right that china has made great strides in handsets, in 56 technology, in artificial intelligence, in electric vehicles, just as she said. when i look at the technology race between china and the us, europe and others, i think there are five areas that are really important. they are artificial intelligence, semi conductors, which of course are the things that make all of computing power possible, the chips that power all of our computers. quantum computing, which is still further out. different aspects of biotechnology, and financial technology. in some of those areas, the west is still ahead, i would say in artificial intelligence, most of the academics doing the really cutting—edge work are in the uk, in the us, canada and elsewhere, but shirley is right. china is rapidly catching up.
