Cummings has left behind a No 10 deluded that Britain could be the next Silicon Valley | David Edgerton

Talk of moonshots' is typical of the belief that the UK is an innovative state - but it's far from it

Though many have speculated on what Dominic Cummings's legacy" might be, one of the more significant contributions he made to No 10 was his thinking about science and technology. Prime ministerial speeches have been peppered with passe futuristic slogans about how Britain leads the world in quantum computing, genomics and AI, and promises that the country can be a science superpower" - notions that Cummings made a central part of the Brexit project.

Like many a macho innovation guru, Cummings is an amateur not a professional, an artless nerd and not an expert. That his policies and prescriptions have been taken seriously is a measure of our collective credulity about Britain's place in the world of innovation. But whether this foolishness will leave with the fool is another matter.
