# Fearing rogue AI may kill humans in near future, researcher quits Anthropic > Source: > Published: 2026-09-10 11:13:47+00:00 In one line An AI researcher quit Anthropic over fears that unchecked AI development could lead to human extinction. I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives.

The very people building this technology admit that it could threaten the future of humanity. That is why I will soon be introducing legislation to ban superintelligence and pause AI development.

It's becoming more clear the threat AI poses to humanity, so I'm calling for immediate action from the industry and Washington.
