Summary

Global AI stocks declined on Monday following endorsements from major companies like Microsoft, OpenAI, Anthropic, and SpaceXAI to slow down the development of advanced AI models. This shift towards a more cautious approach is causing concern among investors who fear reduced spending on computing resources could stall the current investment boom in AI technology. Despite these calls for restraint, some companies continue to push ahead: Anthropic announced it expects its second consecutive profitable quarter, while OpenAI ruled out an IPO this year.

Story summary

Dario Amodei, CEO of Anthropic, called for competitors to agree on third-party evaluators to ensure AI safety during an interview with CBS News. The push follows concerns about the rapid development and potential risks of artificial intelligence, such as models becoming too powerful within six to 12 months. Notable figures like Sam Altman (OpenAI) and Elon Musk voiced support for this idea. However, these calls have led to stock market declines in tech companies like Nvidia and AMD. Additionally, some critics argue that focusing on existential risks distracts from the immediate harms of existing AI technologies, such as energy consumption and job displacement.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
