Without doing your job for you, I would say the quick answer is to research what the Amish religious group says about technology and the "Luddite" (anti-tech) philosophy.
Once you've done that, figure out what the POSITIVE aspects of tech are...and find the NEGATIVE part of the POSITIVE. Nothing is 100% "good"...every good action has a negative consequence associated.
Example: Exercising is "good for you", right? Well, sort of...You can't overdo it or you risk heart attack. Also, in order to exercise you have to "give up" doing something else. So while you're exercising, you give up family time (unless it's a family bike ride). Or you skip that household repair project.
Technology makes it possible to be more "connected" to everyone than ever before but while you're in front of the screen, you can't be actually PHYSICALLY talking to them. Also even though the Internet is 24/7, humans have limitations of sleep needed. You can't spend all night studying on the Internet to get smarter because then you sleep through and bomb the test the next morning. These are obviously quick not-fleshed-out answers, but this should give you a start to how to think about your arguments.
Good luck!
