Like the old saying goes "you can't teach a old dog new tricks". This applies for crypto as well. A lot of people are just stuck in the past of using real cash and cc. However, as bigger organizations like google and apple push for apple pay and google pay, it brought people a bit closer to online payments. I guess we can assume that if these companies start to use crypto or any sort, the message will be broadcast to a wider audience, and more people will become interested in it. I guess once ICO's using crypto become more widespread, more people will be exposed to it and more people will begin to adapt and join the community. As a app developer, I think crypto can really benefit the app space in terms of payment systems. Some projects that I am currently following that in corporate in-app crypto are: OpenMoney, Kin.
