In a significant policy shift, Google has updated its AI ethical guidelines, removing commitments to avoid using AI for harmful applications like weapons and surveillance. Senior executives James Manyika and Demis Hassabis asserted that businesses and democracies should collaborate on AI to enhance national security amid a complex geopolitical landscape. The revised guidelines come as Google aims to expand its AI deployment and invest $75 billion in AI projects this year, despite reporting weaker-than-expected earnings. The change reflects a growing trend in Silicon Valley toward defense technology partnerships, particularly against the backdrop of geopolitical tensions.
