Match the words with pictures. ______ automation ______ nanobots ______ global warming ______ artificial intelligence (AI) ______ cloning 3 2 5 1 4 1 2 3 4 5 While most often when people think of a robot, they think of the android (human-like robot) in Picture 1, actually the vast majority of robots are like that in Picture 3, which is a robot arm used to assemble parts in a factory. In this activity, the robot arm in Picture 3 represents automation. Since an android is meant to be like a human in every way, the android in Picture 1 is being used to represent artificial intelligence (AI). Picture 2 is an artist’s rendering of nanobots in the human bloodstream. A nanobot is a microscopic robot. While they are still in the development stage, it is thought that in the future, nanobots can be used within the human body to deliver carefully targeted doses of medicine to areas in the body that need them and to repair human tissues and cells. Task2- Discussion How do you think these events or such technology might develop in the future? What challenges and opportunities might they bring? Challenges: With the development of Al, there may come a time when it becomes a real issue as to whether a computer or machine has in fact achieved consciousness, and whether, as a conscious being, it deserves the same rights as a human being. Opportunities: AI may help us solve problems that are currently too big and overwhelming for us to solve on our own. For example, complex Al models may be able to use given data to develop a workable solution to global warming.
