The eccentric engineer - [network history]

THOSE OF YOU who haven??t been to South Africa might be alarmed at the idea of turning left at the robots. The image conjured is an uneasy one ?? of street corners inhabited by listless mechanical men brimming with technology but with so little purpose that they can be used as landmarks when giving directions. Of course, South African robots are not mechanoids but simply the local term for traffic lights, which came as something of a disappointment to me, I must admit. Not that the invention of the traffic light should be dealt with too, er, lightly.
