Older people may experience some difficulty in understanding the Bitcoin. In my opinion, when paper money was created for the first time, it had taken time.
Just we need acceptance by governments. Then we will have a better economy.
This is one of the reasons of why I think that the adoption of bitcoin and cryptocurrencies in general is going to take a lot of time to actually happen, I really think that there is a generational gap that no matter what we do cannot be filled, older people do not really have any need to use something like bitcoin because they have already invested their whole life and they are already getting good results with their investments, it is the young people that have a reason to use bitcoin but right now they are not very powerful because they do not have a lot of money but give them a few decades and now they are going to be the ones that are at the top and bitcoin will be one of their preferred investments.
