To the normal person who is scared of new things, they will never use it. EVER.
Remember, that everything is new at some point. I'm going to bring up Paypal. They were new when they first started and a lot of people didn't want to use them because they were sceptical. However, after time it becomes one of the most popular services used. Of course, some people are still sceptical.
As long as Bitcoin is presented in a good way and has enough tutorials and guidance and most importantly gets enough positive media attention then people will start to get interested.
