2%.Hong Kong’s Hang Seng index dropped 1.7%.Sundar Pichai, the head of Google’s parent company, Alphabet, said in an interview with the BBC that there was “irrationality” in the current AI boom.He warned that in the event that the AI bubble bursts, “no company is going to be immune, including us”.

Meanwhile JP Morgan Chase vice chairman, Daniel Pinto, said that booming AI valuations are due for a reassessment.“There is probably a correction there,” he said at the Bloomberg Africa Business Summit in Johannesburg on Tuesday.“That correction will also create a correction in the rest of the segment, the S&P and in the industry.”The chief executive of Klarna, Sebastian Siemiatkowski, also sounded the alarm this week, warning that huge sums being poured into computing infrastructure made him “nervous”.He told the Financial Times: “I think [OpenAI] can be very successful as a company but at the same time I’m very nervous about the size of these investments in these datacentres.

That’s the particular thing that I am concerned about,”The Klarna co-founder added that the rising valuation of AI companies, including the chipmaker Nvidia, was also a source of concern,Nvidia became the first company to hit a market value of $4tn this year, later followed by Apple and Microsoft,Sign up to Business TodayGet set for the working day – we'll point you to all the business news and analysis you need every morningafter newsletter promotion“That makes me nervous, because of the amount of wealth that is currently automatically allocated into this trend, without some more thoughtful thinking,” Siemiatkowski said,“You can say, ‘I disagree with the fact that Nvidia is worth that much and I don’t care, some rich people are going to lose some money.

’ But the truth is, because of the index funds and how this works, your pension right now is going into that theory that it is a good investment.”An AI bubble is now seen as one of the most serious risks in the stock market, and a survey by the Bank of America found that 45% of its polled fund managers believe it is the biggest tail risk.The price of gold, which is traditionally seen as a safe haven asset, is also falling.The spot price fell by 0.3% to $4,033.

29 an ounce on Tuesday morning, after earlier hitting its lowest level in a week.The drop comes amid fading expectations that the US Federal Reserve will cut interest rates next month.Higher interest rates make gold relatively less appealing as the metal does not pay a yield.However, Giovanni Staunovo, an analyst at the Swiss investment bank UBS, said the gold price was likely to fall further but would soon recover.“I would expect gold prices to bottom out soon, as I still see the Fed cutting rates several times over the coming quarters, and central banks’ diversification into gold remains strong,” he said.

Klarna says AI drive has helped halve staff numbers and boost pay

Klarna has claimed that AI-related savings have allowed the buy now, pay later company to increase staff salaries by nearly 60%, but hinted it could slash more jobs after nearly halving its workforce over the past three years.Chief executive Sebastian Siemiatkowski said headcount had dropped from 5,527 to 2,907 since 2022, mostly as a result of natural attrition, with departing staff replaced by technology rather than by new staff members.The figures add to the impact of an internal artificial intelligence programme, which had steadily reduced its use of outsourced workers including those in customer service, with technology now carrying out the work of 853 full-time staff, up from 700 earlier this year.It meant the company, which was founded in Sweden in 2005, had managed to increase revenues by 108% while keeping operating costs flat. Siemiatkowski told analysts on an earnings call on Tuesday that it was “pretty remarkable, and unheard of as a number, among businesses”

‘This wasn’t about money, this was a life at stake’: the world of a sports lawyer

Simon Leaf was sitting in the doctor’s office next to a footballer receiving news that would change the player’s life. The footballer knew something wasn’t quite right and medical tests had been ordered. This was not long after Fabrice Muamba had been saved by the speed of paramedics after having a cardiac arrest on the pitch at White Hart Lane, Leaf recalls, so tensions were heightened.As the player’s lawyer, Leaf was asked to attend when the worst was confirmed and the consultant revealed the player had hypertrophic cardiomyopathy – the same condition as Muamba, where the heart muscles thicken and blood is pumped less efficiently.“To get the results with him, to talk him through his options, to try to guide him through that process was a truly humbling experience,” Leaf says
