Greetings!
You'll want to decide which side of the issue you're on. Let's say you choose "it enables people to come together." You might say something like "More than ever before in the history of the world, people have the opportunity to communicate across great distances, thanks to advances in technology." Or, if you wanted to take the other side, you might say, "Although technology does wonderful things for people, it also enables them to isolate themselves by giving them access to music, news, research materials, games, and shopping for anything they could want, without ever leaving the house."
I hope this helps you get started!
Thanks,
