Before the pandemic struck, there was talk of a ‘Great Stagnation’ – the idea that the world economy was doomed to lacklustre growth and had hit a technological plateau with no game-changers in sight. But Covid - and lockdown - has changed all that. There was such doubt about the vaccines because it normally takes at least ten years to develop a successful immunisation. Now, we have six working ones. The innovation will not stop there: breakthroughs are happening at rapid speed, from transport and energy, to medicine and science, and even when it comes to currencies. Take transportation and energy. Last October, for example, Waymo finally announced the launch of a taxi service that is fully driverless and open to the public.
