Robots are still depending on...

After watching the movie made by National Geographic named "Aftermath: Population Zero." This got me wonder and want to share this to you.

Every videos I made, I made them without sound, I deleted them before I could upload video, because I didn't want to add any sound due to my deafness. Sometime I forgot to delete them, but, most of it didn't have sound. I had seen some people offered me different way, I still didn't want to put any sound. If you kept complaining about this, shut the hell up. To people who didn't mind, thank you.
