Google revises its AI ethics guidelines, ending its ban on weapons and surveillance. The policy shift ignites debate over national security and tech responsibility.

Google just scrapped its pledge to avoid AI in weapons and surveillance, signaling a major shift in policy after Trump's inauguration.

Alphabet Inc., the parent company of Google, has removed a key commitment from its artificial intelligence (AI) ethical guidelines, dropping a previous pledge not to pursue technologies that could “cause or are likely to cause overall harm,” including weapons development and surveillance tools.
