Shares in Japanese investment conglomerate SoftBank Group, a major investor in OpenAI, plunged more than 10% on Monday, alongside other technology shares, after executives at some of the world’s leading AI companies backed calls to prioritise “caution over speed and prudence over profit”.

The phrase was used by Anthropic CEO Dario Amodei, who called on Saturday for AI companies to “pace the frontier” through a coordinated slowdown in the development of their most advanced models, allowing more time to understand and manage the risks.

Among his main concerns is so-called “recursive self-improvement”, in which AI systems help to build the next generation of AI models.
