The intentions of Wall-E robots

This week we watched the children’s movie Wall-E. I’ve watched this movie numerous times since it first came out, but this time I noticed a few things that I never noticed before. Of all of the Wall-E style robots at the beginning of the movie, Wall-E is the only one that’s still functioning. He repairs himself while the rest just stopped functioning. He collects things while the others just worked. He is somewhat sentient in a way that the other “Wall-E-bots” were never meant to. So how did Wall-E accomplish that? What made him special? I also realized that the Wall-E-bots were never intended to clean up the world. They were meant to simply move the trash out of the way so that people could have space. The people who built the robots actually wanted to clean up the world, they would have come up with a faster way to get things to decompose. Instead they compacted all the trash which will make it take longer to decompose because less of it is then exposed to the elements. Even in a post apocalyptic world, humanity tries to take the easiest possible way out, not necessarily the best way.
