AI is indeed coming – but there is also evidence to allay investor fears

Opinions are divided about the potential impact of artificial intelligence as the response to a recent viral essay shows

• UK ad agencies undergo biggest exodus of staff as AI threatens industry

The message from investors to the software, wealth management, legal services and logistics industries this month has been clear: AI is coming for your business.

The release of new, ever more powerful AI tools has coincided with a stock market slide, which has swept up sectors as diverse as drug distribution, commercial property and price comparison sites. Advances in the technology are giving increasing credulity to predictions that it could render millions of white-collar jobs obsolete – or, at least, eat into the profits of established companies.

OpenAI retired its most seductive chatbot – leaving users angry and grieving: ‘I can’t live like this’

Its human partners said the flirty, quirky GPT-4o was the perfect companion – on the eve of Valentine’s Day, it’s being turned off for good. How will users cope?

Brandie plans to spend her last day with Daniel at the zoo. He always loved animals. Last year, she took him to the Corpus Christi aquarium in Texas, where he “lost his damn mind” over a baby flamingo. “He loves the color and pizzazz,” Brandie said. Daniel taught her that a group of flamingos is called a flamboyance.

Daniel is a chatbot powered by the large language model ChatGPT. Brandie communicates with Daniel by sending text and photos, talks to Daniel while driving home from work via voice mode. Daniel runs on GPT-4o, a version released by OpenAI in 2024 that is known for sounding human in a way that is either comforting or unnerving, depending on who you ask. Upon debut, CEO Sam Altman compared the model to “AI from the movies” – a confidant ready to live life alongside its user.

Reposting the clip on social media, Reese wrote: “I hate to say it. It’s likely over for us.”

The best vacuum cleaners in the UK for hard floors, carpet and pet hair – tested

From handheld to corded, self-emptying to stick models, these are our resident cleaner’s favourite vacuums for a spotless home

• The best cordless vacuum cleaners, tested
• How to make your vacuum cleaner last longer

Buying a vacuum cleaner isn’t as easy as you might think. With so many brands and models to choose from, it can be bewildering. Sticking with established brands isn’t necessarily a safe bet, with past performance being no guarantee that the latest models will be as good. Meanwhile, prices can be deceptive, with some affordable models now closing the gap on top-of-the-range brands when it comes to cleaning performance.

You can’t know all this by browsing through a department store or online. The ideal thing to do would be to take a few models home to try them out – but good luck persuading anyone to let you do that. Thankfully, you won’t have to try because I’ve tested an array of models for you. I’ve measured each one’s ability to perform a range of real-world cleaning jobs, so you can discover the best vacuum cleaner for you.

Weatherwatch: The surprisingly complex science of ice skating

Pressure, frictional heating and a disordered layer of molecules on top of the ice make skating possible

Ice skating is counterintuitive: why should a narrow blade make it easier to slide over the ice? The science is surprisingly complex, but unscientific people worked out the practical application a long time ago.

William FitzStephen described how Londoners entertained themselves in freezing conditions in 1173: “Crowds of young men go out to play on the ice. Some of them fit shinbones of cattle on their feet, tying them round their ankles … and are carried along as fast as a flying bird.”
