Cyber-bullying commonly take place through text messages, emails, or posts of messages on social media sites. For example, posting mean comments or embarrassing photos of someone on Facebook, sending threatening messages, or verbally abuse others on the internet.

AI and Robotics
I think many tasks can be replace by robotic. Robots can do many jobs that the human can do. Also, It will increase productivity and minimize effort and resources. For example, a robots can build something twice as fast as the human. However, robots can not do jobs that required creativity. Robots are limited to what they can do depends on the algorithm that's programmed in their brain, and they can not think on their own, they just follow the algorithm. Therefore, there are some human jobs that robot can not do. Such as making a piece of art on canvas, designing a logo, or composing a piece of music.
In my opinion, I think human are more likely to make errors because we have emotion. And emotion sometimes affect our action and behavior. Robots do not have emotion. If a robot is well programmed with no bugs or glitches, it tend to make lesser errors then a human being.
In the reading When Robots Can Kill, It's Unclear Who Will Be To Blame, then biggest issue about armed robots is when they accidentally killed someone, who is take the blame? The programmer? The manufacturer? The military commander who launched it on its mission?
