Artificial intelligence has given surveillance cameras the ability to recognise and track what they see, yet researchers are now demonstrating how AI can also be turned against those systems, creating patterns that leave people and vehicles perfectly visible to humans while potentially making them much harder for automated surveillance to detect.

A new attack technique could allow criminals to plant false information inside an AI agent’s long-term memory, potentially influencing decisions weeks or months later and creating a new security problem as businesses increasingly give AI systems greater autonomy.

A major UK study has found that some teenage boys are developing romantic and emotionally intimate relationships with AI chatbots, prompting growing concern among researchers, parents and regulators about how these increasingly human-like systems may be shaping young people’s understanding of relationships.

The artificial intelligence boom has attracted extraordinary levels of investment, transformed technology markets and created expectations of a new era of productivity, but a warning from the world’s leading central bank organisation suggests that the consequences could be felt far beyond the technology industry if financial returns fail to match the hype.
