Bernard Levin in conversation with Sir Clive Sinclair 'Within the not-too-distant future, we may not be the most intelligent species on earth.' These are the words, not of a science-fiction writer, but SIR CLIVE SINCLAIR , whose list of technical advancements to date make his assertions hard to ignore. He introduced the first pocket calculator, the first digital watch, the first flat-screen pocket TV and helped raise the level of computer literacy in Britain with his range of affordable microcomputers. In this conversation he shares his view of the present day and his extraordinary vision of the future.
