I think it is impossible to do so, just because we have different generations and not all people in the world are able to use smartphones or computers to pay for their goods. Bitcoin will always stay as an online currency and will be used in a few services, where people accept it.
I strongly agree with you, it is very difficult to make Bitcoin a payment tool that can be used by all people, many difficult problems that must be resolved first to make Bitcoin a payment tool, such as education about Bitcoin and equitable infrastructure throughout the world.. so let time run, until the problems that currently confront can be solved by the next generation
