They hope to identify patterns of brain activity that explain various properties of conscious experiences, such as changes in electrical signals or blood flow to different regions. The goal is to go beyond looking for mere correlations between brain activity and consciousness, and try to come up with explanations for its individual components.Prof Seth, the author of a book on consciousness, Being You, worries that we may be rushing headlong into a society that is being rapidly reshaped by the sheer pace of technological change without sufficient knowledge about the science, or thought about the consequences.

"We take it as if the future has already been written; that there is an inevitable march to a superhuman replacement," he says."We did not have these conversations enough with the rise of social media, much to our collective detriment. But with AI, it is not too late. We can decide what we want."But there are some in the tech sector who believe that the AI in our computers and phones may already be conscious, and we should treat them as such.

Google suspended software engineer Blake Lemoine in 2022, after he argued that AI chatbots could feel things and potentially suffer.In November 2024, an AI welfare officer for Anthropic, Kyle Fish, co-authored a report suggesting that AI consciousness was a realistic possibility in the near future. He recently told The New York Times that he also believed that there was a small (15%) chance that chatbots are already conscious.

One reason he thinks it possible is that no-one, not even the people who developed these systems, knows exactly how they work. That's worrying, says Prof Murray Shanahan, principal scientist at Google DeepMind and emeritus professor in AI at Imperial College, London.

"We don't actually understand very well the way in which LLMs work internally, and that is some cause for concern," he tells the BBC.Sam's parents said he was "adored by his family" and described him as "loyal, funny and fiercely protective".

They added the Race Across the World experience "opened Sam's eyes to the wonder of adventure".Sam's uncle Jonny Dunlop, told the BBC: "What you saw was what you got. Sam loved gardening, animals and doing physical activity."

Mr Dunlop said his sister Jo and Sam had a "special relationship" and were an "enormous hit on the show", adding: "The public really loved them."In a statement, a Race Across the World spokesperson, said: "Everyone who worked with him and indeed everyone who watched Sam could see just how precious and transformative the trip was for both him and his mum, Jo.
