Greetings!
I think you were right to give your honest opinion. This is what the topic seems to call for. This is especially true since the question asks "to what extent do you agree or disagree" with the statement. That gives you some latitude for examining both sides of the issue. I'm assuming that your essay stated the ways in which personal communications and people skills might be affected, then gave reasons for the opposing views as well. Like most issues today, this one is complicated and there are no easy answers. As long as you clearly stated your true opinion, you should be just fine.
Thanks, and good luck!
