I think medium and technology are very important in our lives. Because they must to play an very important role around our lives , including lives, environment, everywhere around us. All of the medium and technology let our lives more convenient, comfortable, relaxed………..Therefore , i have to say the medium and the technology are very important to us.
Let me get some example:
If we have newspaper ,we can understand many knowledge,read some articles, news that is good or bad.
If we have TV , we know everything what we wants to know and more clear and know the truths from the pictiue.
If we have computer and cell phone , we can communicate with a lot of friend even you and others have far distance.
If we have pencil, we can write something what we wants to say and let everybody knows what the meaning is .
If we have refrigerator, we can preseverence our foods.
If we have car, we can go everywhere what we wants to go, and we can very relaxed to arrive the destination.
So, medium and technology are important and play an important role.
Also, I think Maybe McLuhan’s Tetrad helps some ways of thinking and creative, he has four tetrads, it can help us to think many questions about medium and technology, because it different aspects, we can think more creatize ways and questions.
