A computer scientist who revolutionised the use of artificial intelligence (AI) has called for the UK to be "brave" in its pursuit of the technology.

Llion Jones from north Wales, who was part of the pioneering Google team that unlocked AI's ability to respond in a human-like form, warned against trying to compete with "hyper-scalers" in the USA and China.

He said the "sycophantic" responses of the current wave of AI chatbots needed to be fixed.

"We need to make AIs that can actually disagree with you, and actually correct you," he said.

Mr Jones is one of the co-authors of the 2017 paper Attention Is All You Need, which introduced the Transformer architecture that put the "T" in ChatGPT. It was a breakthrough that now underpins the generative AI systems that are transforming business and everyday life.
