Life is about to change on the remote island nation of Tuvalu. To great fanfare, Tuvalu – an entirely cash-based society – has unveiled its first ever ATM, marking its move towards financial modernisation. But while the 10,000 people living in that country may be celebrating no longer having to queue at the bank, I fear their happiness will be short-lived. The world's first ATM was introduced in Britain in 1967, but for me the tyranny of machines that promise convenience but erode human contact really began about 20 years ago, in the form of self-checkouts in our local Sainsbury's. Having watched the Terminator movie franchise during my formative years, I railed prophetically against them, aware that it was just a small slippery slope from "unexpected item in the bagging area" to the extinction of the human race.

Tuvalu's foreign minister, Simon Kofe, told the COP27 climate summit yesterday that Tuvalu would look to the metaverse to preserve its culture and history. With global temperatures expected to rise as much as 2.8 degrees Celsius by the end of the century, the Pacific island nation is particularly vulnerable to rising sea levels. At last year's COP26 summit, Kofe addressed the conference while standing knee-deep in seawater to highlight the climate change threat. Climate scientists anticipate the entire country will be underwater by the end of the 21st century. Addressing the climate summit, Kofe said: "As our land disappears, we have no choice but to become the world's first digital nation. Our land, our ocean, our culture are the most precious assets of our people. And to keep them safe from harm, no matter what happens in the physical world, we'll move them to the cloud."

In 2015, I visited Fiji, Kiribati, and Tuvalu, which had just been hit by a cyclone. There, I learned a slogan -- "1.5 to stay alive" -- which refers to the 1.5 degrees Celsius (2.7 degrees Fahrenheit) threshold for global warming that, in theory, would avoid disastrous consequences. People living on the Pacific islands are well aware of the grave threat to humanity posed by climate change. Six months later, I met these new comrades again at climate negotiations in Paris. While speaking at an event, I referred to "1.5 to stay alive".
