‘One discovery changed the course of history forever. We learned to talk. Speech has allowed the communication of ideas, enabling human beings to build the impossible. Mankind’s greatest achievements have come about by talking. And its greatest failures by not talking. It doesn’t have to be like this. Our greatest hopes could become reality with the technology at our disposal, the possibilities are unbounded. All we need to do is to make sure we keep talking.’
Professor Stephen Hawking – quoted from the old BT advert on TV
