This is a great question to ask in this day and age. You only need to have a look at the way in which people are permanently attached to their mobiles and Ipads to see ways in which we are too attached to technology. Here are three arguments that you could use to support such a position:
1) Note the way that more and more people do not wear simple things like wrist watches, as they have the time on their mobile phones. Watches are fast becoming anachronistic.
2) You also might like to think about the way in which knowledge and our relationship with it is changing. When I was younger, we used to have to learn lots of facts off by heart. Now, children don't learn such things off by heart as what they want to know is instantly obtainable on the web.
3) Lastly, just ask yourself how many times a day you and your friends go online. I go online during the course of a normal working day at least 10 times, and I use the internet to carry out my job as a teacher as well as to communicate with friends and to buy stuff. More and more every day actions are becoming dependent on the internet.
