"Life is a circle".

That's a statement which I think relevant with this video. First, let's we talk about this entire video. Wall-E is a robot that has function to collect many rubbish into a little square. Wall-E is the last robot which still alive in the Earth while all humans had gone with a big plane and live there. 

This video performs us about ubiquitous computing. Ubiquitous computing is an advance computing concept where computing is made to appear everywhere and anywhere. High-technology era causes a lot of new technology and new gadget created. It might be a good news for technology evolution but it could be a bad news for our Earth. That's not impossible to make 'high-technology' is a good news both of technology evolution and our Earth. It will happen if humans keep paying attention to the environment. 

Now, let's go to our topic "Life is a circle".

As we know that a long long time ago humans lived without knew anything about technology. Because of curiosity, humans could create a lot of technology in the Earth. But, we have to realize that human never feel satisfied. It encourages human to create a lot of gadget without care with the environment. When humans arrive at one point, humans will realize that they need Earth. Many people start keeping the environment with leave the technology. This is a circle, isn't it?
