I can’t have been the only one who was delighted when Barack Obama outed himself as a Trekkie while on the campaign trail last year, flashing Leonard Nimoy the Vulcan salute and assuring a Wyoming audience that despite his criticism of the bloated Nasa budget, the space programme was important to him: ‘I grew up on Star Trek. I believe in the final frontier,’ he told them. My president's a geek. More than that, Star Trek is a celebration of curiosity and self-improvement – and not a little socialist. Money has been abolished by the 24th century: ‘The acquisition of wealth is no longer the driving force in our lives. We work to better ourselves and the rest of humanity,’ says Captain Picard. But an old piece in the LRB by Tom Shippey says that I have it wrong.
