Bitcoin infrastructure questions

Hi guys,

I have been looking at this forum for nearly a year now but just don't post usually.

My questions are:-

What bitcoin infrastructure needs to be built next for bitcoin to mature and be adopted by non tech savvy people?

How has bitcoin grown over 2014 and with regards to merchants accepting btc compared to 2013?

What is the next step for bitcoin? More merchants? Easier transactions or is security more of a priority?

I am just trying to put together everything I have been reading here for months on end and would like to know what is needed to be done to make the average folk understand the concept of bitcoin and get involved in it.
I try to talk to family and friends about it and I get the usual 'glazed' over look and the "oh right" feedback. I am pretty sure it's not the way I put it across to them, it's their sheep like attitude of following the crowd.

I think a lot of people don't think outside the box. More people need to be open minded in my opinion. It's very frustrating.

I am wondering what the turning point will be when people will eventually realise this is a very good thing and will be revolutionary to the way we live everyday life.

Thank you in advance.

Russell
