As authorities around the world scramble to draw up guardrails for artificial intelligence, British Prime Minister Rishi Sunak warned Thursday against moving too fast on regulating the rapidly developing technology before it's fully understood. Sunak warned about acting too quickly even as he outlined a host of risks that AI could bring, from making it easier to build chemical or biological weapons to its use by terrorist groups to spread fear, or by criminals to carry out cyberattacks or fraud. Governments are the only ones able to keep people safe from AI’s risks, and it shouldn’t be left up to the tech companies developing it, he said in a speech ahead of a summit he’s hosting next week on AI safety.
