Amazons new kiva systems

Today i watched a video about amazons new kiva systems. I think this is very interesting because these little robots run along a track delivering packages throughout the warehouse. I think this is the future of buying stuff online. These systems have improved amazons stock and created a lot of new job. I think these systems will one day take over the whole shipping process so people wont have to do any work. I see big things happening in the next 10 to 20 years with these machines and i hope they continue progressing as time goes on.
