[...] warehouses are potentially a source of vast amounts of employment for less-skilled Indians (of which there are hundreds of millions). Yet the falling cost of simple robotics and the increasing power of computing means that many of those jobs may never be created. Instead a very small number of highly skilled Indian programmers may earn a good living writing code to control the robots who travel the great aisles within these warehouses, moving around goods shipments that might otherwise have been handled by human workers.
