In May, computer scientist Geoffrey Hinton, known as the “godfather of AI”, quit his role at Google to warn of the “existential threat” posed by artificial intelligence. The Center for AI Safety followed up with an open letter, signed by Hinton and hundreds of others, warning that advanced AI could destroy humanity.  “Mitigating the risk of extinction from AI should be a global priority,”  read the statement. This sudden surge of concern seems to have been motivated by the rapid advance of AI-powered chatbots like ChatGPT and the race to build more powerful systems. The fear is that the tech industry is recklessly a...

  How does ChatGPT work and do AI-powered chatbots “think” like us? The large language models behind the new chatbots are trained to predict which words are most likely to appear together – but “emergent abilities” suggest they might be doing more than that 25 July 2023 By  Edd Gent Illustronaut/Alamy The current whirlwind of interest in  artificial intelligence  is largely down to the sudden arrival of a new generation of AI-powered chatbots capable of startlingly human-like text-based conversations.

Overnight, millions gained access to an AI producing responses that are so uncannily fluent that it has been hard not to wonder if this heralds a turning point of some sort. There has been no shortage of hype. Microsoft researchers given early access to GPT4, the latest version of the system behind ChatGPT, argued that it has already demonstrated  “sparks”  of the long-sought machine version of human...
