The reason there are no humanlike robots is not that the very idea of a mechanical mind is misguided. It is that the engineer- ing problems that we humans solve as we see and walk and plan and STANDARD EQUIPMENT make it through the day are far more challenging than landing on the moon or sequencing the human genome. Nature, once again, has found ingenious solutions that human engineers cannot yet duplicate. When Hamlet says, "What a piece of work is a man! how noble in reason! how infinite in faculty! in form and moving how express and admirable!" we should direct our awe not at Shakespeare or Mozart or Einstein or Kareem Abdul-Jabbar but at a four-year old carrying out a request to put a toy on a shelf. In a well-designed system, the components are black boxes that per- hy are there so many robots in fiction, but none in real life? I form their functions as if by magic. That is no less true of the mind. The would pay a lot for a robot that could put away the dishes or faculty with which we ponder the world has no ability to peer inside W run simple errands. But I will not have the opportunity in itself or our other faculties to see what makes them tick. That makes us this century, and probably not in the next one either. There are, of course, the victims of an illusion: that our own psychology comes from some robots that weld or spray-paint on assembly lines and that roll through divine force or mysterious essence or almighty principle.

The problem is humblingly difficult. the help of cinematic conventions like fish-eye distortion or crosshairs. First, a visual system must locate where an object ends and the back- That is fine for us, the audience, who already have functioning eyes and drop begins. But the world is not a coloring book, with black outlines brains. But it is no help to the robot's innards. The robot does not house around solid regions. The world as it is projected into our eyes is a mosaic an audience of little people—homunculi—gazing at the picture and of tiny shaded patches. Perhaps, one could guess, the visual brain looks for telling the robot what they are seeing. If you could see the world through regions where a quilt of large numbers (a brighter region) abuts a quilt of a robot's eyes, it would look not like a movie picture decorated with small numbers (a darker region). You can discern such a boundary in the crosshairs but something like this: square of numbers; it runs diagonally from the top right to the bottom cen- 225 221 216 219 219 214 207 218 219 220 207 155 136 135 ter.
