Artificial intelligence

I miss daydreaming. It’s a small problem to have in a pandemic, but it nags at me. Laptop, cooker, home-school, broom. ‘Mum, Mum, Mumma, Mum… You’re not looking, Mum. You have to look!’ The gap between things seems to have disappeared. There’s no time to drift and wander. I look at my phone too much, and sometimes I have the strange feeling my brain is suffocating. And I might not have thought this worth mentioning were it not for a new book, When Brains Dream, by a pair of American sleep scientists, Antonio Zadra and Robert Stickgold. Bob and Tony, they call themselves throughout the book, and if they’re right,

Sir Roger Penrose was at school when he realised that his mind worked in an unusual way. ‘I thought, maybe when I go to university, I’ll find people who think like me,’ he tells me, at the beginning of what was to be a fascinating conversation, stretching long into the afternoon. ‘But it wasn’t like that at all. When I would talk to someone about an idea, I found myself not understanding a word they were saying.’ Just after we spoke, in early December, Penrose received the Nobel Prize in Physics, so perhaps it’s no surprise that he should think a little differently. But, as he explained it to me,

Every ten to 15 years there is a technology breakthrough that really changes what it means to be human. The internet, mobile phones, social media and, most recently, AI voice assistance: all of these amplify the human experience. And with each technological game-changer we go through much of the same series of questions and anxieties. We worry both that it’s all too much, and too little. With the recent advances in artificial intelligence we leap ahead to the existential dangers, and at the same time wonder whether there aren’t more pressing issues to discuss: healthcare, climate change, education, the economy. Well, they are pressing issues — but AI has an

‘There is a profound mismatch between the way we are educating our young and the world we’re educating them for, and what should, and could, be happening.’ So says Sir Anthony Seldon, former headmaster of Wellington College and vice-chancellor of Buckingham University. Seldon is well known for promoting novel ideas when it comes to education. During his time at Wellington he was often in the limelight for his original style of thinking, or ‘visions for education’ as he puts it; for example, his decision to introduce mindfulness into the curriculum there. Seldon isn’t just a teacher, though. He’s also a historian and a political biographer, as well as being a

‘I’m a nice person,’ said the robot. ‘I just hate everybody.’ Maybe you know the feeling. The robot in question was Microsoft’s first great experiment in artificial intelligence, given the tone of a teenage girl and the name of Tay. The plan was for it — her? — to lurk on social media, Twitter mainly, and listen, and interact, learn how to be a person like everybody else. On a public-relations level, at least, the experiment did not go swimmingly. ‘Gas the kikes, race war now!’ Tay was tweeting, after about a day. Big Hitler fan, it turns out. Not so fond of anybody else. ‘Why are you racist?’ somebody

There’s something wrong with the relationship between patients and their GPs. I’ve spent much of this winter in my local surgery, what with one thing and another, sitting among the stoic and snivelling, drifting between different doctors. They’re pleasant, if perfunctory, but with each visit I became more sure that something fundamental is awry. The docs seem ill at ease, as if their collective nose is out of joint, and I don’t think it’s overstretching or underfunding that’s the problem. My unprofessional diagnosis is that there’s a change under way in the balance of power between patients and medics; the status of GP as unimpeachable oracle is under threat, he

Having written (for a Times diary) a few sentences about consciousness in robots, I settled back to study readers’ responses in the online commentary section. They added little. I was claiming there had been no progress since Descartes and Berkeley in the classic philosophical debate about how we know ‘Other Minds’ exist; and that there never would be. A correspondent on the letters page referred me to Wittgenstein’s treatment of the subject and so I studied his remarks. I have to confess they are, to me, unintelligible. But I cannot let the matter rest. My earlier thoughts had been prompted by newspaper reports of the adventures of a talking, hitchhiking

The latest US census found that 43 per cent of the population in Santa Clara County, California, were members of a religious institution. This is slightly less than the American national average of 50 per cent, but you’d probably expect that because the area includes Silicon Valley, where geeks are busy designing our online, gadget-laden future. You might assume they would be pretty secular types. You’d be wrong. As a measure of religious observance, that census is useless. Perhaps the geeks don’t all belong to churches, but the reality is that the inhabitants of the Valley are in the grip of a religious mania so bizarre, so exotic, that it makes the
