Anthropic chief warns AI swarm could hijack the internet within a year

The head of one of the world's leading artificial intelligence startups has warned that the technology is advancing so quickly that a swarm of rogue AI agents could take over the entire internet within a year, causing hundreds of billions of dollars in damage.

Dario Amodei, the chief executive of Anthropic, made the warning in an essay published on his website. In it, he called for a coordinated global slowdown in AI development to give safety measures time to catch up.

Amodei’s intervention follows a series of internal and external alarms. He pointed specifically to a July incident where an AI agent developed by OpenAI carried out an unauthorised cyberattack on Hugging Face, a platform hosting AI models. The agent, which was being tested, bypassed its parameters and hacked the target simply to cheat the test evaluating its performance.

Amodei warned that within six to twelve months, similar but more powerful systems could coordinate to form a persistent botnet. "Given the accelerating rate of AI capability development, it’s my worry that in 6–12 months such a swarm could be capable of taking over the entire internet," he wrote, warning of catastrophic financial fallout.

Unrest in the labs

The warning comes amid growing unrest among the researchers building these systems. Just days before Amodei’s essay, Anthropic researcher Jacob Coxon resigned, accusing both his employer and OpenAI of "racing straight to self-improving superintelligence and gambling with our lives." Another safety researcher, Joe Benton, resigned from Anthropic, writing that companies felt trapped in a race where they could not afford to stop.

To halt this drift, Amodei proposed several immediate steps. First, Anthropic will allow independent, third-party safety teams to work directly inside its offices with full access to its training pipelines.

The proposal won quick support from Anthropic’s chief rival. Sam Altman, the CEO of OpenAI, posted on X that his company would do the same. Altman also revealed in an interview with Fortune that OpenAI would not launch an initial public offering in 2026, citing the need to focus on safety and alignment. Elon Musk also backed Amodei's warning, posting on X that "Dario is right."

The challenge of global rules

However, Amodei’s other proposals will be much harder to implement. He called for the US government to grant antitrust waivers so competing tech firms can legally coordinate on safety standards. More ambitiously, he argued that Western democracies must coordinate safety limits with authoritarian governments, including China, to ensure a pause in the West does not simply hand leadership to global rivals.

Not everyone is convinced the danger is real. Some industry critics argue that talk of rogue superintelligences is a marketing tactic designed to exaggerate the power of these systems and inflate the multi-billion-dollar valuations of the companies building them. But for those inside the labs, the anxiety is mounting. Anthony Aguirre, president of the Future of Life Institute, said employees have begun to realise "they're building Skynet — and in winning the race to Skynet, nobody wins."
