Blockchain is an underlying protocol. When you use Facebook, you’re not thinking about TCP/IP, you’re thinking about sending messages to your friends. Same with other protocols - you're not thinking about HTTP when you're using a website, you will not think about SMTP when you send an email. So, I don’t think in the long run that people will be thinking they’re using bitcoin to send money to a friend. They’ll just be thinking of it as a faster way to get money across without losing money.
