As time goes by, the generation that does not know about Bitcoin will be replaced by a new generation that at least knows more about Bitcoin. You don’t need to worry about the present, because those who will enjoy the benefits of owning and using Bitcoin in the future are those who are currently aware of and understand Bitcoin.
The knowledge and information related to Bitcoin are already available. The decisions of those who do not want to know and have no desire to own Bitcoin are their own business. But of course, they cannot complain about what happens in the future.
