Why couldn't they have made it a turtle, turtles are nice, and they kept showing turtles all through the movie. What the hay?
What hump?
It looked more like a cockroach. The 'boss' robot probably was inspired by them as they were in the desert. Note that Cleo plays with one when at the cave.
shareWhat is wrong with you? The worst part in the movie is the robots never picking up a gun and shooting. Even knowing how smart and fast learners they are. So it was good that FINALLY the spider robot attacked a human. A turtle moves too slow, could never attack a human.
shareThe problem in your thought process is that you equate intelligence with violence.
Maybe intelligence is the realization that any specific individual is not important, but only the survival of the species is.
It is important to note that not every species puts emphasis on the individual as we do and that maybe another form of intelligence would put emphasis on hive mentality.
Not to mention, in the case of robots, what use is the individual if there's a free and constant flow of information between them? The individual becomes superfluous, only the information matters. It doesn't seem to be the case in this movie though, I'm just making the case that the use of violence to defend oneself doesn't necessarily make sense in every possible configuration of intelligent societies/beings.
