Brtiain must look abroad to sustain Tech City It's maybe a cliché but nevertheless it's the truth: if you want to be the best then you have to employ the best. If you don't then not only Silicon Valley, but other European competitors like Berlin and Stockholm will. The US technology sector has a whole continent to recruit its workers from but still it employs great talents from the outside world. You only have to look at Apple's head of design, Britain's own Sir Jonathan Ive to see that is true. This would be a tragedy, if we missed such opportunity, as I truly believe that Britain is on the cusp of a great things. All the ingredients are in place at the moment to become a world beater in technology, not just an entrepreneurial spirit but infrastructure, investment and government support too. But you need to strike while the iron is hot and Britain is hot, but waiting for a homegrown workforce to be trained up would be a disaster. By hiring foreign players, the Premiership has raised the standard for everybody and become one of the world's, if not the world's, greatest football league. I already feel that London is closer to Silicon Valley than New York and anywhere in Europe but it needs a free flow of talent. Not just technology engineers but lawyers, investors and venture capitalists too. Despite improvements in communication it is still very important to bring people together if you want to be creative. Physical proximity is as important as ever. It is a case of attracting the most competent people and for them to come together in one place and create a critical mass. People really should be able to go to a barbecue and come back with a new business idea. There is no doubt London is strong. It is getting to the stage where a start-up in London has almost as good a chance to succeed as one in Silicon Valley. But the promise of London will fail if you can't attract competent people, and that means from all over the world.
