If we start sharing today and tell them how exactly bitcoin and other cryptos will work as currency, then that can be possible, in my opinion. The only problem that i see is that are they willing to use it despite its complexity and high price.
Using bitcoin as a currency is a choice and there is no way anyone can force any other person to do so. However, I guess the easiest way to make people want to show interest is to create some awareness through merchants accepting the use of bitcoin as a payment method, and in that case, since humans love new things, as long as it is easy for them, they see the value when it comes to that ease and their ability to spend easily without having to be monitored by the government or banks in which they are their own banks, this is something that would easily make it possible to start seeing real life usage.
