No smartphone means no cheap bus fares for teens | Brief letters

I am delighted about the campaign to reduce smartphone usage among under-14s (‘The crux of all evil’: what happened to the first city that tried to ban smartphones for under-14s?, 7 May) but in West Yorkshire, where I work, we have run up against structural issues that make this impossible. The cheapest young person’s bus fares are only available via an app, which requires a smartphone. You can buy a monthly bus pass on a smartcard, but only in person and at limited locations. If your child needs a smartphone to get the bus to school, any hopes of not buying them one fall at the first hurdle.

Australia has been hesitant – but could robots soon be delivering your pizza?

Robots zipping down footpaths may sound futuristic, but they are increasingly being put to work making deliveries around the world – though a legal minefield and cautious approach to new tech means they are largely absent in Australia.Retail and food businesses have been using robots for a variety of reasons, with hazard detection robots popping up in certain Woolworths stores and virtual waiters taking dishes from kitchens in understaffed restaurants to hungry diners in recent years.Overseas, in jurisdictions such as California, robots are far more visible in everyday life. Following on from the first wave of self-driving car trials in cities such as San Francisco, humans now also share footpaths with robots.Likened to lockers on wheels, companies including Serve Robotics and Coco have partnered with Uber Eats and Doordash, which have armies of robots travelling along footpaths in Los Angeles delivering takeaway meals and groceries

AI firms warned to calculate threat of super intelligence or risk it escaping human control

Artificial intelligence companies have been urged to replicate the safety calculations that underpinned Robert Oppenheimer’s first nuclear test before they release all-powerful systems. Max Tegmark, a leading voice in AI safety, said he had carried out calculations akin to those of the US physicist Arthur Compton before the Trinity test and had found a 90% probability that a highly advanced AI would pose an existential threat. The US government went ahead with Trinity in 1945, after being reassured there was a vanishingly small chance of an atomic bomb igniting the atmosphere and endangering humanity.In a paper published by Tegmark and three of his students at the Massachusetts Institute of Technology (MIT), they recommend calculating the “Compton constant” – defined in the paper as the probability that an all-powerful AI escapes human control. In a 1959 interview with the US writer Pearl Buck, Compton said he had approved the test after calculating the odds of a runaway fusion reaction to be “slightly less” than one in three million

Paul McCartney and Dua Lipa among artists urging Starmer to rethink AI copyright plans

Hundreds of leading figures and organisations in the UK’s creative industries, including Coldplay, Paul McCartney, Dua Lipa, Ian McKellen and the Royal Shakespeare Company, have urged the prime minister to protect artists’ copyright and not “give our work away” at the behest of big tech.In an open letter to Keir Starmer, a host of major artists claim creatives’ livelihoods are under threat as wrangling continues over a government plan to let artificial intelligence companies use copyright-protected work without permission.Describing copyright as the “lifeblood” of their professions, the letter warns Starmer that the proposed legal change will threaten Britain’s status as a leading creative power.“We will lose an immense growth opportunity if we give our work away at the behest of a handful of powerful overseas tech companies and with it our future income, the UK’s position as a creative powerhouse, and any hope that the technology of daily life will embody the values and laws of the United Kingdom,” the letter says.The letter urges the government to accept an amendment to the data bill proposed by Beeban Kidron, the cross-bench peer and leading campaigner against the copyright proposals

‘Tone deaf’: US tech company responsible for global IT outage to cut jobs and use AI

The cybersecurity company that became a household name after causing a massive global IT outage last year has announced it will cut 5% of its workforce in part due to “AI efficiency”.In a note to staff earlier this week, released in stock market filings in the US, CrowdStrike’s chief executive, George Kurtz, announced that 500 positions, or 5% of its workforce, would be cut globally, citing AI efficiencies created in the business.“We’re operating in a market and technology inflection point, with AI reshaping every industry, accelerating threats, and evolving customer needs,” he said.Kurtz said AI “flattens our hiring curve, and helps us innovate from idea to product faster”, adding it “drives efficiencies across both the front and back office”.“AI is a force multiplier throughout the business,” he said

Leave them hanging on the telephone | Brief letters

Regarding dealing with cold callers (Adrian Chiles, 7 May), it’s irritating I know, but if you don’t mind your phone being inaccessible for a few minutes, why not say: “Hang on, I’ll go and get him/her”, and then leave your phone until the caller rings off? At least you will have wasted some of their day.Robert WalkerPerrancoombe, Cornwall Re fostering a love of reading in children (Letters, 6 May), one of my fondest memories of my teaching career was story time in the infant class in a local village school. Most of the children came quite a distance on buses. They adored Michael Rosen’s poetry. There were many afternoons when it was home time and they would shout: “Please read another Michael Rosen one, Mrs Mansfield, the driver won’t mind waiting
