while also highlighting existing contested uses of AI tools by militaries and immigration enforcement. What remains uncertain is what specific safeguards, monitoring mechanisms, and enforcement authorities would be required and whether they would prevent misuse without dramatically slowing development.

Main points

  1. Gates told NBC's Meet the Press that federal legislators and law enforcers must regulate AI development and that self-regulation is insufficient.
  2. He warned AI in the wrong hands could be powerful enough to cause a billion deaths and described it as a weapon when combined with ill intent.
  3. He said a kill switch alone is inadequate and that discussion of it shows how non-technical various people are.
  4. The interview followed a nearly 6,000-word essay he published in late August warning about AI's potentially lethal large-scale harms.

The problem

Unchecked development of AI could enable people with ill intent to cause mass-casualty events on the scale of a billion deaths, requiring federal safeguards and monitoring beyond self-regulation.

The rundown

The piece reports on an NBC Meet the Press interview airing Sunday 27 September 2026 where Gates said regulation will be 'a little bit of overhead for the industry – but not a dramatic slowing'. It notes similar calls for slowdown from Sam Altman and Elon Musk and cites Senator Bernie Sanders proposing legislation on 23 September to temporarily pause advanced AI development while guardrails are put in place.

It also contextualizes Microsoft's own role, citing a Guardian essay by No Azure for Apartheid authors who said the Israeli military 'has used AI tools to kill in Gaza' and that the US Department of Homeland Security 'has used AI tools such as Microsoft’s Azure to monitor, arrest and deport immigrants en masse'. The article notes this was among Gates's first major public appearances since an external review related to Jeffrey Epstein.
