In his (very, very long) book 'The Rise and Fall of American Growth' (https://rob.al/2sBaEBR), Robert Gordon lays out an argument that not only is growth slower than than people think, but that the growth spurt from 1870 to 1970 was, by all accounts, a one-off, and growth today is reverting back to the long term mean. Xi Jinping doesn't buy that, arguing that IOT, blockchain, AI, quantum and mobile computing are poised to drive a new spurt of growth which will exceed even that triggered by the industrial revolution. Only time will tell who's right.
