• Business live – latest updates

Shares in semiconductor companies fell on Tuesday after the boss of Broadcom compared many AI investors to “casino” gamblers, and the Chinese memory chip maker CXMT said it had made good progress on a new chip architecture.

South Korea’s benchmark Kospi index tumbled 6.25% as investors dumped chip stocks, while other Asian markets were also lower. Japan’s Nikkei fell 1.8% and the Taiwan exchange lost almost 2%, with the country’s chip maker TSMC down by a similar amount.

The pioneering computer scientist on why Trump is using ‘superintelligence’ wrong, whether AI could wipe out humanity – and how our biggest challenge will be accepting we’re not the only intelligent beings

Donald Trump is a “corrupt, senile felon” whose fixation on the term superintelligence proves he knows nothing about AI, said Geoffrey Hinton, “godfather” of the technology, in a wide-ranging interview where he doubled down on recent warnings that AI models pose an existential threat to humanity and scoffed at claims the industry could regulate itself.

The pioneering computer scientist, whose work helped lay the foundations of modern AI, has since become one of the technology’s most vocal critics. His latest remarks come after a tumultuous month during which a growing list of senior AI scientists and researchers have joined Hinton in ringing the alarm about how the technology he helped create could ultimately escape human control, sparking an industry crisis, the hasty assembly of congressional meetings and a rare global consensus that something must be done.
